2 cisco firewall and 2 internet ISP

[phung.hoang]

Dear ,

My company has 2 cisco firewalls ISA3000, 2 switches IE2000  and we have 2 WAN lines to Corporate HQ. 

the request is once the primary link goes down the other is backup to take over.

Can someone help to advise how can I configure to meet the requirement?

Your feedback is highly appreciated.

Thanks,

Phung

Hi,

You can use IP SLA on the ASA to track the primary link, if that fails the default route can failover to the backup link. Reference guide here.

Hi RJI,

Thanks for your reply. My issue is I have 2 ASA Firewalls, each has 1 interface connected to 1 WAN link. Can we use IP SLA for this case?

Thanks,
Phung
