Sang-Gon LEEProf./Ph.DDivision of Computer and Information Engineering, Dongseo University,Director of Innovation Center for Engineering Education(ICEE).
OBJECTIVES Review basic configuration of EIGRP on a serial
interface Configure the bandwidth-percent command Configure EIGRP over Frame Relay hub and spoke Use EIGRP in non-broadcast mode Enable EIGRP manual summarization in topologies
with discontiguous major networks
TOPOLOGY
NOTE:-•Given the diversity of router models and the differing naming conventions for serial interfaces (S0, S0/0, S0/0/0),•The interface numbers on devices will probably differ from those in the topology diagram.
CONTD.. Always draw network diagram to reflect topology. If any uncertainty for DCE connection, then use the show
controllers serial interface_type interface_number command:
HQ# show controllers serial0/0/0
Interface Serial0/0/0
Hardware is GT96K
DCE V.35, clock rate 2000000

SCENARIO
Suppose a company want to a new network between company Headquarter(HQ) , East, and west branches.
They are connected over hub and spoke Frame relay. company headquarter use as Hub.
Each network with multiple loopback interfaces on each router. EIGRP to allow full connectivity between all departments. To simulate the Frame Relay WAN connections. Use a router with three serial ports configured as a frame switch.
STEP 1: ADDRESSING
Apply IP addresses to the loopback interfaces on HQ, East, and West.
Paste the following configurations into routers to begin must be in configuration mode when do this.
HQ:!interface Loopback1ip address 10.1.1.1 255.255.224.0interface Loopback33ip address 10.1.33.1 255.255.224.0interface Loopback65ip address 10.1.65.1 255.255.224.0interface Loopback97ip address 10.1.97.1 255.255.224.0interface Loopback129ip address 10.1.129.1 255.255.224.0interface Loopback161ip address 10.1.161.1 255.255.224.0!end
CONTD..NOTE: all code is same just replace the only 1,
In each address. (HQ=1, East=2, West=3).
As Like: East:- ip address 10.2.1.1 255.255.224.0
West:- ip address 10.3.1.1 255.255.224.0 For now, the IP address is the only configuration on the serial
interfaces. Leave the serial interfaces with their default encapsulation (HDLC)
CONFIGURATIONS Recommendations are described in terms of configuring the
interface "bandwidth" parameter EIGRP being able to use 50 percent of that bandwidth by
default. Bandwidth configuration cannot be changed Bandwidth-percent command should be used to control
the EIGRP bandwidth On low-speed interfaces, raising the available bandwidth for
EIGRP above the default of 50 percent is advisable in order to improve convergence.
CONTD..
LAN Interfaces (Ethernet, Token Ring, FDDI) set by default to the actual media speed bandwidth is explicitly configured to a very low value.
Then need to configure. Point-to-Point Serial Interfaces (HDLC, PPP)
defaults to T1 speed (1.544 Mbps) on serial interfaces set to the actual link speed.
NBMA Interfaces (Frame Relay, X.25, ATM) particularly critical to configure nonbroadcast multi-
access (NBMA) interfaces correctly. otherwise many EIGRP packets may be lost in the
switched network.
CONTD.. Three basic rules
The traffic that EIGRP is allowed to send on a single virtual circuit (VC) cannot exceed the capacity of that VC.
The total EIGRP traffic for all virtual circuits cannot exceed the access line speed of the interface.
The bandwidth allowed for EIGRP on each virtual circuit must be the same in each direction
Three different scenarios for NBMA interfaces Pure Multipoint Configuration (no subinterfaces) Pure Point-to-Point Configuration (each VC on a separate
subinterface) Hybrid Configuration (point-to-point and multipoint
subinterfaces
PURE MULTIPOINT CONFIGURATION (NO SUBINTERFACES) EIGRP will divide the configured bandwidth evenly across
each virtual circuit. Must ensure that this will not overload each virtual circuit. For example:
if you have a T1 access line with four 56K VCs, you should configure the bandwidth to be 224Kbps (4 * 56Kbps) in order to avoid dropping packets. If the total bandwidth of the virtual circuits equals or exceeds the access line speed, configure the bandwidth to equal the access line speed. Note that if the virtual circuits are of different capacities, the bandwidth must be set to take into account the lowest capacity virtual circuit.
For instance, if a T1 access line has three 256Kbps VCs and one 56Kbps VC, the bandwidth should be set to 224Kbps (4 * 56Kbps). In such configurations, putting at least the slow virtual circuit onto a point-to-point subinterface is strongly recommended
PURE POINT-TO-POINT CONFIGURATION (EACH VC ON A SEPARATE SUBINTERFACE)
configuration allows maximum bandwidth control, since the bandwidth can be configured separately on each subinterface
virtual circuits have different capacities. It is best configuration.
total bandwidth for all subinterfaces cannot exceed the available access line bandwidth
If the interface is oversubscribed, the access line bandwidth must be divided across each of the subinterfaces
For Example:- if a T1 access line (1544 Kbps) has ten virtual circuits
with a capacity of 256Kbps, the bandwidth on each subinterface should be configured to be 154Kbps (1544/10) instead of 256Kbps each.
HYBRID CONFIGURATION (POINT-TO-POINT AND MULTIPOINT SUBINTERFACES)
combinations of the two individual strategies Examples :
Dotted Line :- corresponds to separate PVCColor: a separate IP subnet
• To set the interface bandwidth to reflect the PVC capacity, • Adjust the bandwidth prcentage for EIGRP.example, the desired bandwidth for EIGRP is (256K/10)*.9 = 23.04K; the bandwidth percentage would be 23.04K/56K = .41 (41%). So the same effect would be had by configuring: Interface Serial 0.1 point-to-point bandwidth 56 ip bandwidth-percent eigrp 123 41

