Cisco ASA Failover 5 ISP Connections?
Posted on 2012-09-06
I have a pair of Cisco ASA 5510's setup in Active/Standby mode.
At the main office there are 5 ISP connections. They are used as follows.
ISP 1 - Internet
ISP 2 - SAN Replication
ISP 3 - VPN for remote staff
ISP 4 - Multiple bonded MPLS T1's for branch access (Terminal services and IP phones)
ISP 5 - 4G Internet (Not currently used)
Can i have each ISP connection failover to the ISP of my choosing? For example, I want ISP 1 to failover to ISP 2, and if ISP 2 is down then have ISP1 failover to ISP 5.
Can a failover link be active while waiting for failover? For example, can ISP 2 be active for SAN replication while it is waiting for ISP 1 to fail and if ISP 1 fails I don't want it to interrupt the current activity on ISP 2.
