I have a situation where I have a main site that has a 6506-E switch and a remote site that has a 1841 router. I am wanting to do some redundancy for these two sites, and I thought I put an ASA with a site to site vpn at each site, where they go out to the Internet for a second connection. They currently have an MPLS circuit where the two sites exchange traffic,and all Internet traffic goes out each sites own Internet connection. Im wanting to do some redudancy, and I was wondering if I should do a routing protocol like eigrp across the MPLS for the two, and have a static backup route pointing to the ASAs so that if the MPLS goes down, traffic could fail over to the ASAs and go across the vpn that was created. Anyone done anything like this? If so, how would I proceed to do something like this? Any help appreciated.
