Two 2811 routers, both on 12.4(13r)T5 software.
Each has a VTI interace. VTI works great, i'm running ospf across it which also is working well. My problem is that if i shut down the ethernet interface (through software or unplugging) on router A, the tunnel interface on router B remains in up/up state. Even after a period of 30 minutes. Router B can't ping or pass any traffic across the tunnel, but it's still up/up. This causes a problem with ospf routing updates and some static floating routes.
Is there a timer or something to force the tunnel go to up/down or down/down after X seconds withotu activity? I'm already using ospf dead-timers to get my routing updates to work, but sine router B always thinks the tunnel is up...it continues to pass traffic over the downed tunnel interface wich ends up in a black hole.
