3 INTRODUCTION This document provides an overview of the testing and results that Isocore Internetworking Lab conducted to evaluate the scalability and reliability of the Cisco Systems 7600 series edge routers. The six slot platforms (7606) were primarily used for most of the tests. Isocore Internetworking Lab conducted a comprehensive independent evaluation of the Cisco Systems 7600 series routers to assess the scalability in the areas of Layer 2 and Layer 3 services, routing, QoS, and to further validate the stability and reliability with heavily loaded configurations. 7600’s deterministic scaled performance definitely establishes it as highly scalable and reliable platform in its class of IP/MPLS edge routers and metro Ethernet space.

3.1 CISCO SYSTEMS 7600 SERIES EDGE ROUTER OVERVIEW Cisco 7600 series edge routing platform is available in 4 different form factors: a 4 slot 7604, 6 slots 7606, 9 slots 7609 and 13 slots 7613. Isocore tests evaluated 7606, 7609 and 7613. Cisco Systems 7600 supports one primary and one possible redundant central supervisor consisting of control processors, forwarding ASICs and integrated switch-fabric. Cisco 7600 router supports families of high density Ethernet line cards, modular Shared Port Adapter (SPA) Interface Processor (SIP) and Service enabled line cards. The SIPs are capable of accepting variety of Low- and High-Speed Interfaces ranging from DS0 to 10GE/OC192. The test chassis 7606 had a combination of SIP-400 with 1G interfaces, SIP-600 with either 1G or 10G interfaces, along with LAN only capable ports. All platforms use the same Cisco Systems IOS and same SPAs can be used across different platforms. The applicability of such a platform is in the areas of Carrier Ethernet, Quad-play services, mobile and wireless backhauling applications.

3.2 TEST METHODOLOGY AND SYSTEM TEST BED The primary focus of the test effort was to demonstrate the performance, scalability and stability of multiple simultaneous services on Cisco Systems 7600 series edge routing platform, and to verify the capabilities that are needed for successful deployment as an edge routing platform in the IP/MPLS next generation networks. The tests that were conducted focused on evaluating the key capabilities of 7600 edge routing platform in the areas:

1. Scaling of multiple simultaneous services 2. QoS performance and scaling 3. Layer 2 service scaling including Point-to-Point Pseudowires, VPLS, H-VPLS with MPLS or

QinQ Edge and Ethernet L2 Services using Multi-Point Bridging 4. Routing Protocol Scaling 5. MPLS TE Fast Re-Route convergence

The first test was set up to evaluate the ability of the 7600 to scale to maximum number of services that could be configured on the platform. The services supported should be a combination of Layer 2 P2P Ethernet services (EoMPLS), Virtual Private LAN services (VPLS), Ethernet Multi-Point bridging, and Layer 3 VPNs with large number of BGP routes in the VRF along with large number of IGP routes in the public domain simulating plain Internet traffic. This test in particular was one of the most complicated of all the tests conducted as part of this test effort. In addition to the control plane



scalability, forwarding plane verification was also done using streams configured to target each MAC address and each advertised route in layer 2 and layer 3 services, respectively. The QoS test setup employed as part of this effort was complex and many iterations were performed to validate the capabilities of various SPA Interface processors supported on the Cisco Systems 7600 platform. These tests validated the scalability of number of queues that could be configured, the ability of 7600 to ensure SLA guarantees using shaping and policing configurations. The 7600 platform was evaluated for its shaping and policing accuracy when multiple traffic classes at different rates were configured. These tests were performed with different traffic types including IMIX and fixed size packets. Protocol scalability testing covered BGP and IGP (IS-IS and OSPF) routing protocols. The primary focus was to demonstrate the maximum number of routes supported in the FIB, and maximum number of BGP peering that can be maintained consistently at the max number of routes in the FIB. Furthermore, for IGP the focus was only to verify the maximum number of routes capacity of the 7600 platform. The test also focused on evaluating the EoMPLS scalability when PWs are mapped to MPLS TE/FRR tunnels. Here the primary objective was to measure the failover performance times, and demonstrate that the observed number of packets lost due to a local failure does not exceed the 50 msec worth of traffic loss and consequently services that are carried over FRR tunnels are not affected. Furthermore, OAM functionality was verified during the service scalability test. The Cisco Systems 7600 multiple simultaneous service testing, layer 2 scaling testing, routing scaling were conducted at Isocore Internetworking Lab facilities in Northern Virginia with on-site support from Cisco Systems engineers and remote support from IXIA. The QoS performance tests, TE/FRR tests, and H-VPLS tests, and IS-IS/OSPF scaling tests were performed at Cisco Systems offices in Raleigh, NC, USA. TE/FRR and H-VPLS tests were performed using Agilent technologies N2X platform.

