It seems to be that the EIGRP packets are sent out, but then never
acknowledged. What concerns me is that in the TCP/IP bible for the ccie's,
there is a reference to the exact problem on pg 392. They say that the
packets are being filtered. I know that the otherside router has access
lists, attached below, but that is for the redistribution into the other
process. I can't see that being an issue as there is no access list applied
to the physical token ring port.
Other router:
router eigrp 1997
redistribute ospf 100
passive-interface Serial0
passive-interface Serial0.1
passive-interface Serial0.2
passive-interface Serial0.1111
passive-interface Serial1
network 10.0.0.0 ( Our network)
default-metric 256 2000 255 255 1000
distribute-list 11 out ospf 100

!
router ospf 100
summary-address 10.60.0.0 255.255.0.0
redistribute eigrp 1997 metric 1000 metric-type 1 subnets

Andrew,
What IOS version are you running on ?
Do you have any other Routers on any other Token Ring
segments ?
I believe that major surgery was implemented in IOS
11.3 for EIGRP not sure how that would effect Token
Ring though.
Have you analysed the Token Ring Segment for errors
e.g beaconing etc ?
It is possible that some external event is causing a
Ring purge every 2 minutes and stopping the EIGRP
multicast packets getting through thus, losing your
neighbor relationship.
HTH
Phil.
