Hi All,
I have a couple of ASA 5520 ( 9.1 version) in A/S failover connected to Core (4500X). We need to configure routing : I have no problem with static routing but when I configure ospf after some seconds the standby goes in active ( though the real active remains active) and I don't know why.
We have a SVI on core side
interface Vlan700
description ASA-LAB
ip address 10.50.50.82 255.255.255.248
ip ospf dead-interval 3
ip ospf hello-interval 1
on ASA side
interface GigabitEthernet1/0
media-type sfp
nameif inside
security-level 100
ip address 10.50.50.81 255.255.255.248 standby 10.50.50.83
ospf hello-interval 1
ospf dead-interval 3
the Standby becomes immediately active after ospf configuration and show failover history, I have:
10:31:10 CET Nov 9 2017
Standby Ready Just Active ACK not received for failover message
10:31:11 CET Nov 9 2017
Just Active Active Drain ACK not received for failover message
10:31:11 CET Nov 9 2017
Active Drain Active Applying Config ACK not received for failover message
10:31:11 CET Nov 9 2017
Active Applying Config Active Config Applied ACK not received for failover message
10:31:11 CET Nov 9 2017
Active Config Applied Active ACK not received for failover message
10:31:27 CET Nov 9 2017
Active Cold Standby Failover state check
10:31:29 CET Nov 9 2017
Cold Standby Sync Config Failover state check
this happens more times until the standby reboots
ASA-LAB#
******REPLICATION OF CONFIGURATION FROM ACTIVE TO STANDBY UNIT IS INCOMPLETE,
TO PREVENT THE STANDBY UNIT TAKING OVER AS ACTIVE WITH A PARTIAL CONFIGURATION,
THE STANDBY UNIT WILL NOW REBOOT*******

*** --- SHUTDOWN NOW ---
Could you please if there is something to know about failover and ospf?
Thanks a lot
Alessandro