4 TEST OVERVIEW

4.1 MULTIPLE SIMULTANEOUS SERVICE SCALABILITY One of the main focuses of the evaluation effort was to validate the scalability of the 7600 series edge router, when more than one service is configured on the platform. This test validated the unprecedented stability of the platform under the extreme loading conditions of maximum number of service instances in addition to the IGP routes. The test confirms the service scaling of the 7600 platform, and further validates its ability to scale to large number of interfaces and concurrently support multiple services over same common interfaces. In this test, 7600 successfully and stably scaled to 15,000 Layer 2 and Layer 3 services concurrently, with traffic being sent to all advertised networks within the layer 3 context and MAC addresses within the layer 2 contexts. The reference graphs demonstrating the traffic rates to all advertised destinations are provided in figure 4.A.



Multiple Simultaneous Service Scalability Verification – Test Findings

15,000 service successfully configured and verified near line rate traffic • 8,000 EoMPLS services with 4,000 VLANs configured per port • 4,000 L2 Ethernet Services using Multi-Point Bridging circuits with Layer 2 trunks in the core • 2,000 VPLS instances • 1,000 L3VPN Instances with traffic sent from 240,000 routes in VRF to 240,000 routes in the

remote VRF fully meshed. • 1,000 EBGP Instances + 500,000 BGP FIB entries • 10,000 OSPF routes • All services configured over LDP

4.2 QOS SCALING AND PERFORMANCE The primary objective of these series of tests was to evaluate the performance and scalability of QoS implementation on Cisco System 7600 series edge routing platform. The test results demonstrate the ability of the device to scale to a very large number of 32,000 Queues. The tests



were performed on both SIP-400 and SIP-600 line cards with different queuing scaling numbers as mentioned in the table below. These tests1 demonstrated that consistent average latency times for priority traffic were in the range of 85 to 105 µsecs across multiple tests. The tests also successfully demonstrated the application of hierarchical policy map with shaping on class-default in the parent policy and a policed priority class along with seven class-based weighted fair queues in the child policy map. The policy map is applied to each sub-interface in the majority of tests. The injected traffic for verifying the application of policies was verified with a combination of fixed size on priority classes and IMIX on other classes or fixed-size packets on all the classes. Highlights of the QoS performance and scalability test are provided in the table below along with some graphs demonstrating the consistent observations for policing and shaping accuracies.

4.3 L2VPN SCALABILITY (EOMPLS, VPLS, H-VPLS AND BRIDGING) This test was conducted to evaluate the capability of the Cisco Systems 7600 series edge routers in terms of scaling of P2P and multi-point VPLS services. The tests1 validated 7600 series routers ability to scale P2P Ethernet Pseudowires per platform basis and per interface basis. Furthermore, for the VPLS service scalability, the tests validated 7600s ability to scale to very high number of services in VPLS mode, and hierarchical VPLS mode. The tests implemented 16,000 concurrent Ethernet Pseudowires, with traffic sent on each VLAN circuit attached to these services. More impressive, 7600 was able to demonstrate VPLS scalability of up to 4,000 Virtual Forwarding Instances (VFIs) along with 32,000 PW sessions. Each VFI was configured with 8 peers. However these scalability numbers were evaluated separately at different instance of time. In addition, Ethernet multi-point bridge scalability was also validated. The table below summarizes the results of the layer 2 VPN scalability tests.

1G circuits • L2 Ethernet Service Scalability using Multi-Point Bridging

o 12,000 Total E-MPB attachment circuits per platform Isocore validates the ability of the 7600 series edge routers to scale to significant numbers of PW sessions within VPLS context. Furthermore, this test validates unsurpassed scalability of the Pseudowire control plane on the 7600 series edge routers. It is to be noted that unique component of the tests was that these scalability numbers were achieved through minimal number of iterations to obtain this level of results, this further demonstrate the reliability of 7600 series platform in producing reliable results repeatedly.

4.4 MPLS TE/FRR FAILOVER CONVERGENCE WITH EOMPLS The primary focus of this test was to validate the ability of the 7600 series edge routers to be able to map large number of PW sessions across uni-directional TE label switched Paths1. The FRR was configured to validate both link protection and node protection scenarios under scaled load of 12,000 PWs between the PE devices mapped on to 350 TE tunnels and 150 background tunnels were configured to verify the impact of background tunnels on the failover performance times. The EoMPLS circuits were mapped to the 350 tunnels configured on the PE as the head-end using the tunnel select feature offered in the Cisco Systems IOS; this ensures that the EoMPLS circuits are evenly mapped to these tunnels. In terms of measurements, the test focused on measuring the failover performance times when a link or a node failure is induced. In all the Scenarios the 7600 series edge routers demonstrated failover recovery times in the range of less than 5 msecs. Table below summarizes the test results of this test.

