Tunnel keepalives not working after upgrading 2821 to from 12.4 to 15.0
I have a pair of older 2821 routers doing site to site VPN termination. They use HSRP on the external interface, with "tunnel source" mapping to the respective HSRP addresses.
Running 12.4(25)g, a tunnel with the source of an inactive HSRP address would show as "line up, line protocol down". If the router went HSRP active, then the tunnel would change to "line up, line protocol up"
After upgrading to 15.0(1)M10, the tunnels always show up/up regardless of HSRP state. I'm using OSPF to do the routing so OSPF will only come up if the HSRP state and tunnel source match, but this is really weird behavior to me. In a different data center I have a pair of 2921s with similar configuration, and they are correctly marking tunnels up/down if not HSRP active
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
