FRAME RELAY ROUTER NOT LET ME ADVERTISE EIGRP ROUTES

                   I have a basic topology

MY QUESTION IS :

===================

I AM ABLE TO PING IP ADDRESS 172.16.0.1, 172.16.0.2,172.16.0.3 . But when i configure eigrp...it is configured properly...

My frame relay mapping is also done properly and it is active as well...

I am not able to see eigrp routes.

     172.16.0.0/29 is subnetted, 1 subnets

C       172.16.124.0 is directly connected, Serial0/0.1

     10.0.0.0/24 is subnetted, 3 subnets

C       10.1.3.0 is directly connected, Loopback2

C       10.1.2.0 is directly connected, Loopback1

C       10.1.1.0 is directly connected, Loopback0

It only shows connected routes. It does not show any routes coming from r2 and r3. I am aware about split horizon as well in this network type. but there is not need to configure that as if now. cz i am not getting routes from any of the spokes to hub router which is R1.

These are some logs whicI got from R3(SPOKE)

R3#

*Mar  1 04:45:15.382: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 25: Neighbor 172.16.124.1 (Serial0/0) is up: new adjacency

IP-EIGRP neighbors for process 25

H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq

                                            (sec)         (ms)       Cnt Num

0   172.16.124.1            Se0/0            163 00:01:11    1  5000  1  0

Hold time is 163 ... I think it should be less then 10. After holtime expire my neighborship goes down.

No access list is configured to block hellos.

So what could be the reason that i am able to see it in neighbor table but routing table is not giving me any eigrp learnt routes.

I think FR router is creating problem. How to fix it...

THANKS IN ADVANCE :-)

Hello Namish,

on spoke routers R2, R3 add the broadcast keyword to the frame-relay mapping command.

This is required to correctly exchange  EIGRP hello packets that have a multicast destination.

On hub router you need to disable EIGRP split horizon also as you noted

Hope to help
