Re: [c-nsp] EIGRP routing failure

2008-10-21 Thread Derick Winkworth 
What do you mean?  The giant counter is incrementing or not?

We ran into an issue where the MTUs were not equal and this was causing
EIGRP to bounce.  The router with the higher MTU was running 12.4 and
the router with the lower MTU was running 12.2, and this was causing the
router on 12.2 to discard the EIGRP packets as giants.   In the logs
it looked as though they are bouncing...

Re: [c-nsp] EIGRP routing failure

2008-10-18 Thread Greg Wendel 
If you are running older IOS code the K value mismatch could be the router
misinterpreting the goodbye message sent by EIGRP.
Hope this helps.

Router#show ip protocols

Routing Protocol is eigrp 100 100
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Default networks flagged in outgoing updates
  Default networks accepted from incoming updates
  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0 =
K-Values
  EIGRP maximum hopcount 100
  EIGRP maximum metric variance 1
  Redistributing: eigrp 100 100
  EIGRP NSF-aware route hold timer is 240s
  Automatic network summarization is in effect
