I have doubts regarding the following scenario:
We have two ASA's 1, 2 (primary, secondary) in the Central site (New York) doing failover (active, standby). The ASA's establish VPN tunnel with about 60 clients. We put a third ASA 3 in another site (Ohio), for use as a Disaster Recovery, if the central site (New York) is inactive. The clients are configured for backup-servers (http://www.cisco.com/en/US/docs/security/asa/asa81/command/ref/b.html#wp1358314), if the central site is down, the clients VPN tunnel established by ASA 3 (Ohio).
My questions: If the ASA primary is down, and the secondary (New York) take active, the clients that are connected in the primary will fall? Connection will be restored? And will that these clients will understand that there was failure and try to establish VPN tunnel with ASA Ohio (backup-server)?
Appreciate any help.