MPLS TE/FRR Convergence with Scalable EoMPLS PWs – Test Findings • 12,000 Scalable EoMPLS PWs and 500 TE/FRR Tunnels

o 7600 Configured to use tunnel select feature o 350 Primary TE/FRR Tunnels under test. o 150 background tunnels to verify the stability of the other PWs not affected by any

failures. o No traffic impact was observed on the background tunnels o Consistent very low failover performance times in the order of 0.73 to 0.84 msec

in case of link protection o Consistent very low failover performance times in the order of 4.39 to 4.62 msecs

for the case of node protection. o Traffic rates varied from 65% to 95 % line rate of 1G traffic offered to the test bed o Frame size set to 1,000 byte packets

These tests were conducted using the scalable EoMPLS PWs. The results might be different for hardware based EoMPLS or VPLS PWs.

4.5 ROUTING PROTOCOL AND FORWARDING SCALABILITY CAPACITY TEST

Isocore validated the Cisco Systems 7600 series routers ability to scale to large number of route entries in its Routing information base, and in forwarding information bases. Additionally, the interface scalability test was also conducted for BGP protocol, where 7600 edge routing platform demonstrated unmatched route and peering scalability. Furthermore, 7600 edge routing platform proved its robust stability and scalability during the IGP route scalability test. All the above tests were validated for data plane reliability by sending traffic to each routing destination advertised during the scalability test. Cisco Systems 7600 edge routing platform demonstrated the stability of its BGP implementation by simultaneously scaling the peering sessions, as well as route entries in the forwarding information base. This test was run for 12 hours, and 7600 maintained 3,963 E-BGP sessions, and 1 million route entries in its FIB, and traffic was continuously forwarded to all 1 million advertised routes with 64 byte traffic streams. The routing protocol test also validated the ability of 7600 control plane to store large number of IGP routes. 7600 platform successfully demonstrated the ability to support 300,000 IS-IS and OSPF routes.

Routing Protocol Scalability – Test Findings • DUT successfully supported 1 million unique routes (FIB entries) • 3.85 million unique BGP Paths • 3,963 E-BGP Peers with 1,000,750 FIB entries

o 3,963 E-BGP peers with 250 routes unique routes per E-BGP Peer o 10,000 Unique routes from I-BGP peer o Total number of FIB Entries 1,000,750 routes o 16 Ports used with 250 E-BGP peers configured per port o Frame size used to verify the data plane – 64 bytes with aggregate traffic rate of o 64 byte packets streams at 90% of line rate traffic o No traffic drops observed

• Successfully implemented 300,000 IS-IS routes with 75 Peers • Successfully implemented 300,000 OSPF routes with 32 Peers

Isocore validates the ability of 7600 edge routing platform demonstrating flawless stability under extreme stress conditions due to large number of RIB and FIB entries. The BGP max peering and max route tests were run with traffic for 12 hours.

5 CONCLUSIONS Isocore’s comprehensive testing of Cisco Systems 7600 edge routing platform demonstrates the capability to support multiple simultaneous services in an extensive scalable and heavy-load environment. During the entire test series, 7600 platform did not show any signs of hardware or software limitations or instability. Numerous service providers have indicated that scalability, flexibility, reliability and QoS support with multiple simultaneous services are critical factors to be



considered as requirements for any edge platform for the next generation network deployments. Cisco Systems 7600 edge service platform definitely fulfills all of these key requirements. During the multiple simultaneous service scaling tests, Cisco Systems 7600 platform demonstrated utmost stability and flexibility when the test bed was subjected to extreme load conditions due to update and withdrawal of large number of BGP routes within the VRFs, flapping of access circuits in the EoMPLS configuration to ensure that the tester VLAN configuration matches with the DUT and this was repeated number of times during the test setup process. Remarkably 7600 platform did not demonstrate any signs of instability or loosing functionality in layer 2 service, when layer 3 services is subjected to additional stress. This part of the test further validated control plane stability of 7600 platform under extreme load conditions. Furthermore, when evaluating maximum peering capacity in the BGP scalability testing, 7600 comfortably demonstrated route scalability with maximum number of BGP peers configured. This also validates 7600’s abilities as an edge platform capable of supporting large number of Layer 2 services along with maximum layer 3 routes scalability. The extensive testing conducted by Isocore Internetworking Lab validates 7600’s capabilities in the areas of stability, flexibility, reliability and Quality of Service, and multiple simultaneous scaling. During the testing effort, large configurations were built due to the large scale of the tests, further validating the stability of 7600 edge routing platform. The results observed during this effort compliment the hardware flexibility of 7600 platform with integrated Ethernet switching and carrier class IP/MPLS routing. Furthermore, flexibility offered by shared port adaptors (SPA) and SPA interface processors (SIP) helps in achieving desired prioritization of various classes of services as demonstrated by the QoS results and ensure strict SLAs for the service providers. In conclusion, based on the results observed and verified in testing of the 7600 platform, Isocore confirms the IP/MPLS routing and scaling of multiple simultaneous services and believes that the Cisco Systems 7600 series meets the next generation requirements of Provider’s edge router.
