Virtualized SNMP Management restrict access at a VRF-Lite level using either SNMPv1/2 orSNMPv3 applies to release 5.x

Starting in release 7.0, Enterprise Device Manager (EDM) can be used to configure VRF-Lite

VRF-Lite Multicast Support (software release 5.1) :

PIM-SM, PIM-SSM, IGMPv1,v2,v3 protocols are virtualized and can be configure in non-zeroVRF

PIM-SM / PIM-SSM support upto 64 instances Max number of OSPF and RIP v1/v2 instances have also been increased to 64 in this release. Virtualized multicast features support on MLT/SMLT/RSMLT related topologies Partial HA support for virtualized multicast functionalities The following multicast features are not virtualized:

o PIM-DMo IGAPo DVMRPo PGM

o PIM-MBR Virtualization is supported only on R/RS modules and on 8692 CPU card Multicast Virtualization is available only in Premier license

Multicast VLAN registration (software release 7.0)

Multicast VLAN Registration (MVR) allows the single multicast VLAN to be shared in the networkwhile subscribers remain in separate VLANs

MVR is based upon IGMP Snoop, but these 2 features can work independently of each other When a multicast data stream is received to MVR vlan, it will be replicated to all receiver vlan

associated/bind to MVR vlan MVR functionality is virtualized, it means each vrf can have its own MVR vlan Only one vlan can be configured as MVR vlan in a vrf When a Report/Leave is received, it will be forwarded to mrouter port

IP- VPNs can be connected together in several ways across a core network using any of the followingmethods:

VRF

o Multiple VRF instances are used between ERS 8600/8800 switches as shown in figure 2,3, and 4 below showing VRF support between switches, VRRP, RSMLT, and SMLTsupport

o For each VRF, a separate VLAN must be created between ERS 8600/8800 switcheso VLAN tagging can be used between

MPLS

o MPLS network is used as a transport for IP- VPNs usi ng RFC 4364 as shown in figure 5below

IP VPN-Lite

o IP VPN-Lite can be used to build IP- VPNs across any routed IP core using MP -iBGP forVPN exchange as shown in figure 6 below

o Please refer to Technical Brief titled Technical Brief for IP VPN-Lite for Ethernet RoutingSwitch 8600 for more details

SPBM

o SPB L3 VSNs can be used to build IP- VPNs across an SPBM core using IPVSNReachability TLV 184 to distribution IPVSN reachability between IS-IS peers as shown infigure 7 below

o A Backbone Service Instance Identifier (I-SID) is assigned at a Virtual Router (VRF) level

All VRFs that share the same I-SID can participate in the same VSN

o Please refer to Technical Configuration Guide titled Shortest Path Bridging (802.1aq) forERS 8600 / 8800 Technical Configuration Guide for more details

Multicast

o Multicast virtualization for VRF-Lite is supported and shown in figure 8 below in additionto support for MVR as illustrated in figure 9

2. Base Scenario:This technical brief covers configuration examples only pertaining to VRF-light for the ERS 8600/8800.

2.1 Assumptions:It is assumed that general knowledge of routing and SMLT on Avaya switches is understood.

2.2 VRF-Lite ConfigurationIn the 5.0 software release or latter, the concept of global routing table and virtual routing table(s) isintroduced. The global route table (GRT) is also referred to as VRF0 and refers to the main global routingtable. For each virtual routing instance, it will be referred to by the instance number you assign to theVRF; for example VRF1 refers to virtual router instance 1. Overall, there is only one global routing table(VRF0) and up to 255 virtual routing tables (VRF1 up to VRF255). The VRF instance can be createdusing either CLI, SNMP (5.x), or EDM ( 7.0).

For each VRF-Lite instance that you create, you will need to specify the routing protocol or protocols thatyou wish to enable for this VRF instance. This can include OSPF, RIP, and/or BGP. As an option, youcan also limit the number of routes allowed per VRF instance.

