Is it resetting the neighbors on the other subinterfaces of the same interface? Or is it resetting completely? Or (?).... Do you have autosummarization on or off, and is there a summary address involved someplace? Could you post the before and after config just for the interfaces involved, and the log messages you are seeing?

:-)

rgds,

It's not the configuration we need here, but rather the console message stating what happens when the neighbor relationship resets. Do you have eigrp log neighbor changes on or off? It should be on, based on the above configuration. If that's so, what's the message on the console on this router and its neighbor when the relationship resets?
