Frame Relay, RIP & Split Horizon lab exercise issue... 1

[admoore]

I am having issues with RIP updates while attempting a training lab concerning Frame Relay and split-horizon...

Basic setup is:

show ip route on r1 shows no RIP routes; and, debug ip rip on R2 reports:

*Mar  1 18:48:31.487: RIP: sending v2 update to 224.0.0.9 via Loopback0 (2.2.2.2)
*Mar  1 18:48:31.487: RIP: build update entries - suppressing null update

Any suggestions welcome... I have tried this setup several times with the same result...

R1 is a 2500 (also my terminal server)
R2 & R3 are 2610XM's as is the final router which is set up to emulate the frame-relay cloud...

TIA,

-A

Oops... My bad... Helps when you don't forget to put an ip address on R2's s0/0...

BUT,

I am still not getting R2's loopback (or any other route) in R1's rip routing table...

?

So your configuration will not have an issue with split-horizon due to the fact that you are using point-to-point sub interfaces. If you were using multi-point and had all serial interfaces on a common subnet then you would run into issues with split-horizon.

As for the routing issues, you should post your configurations from all three routers.

Sorry for taking so long to re-post (work interfered)...

Anyway, I expected to see a route to R2's loopback address (2.2.2.2) show up on R1 & R3; but, I see it on neither... In fact, R1 shows no RIP routes...

2509_T-SERVE#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is 10.10.10.1 to network 0.0.0.0

     172.12.0.0/30 is subnetted, 2 subnets
C       172.12.123.0 is directly connected, Serial0.12
C       172.12.123.4 is directly connected, Serial0.13
     9.0.0.0/32 is subnetted, 1 subnets
C       9.9.9.9 is directly connected, Loopback99
     10.0.0.0/29 is subnetted, 1 subnets
C       10.10.10.0 is directly connected, Ethernet0
S*   0.0.0.0/0 [254/0] via 10.10.10.1

I can't ping across any of the links, either...

Any ideas what I might have done wrong?

All of the frame maps come up ok...

first thing, remove all of your frame-relay route statements on your FR switch. Since you are doing point-to-point links you should have the following:

DLCI 111 = R1
DLCI 222 = R2
DLCI 333 = R3

Frame Switch

interface s1/0
  description To R1
  frame-relay route 222 interface s1/1 111
  frame-relay route 333 interface s1/2 111

interface s1/1
  description To R2
  frame-relay route 111 interface s1/0 222

interface s1/2
  description To R3
  frame-relay route 111 interface s1/0 333

R1

interface Serial0.12 point-to-point 
 ip address 172.12.123.1 255.255.255.252 
 no ip route-cache 
 frame-relay interface-dlci 222

interface Serial0.13 point-to-point 
 ip address 172.12.123.5 255.255.255.252 
 no ip route-cache 
 frame-relay interface-dlci 333

R2

interface Serial0/0 
 ip address 172.12.123.2 255.255.255.252 
 encapsulation frame-relay 
 frame-relay map ip 172.12.123.1 111 broadcast 
 no frame-relay inverse-arp 
 frame-relay lmi-type cisco

R3

interface Serial0/0 
 ip address 172.12.123.6 255.255.255.252 
 encapsulation frame-relay 
 frame-relay map ip 172.12.123.5 111 broadcast
 no frame-relay inverse-arp 
 frame-relay lmi-type cisco

This should get your FR PVCs up and running.
