Routing – eigrp configuration problem over frame-relay

eigrpframe-relayrouterrouting

I have a set up with back to back connection with EIGRP over frame-relay, mention below the device connection setup using GNS3.

Problem is: I am configuring EIGRP over frame-relay, but its not showing EIGRP neighbors under show ip route command output. Please help me on it..

These are the configuration on routers between R1 and R2; I removed keepalives and am using the same DLCI in frame-relay.

R1:

conf t
int se0/0
ip add 131.1.12.1 255.255.255.0
encapsulation frame-relay
no keepavlive
frame-relay map ip 131.1.12.2 100
no sh

router eigrp 100
network 131.1.12.0 0.0.0.255

R2:

conf t
int se0/0
ip add 131.1.12.2 255.255.255.0
encapsulation frame-relay
no keepavlive
frame-relay map ip 131.1.12.1 100

int fa1/0
ip add 131.1.23.2 255.255.255.0
no sh

router eigrp 100
net 131.1.12.0 0.0.0.255
net 131.1.23.0 0.0.0.255

Update after one.time's answer:

Thanks for your reply.

I have two issues.

1) I had done the configuration as per your guidelines, now its working fine. But the problem is i cant able to ping the any of the routers own interfaces from the router itself and from the same rotuer i can able to ping other neighbors. mentioned the one router config and ping results below.

R2:-

interface Loopback0
 ip address 2.2.2.2 255.0.0.0
!
interface Serial0/0
 ip address 131.1.12.2 255.255.255.0
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay map ip 131.1.12.1 100 broadcast
!
interface FastEthernet1/0
 ip address 131.1.23.2 255.255.255.0
 duplex auto speed auto
!
router eigrp 100
 network 2.0.0.0 0.0.0.0
 network 2.0.0.0
 network 131.1.12.0 0.0.0.255
 network 131.1.23.0 0.0.0.255
 no auto-summary

Ping results :-

Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 131.1.23.1, timeout is 2 seconds:

2) i want to setup my devices like:- -R2 and R3's interface should be confiugred to be in vlan 23. -R1 and R2,R3 and R4 should be configured in a frame-relay multipoint manner but do not use a sub-interface to accomplish this task.

Best Answer

There are a few ways to accomplish a back-to-back frame-relay connection.

A quick search returns the following options:

Your configuration is closer to hybrid switching, however, you're missing a few key elements.

Frame-Relay

Either R1 or R2 will need to have frame-relay switching enabled to act as the frame-relay switch. 

R1(config)#frame-relay switching

The newly designated frame switch's Serial0/0 interface needs to be changed to the frame-relay interface type dce in order to provide LMI.

R1(config)#int s0/0
R1(config-if)#frame-relay intf-type dce

Finally you don't need to include the no keepavlive syntax when performing hybrid switching.

EIGRP

Your matching(required) static frame-relay map statements may include the broadcast statement in order for EIGRP to establish a neighbor adjacency. 

R1(config)#int s0/0
R1(config-if)# frame-relay map ip 131.1.12.2 100 broadcast

R2(config)#int s0/0
R2(config-if)# frame-relay map ip 131.1.12.1 100 broadcast

IP: s=131.1.12.1 (local), d=224.0.0.10 (Serial0/0), len 60, sending broad/multicast
Serial0/0(o): dlci 100(0x1841), pkt type 0x800(IP), datagramsize 64
Serial0/0(o):Pkt sent on dlci 100(0x1841), pkt type 0x800(IP), datagramsize 64

Without the broadcast statement, EIGRP messages sent to the multicast address 224.0.0.10 will fail to be encapsulated.

IP: s=131.1.12.1 (local), d=224.0.0.10 (Serial0/0), len 60, sending broad/multicast
Serial0/0: broadcast search
Serial0/0:encaps failed on broadcast for link 7(IP)
IP: s=131.1.12.1 (local), d=224.0.0.10 (Serial0/0), len 60, encapsulation failed

Unicast EIGRP

Or, instead of using the broadcast keyword with your static frame-relay map statements to avoid encapsulation failures, you can specify EIGRP unicast neighbors under EIGRP process 100 and your adjacency should form.

R1(config-if)#router eigrp 100
R1(config-router)#neighbor 131.1.12.2 s0/0
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 131.1.12.2 (Serial0/0) is down: Static peer configured
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 131.1.12.2 (Serial0/0) is up: new adjacency

R2(config-if)#router eigrp 100
R2(config-router)#neighbor 131.1.12.1 s0/0
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 131.1.12.1 (Serial0/0) is down: Static peer configured
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 131.1.12.1 (Serial0/0) is up: new adjacency
