Default route through a Virtual Tunnel

I need to set up a redundance solution where one ISP uses PPPoE and one static ip adresses. And over there I though of running to tunnels, where I either load balanced or used failover.

But the real problem is that everything needs to go through the tunnel.

Is it possible to do:

int fa0/0

ip add

int tunnel0

ip add

tunnel source fa0/0

tunnel dest

tunnel mode ipsec ipv4

tunnel protection ipsec VTI

ip route

ip route tunnel0

My suggestion is to have ip route after ip route tunnel0. Because always routing is checked from top to bottom . If a match ( First route entry ) is found that interface or ip address is chosen.

Hi thanks for the reply :)

I justed tried to set a default route through a tunnel in a lab.

The tunnel came up, but when it found out that there was an overlapping route it whent down again. So the conclusion is that you can not use a default route through a virtual interface tunnel.