Each of the ten spoke routers must be configured to limit EIGRP traffic to the same rate as that of the hub, in order to satisfy the third rule

STEP 3: CONFIGURING THE FRAME RELAY ENDPOINTS
Frame Relay(HQ), Spokes (East and West). Check the topology diagram for the data-link connection
identifiers (DLCIs). Off Turn Frame Relay Inverse Address Resolution Protocol
(InARP). Configure all Frame Relay interfaces as physical interfaces. Inverse ARP allows a Frame Relay network to discover the IP
address associated with the virtual circuit A desirable trait in a production network. Turn Inverse ARP off to limit the number of dynamic DLCIs
that are created.
CONTD…
Its work in these pahses;- For a global configuration mode enter the
configuration menu for that assign it an IP address with the help of ip address command.
fourth octet of the IP address is the router number (HQ=1, East=2, West=3
Assign the Frame Relay subnet to be 172.16.124.0 /29.
Enable Frame Relay encapsulation using the interface configuration command encapsulation frame-relay.
Disable Frame Relay Inverse ARP with the no frame-relay inverse-arp command.
CONTD….
Map the other IPs in the subnet to DLCIs, using the frame-relay map ip address dlci broadcast command
HQ# conf tHQ(config)# interface serial 0/0/1HQ(config-if)# ip address 172.16.124.1 255.255.255.248HQ(config-if)# encapsulation frame-relayHQ(config-if)# no frame-relay inverse-arpEast# conf tEast(config)# interface serial 0/0/1East(config-if)# ip address 172.16.124.2

