Description (partial)

EIGRP routes on the active ASA getting deleted after the ASA failover. The ASA running version 9.1.3.  
The EIGRP routes get deleted after 60-65 seconds of the failover with the following debug message (when 'debug route ha' is configured on the ASA).

ROUTE HA: Reconvergence Timer expired, flushing out stale routes.
ROUTE HA: Flush Stale Entries from RIB
ROUTE HA: delete route to x.x.x.x  y.y.z.z
ROUTE HA: delete route to a.b.c.d y.y.z.z

Two ASA's in Active/Standby failover pair running v9.1.3. The router connected to the ASA configured in such a way where both  'ip summary-address' and routers interface subnets are configured in the same classless subnet on the router.

E.g.-  Command 'ip summary-address eigrp 100' and 'ip summary-address eigrp 100'configured on the router, when the router is already configured with interfaces in subnet 10.100.255.x/29 and  10.102.255.x/29.

After the fail-over from an ASA to the other ASA,  EIGRP routes on active ASA get deleted.
