I found 2 local router's eigrp neighbor resets at same time one per serial port(there are only this 2 serial ports on the router running eigrp)
The debug display at local is DUAL-NBRCHG.........summary...remove external
the debug display at remote neighbor is DUAL-NBRCHG.........reset
Local router's ethernet port belongs to OSPF and I have redistribute routes from ospf to eigrp.I found that when one of local directly connect OSPF link unnormal and the ospf adjancy resets, two EIGRP neighbor resets!
What the reason for EIGRP neighbor resets and how to avoid ospf's instability affect EIGRP neighbor adjancy?
thanks for any reply.
