Re: Frame - eigrp and split horizon

Why don't you have a F/R map on the spokes?
Is there any other link between the spokes or hub to spokes?

I set up a hub router on a frame with the following configuration.....

interface Serial0/0
 ip address 192.168.1.1 255.255.255.0
 encapsulation frame-relay
 no ip split-horizon eigrp 100
 frame-relay map ip 192.168.1.1 102
 frame-relay map ip 192.168.1.2 102 broadcast
 frame-relay map ip 192.168.1.3 103 broadcast
 no frame-relay inverse-arp
!
router eigrp 100
 network 192.168.1.0
 no auto-summary

There are two remote sites, with the following configuration.....

interface Serial0/0
 ip address 192.168.1.2 255.255.255.0
 encapsulation frame-relay
 no frame-relay inverse-arp IP 203
 no frame-relay inverse-arp IP 204

and......

interface Serial0
 ip address 192.168.1.3 255.255.255.0
 encapsulation frame-relay
 no frame-relay inverse-arp IP 302
 no frame-relay inverse-arp IP 304

Both set up with eigrp 100. They both form the neighbor relationship
with the hub router. However, there is still not connectivity from
spoke to spoke (even though split horizon is disabled). I know that
everything works if I statically map everything, just trying to
understand a little further on the eigrp between multiple routers. I
was thinking that this may be a recursive issue, but I see that we have
the route recursing to the hub router, but not continuing from the hub
to the second spoke.....

R2#sh ip rou 192.168.1.3
Routing entry for 192.168.1.0/24
  Known via "connected", distance 0, metric 0 (connected, via interface)
  Redistributing via eigrp 100
  Routing Descriptor Blocks:
  * directly connected, via Serial0/0
      Route metric is 0, traffic share count is 1

I may be missing something. Sorry for hitting on some of the more basic
things.