The order of VRF-Lite configuration is as follows:

1. Create VRF instance(s)2. Enable IGP routing protocol you wish to enable per VRF, i.e. enable OSPF, RIP, and/or BGP per

VRF instance3. As an option, configure the number of routes allowed for each VRF4. Create the VRF VLAN(s) and add port members5. If using JDM

a. At this stage, only if using Java Device Manager (JDM) for software release 5.x, you mustselect the VRF instance to further configure the VRF if you are a JDM Super User.

b. If you are a JDM VRF user, you must logon to the switch with the appropriate credentials(community string if SNMPv1/2 or USM user if SNMPv3).

c. Please see section titled JDM : VRF-Lite SNMP Access for ERS 8600 software release5.x below for more details.

6. If using EDM,a. If using software release 7.0, you can select the VRF context at the EDM login screenb. If using software level 7.1 or higher, after loggin in via the global user credentials, you

can select the VRF context available via the left navigation plane VRF Context view c. Please see section titled EDM: VRF-Lite http Access for ERS 8800 software release 7.x

for more details7. Add IP address and routing protocol(s) at a VLAN level for each VRF instance.8. Add optional route policies if required. You can also use route policies if you wish to leak routes

between VRF instances or to the global route table.

2.3 Basic VRF-Lite Configuration StepsThe following are the steps used to configure a VRF instance, adding an IP address, and enable a routingprotocol using CLI, JDM (5.x), and EDM ( 7.0) .

2.3.1 Initial VRF Configuration

2.3.1.1 Logon to the ERS 8600/8800 switch using ether CLI, Java Device Manger (5.x), or EDM(7.0 or higher)

You can use either CLI, JDM, or EDM to configure the ERS 8600/8800 for VRF-Light.

2.3.1.2 Create VRF instances

By default, the maximum routes per VRF instance is set to 10,000 routes

By default, SNMP trap is enabled is the maximum route is reached

CLI Step 1 Create VRF instance, add maximum routes (optional), and routing protocol

CLI

ERS8000-1:5# config ip vrf create id

ERS8000-1:5# config ip vrf max-routes

ERS8000-1:5# config ip vrf create

ERS8000-1:5# config ip vrf enable

ACLI

ERS8000-1:5(config)# ip vrf vrfid

ERS8000-1:5(config)# ip vrf max-routes

ERS8000-1:5(config)# router vrf ERS8000-1:5(router-vrf)# ip

ERS8000-1:5(router-vrf)# exit


18/53


avaya.com

JDM (release 5.x) Step 1 Create VRF instance. To to IP -> VR F -> Insert and select the routingprotocol(s) and maximum routes (optional)

EDM (release 7.0) Step 1 Create VRF instance. To to IP -> VR F -> Insert and select the routingprotocol(s) and maximum routes (optional)


19/53


avaya.com

2.3.1.3 Create VLANs

Create VLAN(s) and add port members

Once you have create the VLAN(s), you can add the VRF instance to the corresponding VLAN

CLI Step 1 Assign VRF instance to VLAN

CLI

ERS8000-1:5# config vlan vrf

ACLI

ERS8000-1:5(config)# interface vlan

ERS8000-1:5(config-if)# vrf

ERS8000-1:5(config-if)# exit

JDM (release 5.x) Step 1 Assign VRF instance to VLAN. After you have created the VLAN(s), viaVLAN -> VLANs Glob lRouter (vrf 0) - > Bas ic (click on corresponding VLAN id, click on Vrfid andselect the VRF ID you wish to use for this VLAN


20/53


avaya.com

EDM (release 7.0) Step 1 Create VRF instance. After you have created the VLAN(s), viaConf igura t ion ->VLAN -> VLANs - > Bas ic (go to the corresponding VLAN id, click on Vrfid andenter the VRF ID you wish to use for this VLAN

2.3.2 VRF Context User access to VRF context using SNMP / WEB Browser

Depending of the software release used, you can change the way a user can access VRF context.

In software release 5.x, SNMP is used to access a specific VRF instance or instances.

In software release 7.0, when logging into EDM, in addition to entering a user name andpassword, you will also have to enter a VRF Name. By default, a VRF name of GlobalRouter isused to access the Global Router view.

In software release 7.1, when logging into EDM the user is only offered the Global Router view. Auser can select a specific VRF where a new browser tab will be opened for the selected VRFview. A user can choose to view and manipulate the different VRF view simultaneously.

