[c-nsp] EIGRP routing failure

[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...
