I am planning to set up a branch office (6 offices) with one primary and one DRsite. I have ASA 5510 and cisco 2921 in primary and DR SITE .CISCO 892 in branch ofices. MPLS VPN over t1 connection connect to ASA 5510. IPSEC VPN over ISDN connet to CISCO 2921. Both ASA 5510 and CISCO 2921 should be able to do intervlan routing for primary and DR sites.
Whenerver MPLS VPN fails ,IPSEC VPN should automaticaly work.
Can this be done? what other devices need? There should be IPSEC VPN connetions from remote branches to both primary and DR sites so that one fails other should work.
Thank you
