Description (partial)

The ASA may end up with a route stuck in its routing table after an EIGRP peer disconnects from the ASA.

asa# show route
Gateway of last resort is to network

C is directly connected, outside
C is directly connected, inside
D*EX [170/28416] via, 0:00:09

This only seems to affect EIGRP.

It was primarily observed after changing the IP address of the ASA without resetting the EIGRP peers.
