Sara,
I had a similar problem on a production network. Hub router was
running 11.2.5, with multipoint subint. Only formed 1-way neighbors with
spokes, even though I had the timers matching. Upgrading to a later 12.0
release on hub fixed it. I almost think the 11.2 code was ignoring my timer
changes. 'sh ip eig timers' should show you what the timers are counting
down from.

Subject: bootcamp lab 2 problem eigrp won't form neighbor
Hi group, I am trying the lab 2. I encountered a eigrp problem. R1
configured with sub-interface s0.1 point-to-point, and s0.2 multipoint.
S0.1 is running eigrp with R2, S0.2 is running ospf with R3 and R5. with
the config as following, R2 is able to form eigrp neighbor with R1, but
R1 can't form neighbor with R2. when i debug eigrp packets, I have this
error message IP-EIGRP: Neighbor <neighbor IP address> not on common
subnet for <interface>. I tried to ajust the hello and holdtimer for
eigrp on both R1 and R2 related interface to 60 and 180 respectively, but
it does not help. did I missout something? Pls help.when I try to put
both R1 and R2 on major interface, they then form neighbor. R1 conf