2.3.2.1 JDM : VRF-Lite SNMP Access for ERS 8600 software release 5.x

As mentioned above, SNMP (release 5.x) can be used to allow 3 rd party or partner access to a specificVRF instance or instances. Please note that only SNMP can be used to visualize management access ata VRF level; CLI access at a VRF level is not supported at this time.

If you wish to enable SNMP at a VRF level, both SMNPv1/2 and SNMPv3 can be used. SNMPv3 accesscontrol at a VRF level is accomplished using the USM model. If SNMPv1/2 is used, access is controlledvia community strings.

Overall, there are two types of users supported with VRF-light, Super Users and VRF users.

Super User Has full access to switch using ether JDM or CLI Has access to global route (GRT) and each VRF instance

o The Super User must either select Global Router instance or a specific VRF instance Configures all VLANs (global and VRF) and assigns initial IP address for each VRF via the

Global Router instance The Super User must ether select the Global Router instance or a VRF instance

o Cannot select both at the same time


21/53


avaya.com

o If a VRF instance is selected, only the VFP specific fields and parameters will beconfigurable and displayed

o The Super User must select Global Router instance initially to configure the VRF

instances, VRF VLAN(s), and routing protocols allowed for each VRF instance At this stage, either the Super User or a VRF User can be used to continue theVRF configuration

If the Super User wishes to continue the VRF configuration, he/she must firstselect the VRF instance.

VRF User

Has access only at a VRF level SMNP access only VRF access level is configured by the Super User SNMPv3 support via USM model SNMPv1/2 support via community string

o Default: public::x and private::x where x = 1 to 255 (VRF instance)

Only the Super User can add VLANs, VRF instances The VRF user can add IP addresses, routing protocols, and other IP parameters pertaining onlyto the VLANs configured by the Super User.

The VRF user can only view routes, arp, MAC addresses, etc for the VLANs configured by theSuper User

2.3.2.1.1 SNMP Global Router and VRF Selection Super User

Assuming you have already configured the VRF instance(s) and VRF VLAN(s), to select the VRFinstance using Java Device Manager (JDM), go to IP -> VRF, select the VRF instance, and then click onSet Current VRF as shown below. From now on, only the fields pertaining to this VRF will be displayed.

2.3.4 VRF Configuration Adding IP Related Parameters

2.3.4.1 If using SNMP only via JDM (release 5.x), either select VRF instance via Super User orlog-in via a valid VRF user for the corresponding VRF instance

At this point, you can need to select the VRF instance where you wish to configure the IP relatedparameters. If you are using a VRF user interface to configure the VRF instance, you must open up aJDM connection using the correct user credentials that belong to the VRF instance. Either SNMPv1/2 orSNMPv3 can be used. If using SNMPv3, the Super User must first create the VRF SNMPv3 users.

Using JDM Step 1 Super User, go to IP -> VRF and select the VRF instance

3. VRF-Lite Configuration Example

Figure 10: VF-Lite Configuration Example

For this configuration example, two IP-VRF instances will be added, VRF1 using a name of vrfone andVRF2 using a name of vrftwo . RSMLT will be enabled on both VRF instances along with the SLT ID, IPaddress and IGP protocols as shown in figure 5 above. For this example, we will only add theconfiguration for VLAN 601 to Switch-1 and VLAN 700 to Switch-2. Realistically, more than one routerwould normally be connected to each VRF instance in addition to the core configuration. However, thepurpose of this example is to simply demonstrate how to configure VRF instances locally at an edge levelusing SMLT. In the core, either VRF, IP VPN-Lite, or MPLS can be deployed.

In addition, assuming ERS8000-1 and ERS8000-2 are using software level 5.x, we will configure threeSNMPv3 USM users with the following user names:

vrf0user: Super User

vrfone: VRF1 user to manage VRF1 only

vrftwo: VRF2 user to manage VRF2 only

4. Routing between VRFs

4.1 Configuration Leaking Routes between VRF InstancesThere may be times where you may wish to inject routes between VRFs for various reasons. Forexample, you may have a case where there is service on a particulate VRF, i.e. VRF10, which you alsowould also like to use on other VRFs. Instead of duplicating the service on each VRF, you could injectthe service routes from VRF 10 to the other VRFs that require the use of this servi ce. In the otherdirection, you will also need to inject the routes from the other VRFs that require the service back toVRF10.

