Cisco ASA HA

Hi,

       i have 2 questions on ASA HA:

        1- when fail-over happens in Cisco  ASA HA  , does the ip addresss of interfaces on primary unit goes to secondary unit???

 

        2- if i will configure ospf on ASA with router , which ip address (primary or secondary ) should i configure on router to establish OSPF neighbourship with ASA??

Re: Cisco ASA HA

Hi,

When an ASA is configured in HA (Active/Standby), upon failover the Standby ASA inherits the IP addressing from the Primary ASA.

 

A OSPF adjacency is only established with the current Active ASA, there would be no adjacency with the Standby ASA - until failover occurs.

Re: Cisco ASA HA

thank you for your reply , so that means the standby gets the ip address of primary device and the primary gets the ip address of standby device when fail-over happens.

Re: Cisco ASA HA

The Primary-Standby will get data interface addresses of the former Secondary-Standby after failover if the interface configurations had standby addresses configured. However those are not required, so the behavior depends on how you had it configured.

Any configured management address will remain associated with a given physical appliance, no matter the HA status.
