Is that the solution for Vol2 Ver 3 Lab2 Section 3.2?
My understanding was that a GRE tunnel interface wouldn't go down unless it
didn't have a route for the tunnel destination?
I've accidentally blocked ipv6ip and gre tunnels without causing the
interfaces to fall over. I guess I could use a time-based distribute-list?
I was looking at "ppp idle-timeout" and "ip idle-group" (with a time-based
ACL) but that only seemed to make the interface flap.