In this example, using the base configuration from the configuration example in section 3, we will enablethe leaking of routes between VRF1 and VRF2. Overall, we will accomplish the following:

Enable re-distribution of direct interfaces between VRF1 and VRF2

Only re-distribute network 172.1.25.0/24 from VRF2 to VRF1 Only re-distribute network 192.33.34.0/24 from VRF1 to VRF2

4.1.1 ERS 8600/8800 Configuration

4.1.1.1 Enable ASBR

In order to re-distribute static routes, you must enable OSPF ASBR on vrf 1.

ERS8000-1 Step 1 Enable OSPF ASBR for vrf 1


ERS8000-1:5(router-vrf)# ip ospf as-boundary-router enable


ERS8000-2 Step 1 Enable OSPF ASBR for vrf 1

ERS8000-2:5# config ip vrf vrfone ospf as-boundary-router enable

4.1.1.2 Add static routes

ERS8000-1 Step 1 Create Static route for vrf 1


ERS8000-1:5(router-vrf)# ip route 172.1.25.0 255.255.255.0 172.1.1.5 weight 1 next-hop-vrf vrftwo



ERS8000-2:5# config ip vrf vrfone static-route create 172.1.25.0/24 next-hop 172.1.1.5cost 1 next-hop-vrf vrftwo

ERS8000-2:5# config ip vrf vrftwo static-route create 192.33.34.0/24 next-hop10.1.11.3 cost 1 next-hop-vrf vrfone

4.1.1.3 Enable Route Re-distribution

We will also have to re-distribute the direct interfaces in order for either Switch-1 or Switch-2 to get to theremote networks.

ERS8000-1 Step 1 For vrf 1, enable OSPF re-distribution of static routes from VRF source of vrf2


ERS8000-1:5(router-vrf)# ip ospf redistribute static vrf-src vrftwo

ERS8000-1:5(router-vrf)# ip ospf redistribute static enable vrf-src vrftwo

ERS8000-1:5(router-vrf)# ip ospf redistribute direct vrf-src vrftwo

ERS8000-1:5(router-vrf)# ip ospf redistribute direct enable vrf-src vrftwo


ERS8000-2 Step 1 For vrf 1, enable OSPF re-distribution of static routes from VRF source of vrf2

ERS8000-2:5# config ip vrf vrfone ospf redistribute static create vrf-src vrftwo

ERS8000-2:5# config ip vrf vrfone ospf redistribute static enable vrf-src vrftwo

ERS8000-2:5# config ip vrf vrfone ospf redistribute static apply vrf-src vrftwo

ERS8000-2:5# config ip vrf vrfone ospf redistribute direct create vrf-src vrftwo

ERS8000-2:5# config ip vrf vrfone ospf redistribute direct enable vrf-src vrftwo

ERS8000-2:5# config ip vrf vrfone ospf redistribute direct apply vrf-src vrftwo


49/53

ERS8000-1 Step 2 For vrf 2, enable RIP re-distribution of static routes from VRF source of vrf 1


ERS8000-1:5(router-vrf)# ip rip redistribute static vrf-src vrfone

ERS8000-1:5(router-vrf)# ip rip redistribute static enable vrf-src vrfone

ERS8000-1:5(router-vrf)# ip rip redistribute direct vrf-src vrfone

ERS8000-1:5(router-vrf)# ip rip redistribute direct enable vrf-src vrfone


ERS8000-2 Step 2 For vrf 2, enable RIP re-distribution of static routes from VRF source of vrf 1

ERS8000-2:5# config ip vrf vrftwo rip redistribute static create vrf-src vrfone

ERS8000-2:5# config ip vrf vrftwo rip redistribute static enable vrf-src vrfone

ERS8000-2:5# config ip vrf vrftwo rip redistribute static apply vrf-src vrfone

ERS8000-2:5# config ip vrf vrftwo rip redistribute direct create vrf-src vrfone

ERS8000-2:5# config ip vrf vrftwo rip redistribute direct enable vrf-src vrfone

ERS8000-2:5# config ip vrf vrftwo rip redistribute direct apply vrf-src vrfone