West(config-if)# frame-relay map ip 172.16.124.1 301 broadcast
West(config-if)# frame-relay map ip 172.16.124.2 301 broadcast
West(config-if)# clock rate 64000West(config-if)# no shutdown
CONTD.. Each frame relay end points check the
connectivity across the frame Relay network by the pinging the remote routers.
For more information about this behavior of Frame Relay, see the following FAQ page:
http://www.cisco.com/warp/public/116/fr_faq.pdf
STEP 4: SETTING INTERFACE-LEVEL BANDWIDTH
Set the Frame Relay serial interface bandwidth with the interface-level command bandwidth bandwidth, specifying the bandwidth in kilobits per second. For HQ, use 128 kbps. On East and West, use 64 kbps
by default, EIGRP limits its bandwidth usage to 50 percent of the value specified by the bandwidth parameter.
Each neighbor for which this is an outbound interface has a traffic limit of a fraction of that 50 percent, represented by 1/N, where N is the number of neighbors out that interface
HQ(config)# interface serial 0/0/1HQ(config-if)# bandwidth 128
East(config)# interface serial 0/0/1East(config-if)# bandwidth 64
West(config)# interface serial 0/0/0West(config-if)# bandwidth 64
CONTD…
How much bandwidth on Serial 0/0/1 on HQ is reserved for EIGRP traffic to East?
On HQ, up to 32 Kbps of bandwidth can be utilized for EIGRP traffic to East. This represents one fourth of the total bandwidth of that interface
Control both the bandwidth parameter and the EIGRP bandwidth percentage on a per-interface
On HQ, limit the bandwidth used by EIGRP to 40 percent without changing the bandwidth parameter on the interface.
The interface-level command ip bandwidth-percent eigrp as_number percent:
HQ(config-if)# ip bandwidth-percent eigrp 1 40
STEP 5: CONFIGURING EIGRP Use the global configuration mode command router eigrp
as_number Represented discontiguous network (10.0.0.0/8) configured on
all routers. HQ sends and receives summaries for 10.0.0.0/8 from both
East and West Auto summarization provokes considerable routing disruptions
in the network and turn off auto-summarization on each router. two major networks using here are network 10.0.0.0 for the
loopbacks, and network 172.16.0.0 for the Frame Relay cloud.
Perform this configuration on all three routers
HQ(config)# router eigrp 1
HQ(config-router)# network 10.0.0.0
CONTD..HQ(config-router)# network 172.16.0.0
HQ(config-router)# no auto-summary Same for East and West
Issue the show ip eigrp topology command on East:
East# show ip eigrp topology

Which networks are missing from the topology database?
All of the subnets in the 10.3.0.0/16 range are missing from East’s topology table. These are the remote loopback interfaces on the West router.
What do you suspect as being responsible for this problem?
This problem is caused by the split horizon functionality on R1. R1 will not send route updates from East to West because the incoming interface and outgoing interface are the same.
CONTD..
Router 1 needs the no ip split-horizon eigrp as_number command on its serial Frame Relay interface
This command disables split horizon for an EIGRP autonomous system
If split horizon is enabled (the default), route advertisements from East to HQ do not travel to West and vice versa,
Example :
HQ(config)# interface serial 0/0/1
HQ(config-if)# no ip split-horizon eigrp 1

If anybody never used TCL scripts or need a refresher, see the TCL lab in the routing module.
STEP 6: USING NON-BROADCAST EIGRP MODE EIGRP use as default mode, which multicasts packets to the link-
local address 224.0.0.10 All Frame relay not support mulitcast. EIGRP supports unicasts to remote destinations using non
broadcast mode on a per-interface basis mode is analogous to configuring RIPv2 with a passive interface
and statically configuring neighbors out that interface To implement this functionality, do the following:
HQ(config)# router eigrp 1
HQ(config-router)# neighbor 172.16.124.2 serial 0/0/1
HQ(config-router)# neighbor 172.16.124.3 serial 0/0/1
East(config)# router eigrp 1
East(config-router)# neighbor 172.16.124.1 serial 0/0/1
West(config)# router eigrp 1
West(config-router)# neighbor 172.16.124.1 serial 0/0/0
CONTD…
HQ now has two neighbor statements, and the other two routers have one. Once you configure neighbor statements for a given interface, EIGRP automatically stops multicasting packets out that interface and starts unicasting packets instead. verify that all your changes have worked with the
show ip eigrp neighbors command:

STEP 7: IMPLEMENTING EIGRP MANUAL SUMMARIZATION
Implement EIGRP manual summarization on each of the routers. Each router should advertise only one network summarization.
What is the length of the network mask that is used to summarize all the loopbacks on each router?
Summarize all the loopbacks at the 24-bit boundary for each router. Simplified EIGRP topology table on each router using the show ip
eigrp topology command:
