It appears this has been brought up before, but it was never resolved.
Currently I have an ASA 5510 connected to our distribution layer using an IP address in a subnet protected with HSRP. If one of the two dist layer devices go down, the firewall is protected and the IP address doesn't change.
Because of stability and bandwidth requirements, the firewall is being upgraded to a 5520 and connected directly to our cores using EIGRP to route and load balance traffic. I cannot create a loopback address and will need to bind the VPN connections to one of the two point to points with the cores.
If that core router were to go down for some reason, albeit be maintenance or software/hardware issue, the VPN will also go down.
Is there anyway to create a loopback address or use the redundant interface command to create such a link?
Thanks in advance.
