On a 28xx router, say if I have 2 links. On normal operations, i want to send all PC traffic via link A (not encrypted) and all AS 400 traffic via link B (IPSec).
Now my question is when do the router check the IPSec? i.e. say if the primary link failed, can i now direct all traffic to go via the secondary IPSec tunnel as well?
I was thinking to use policy routing + normal routing... so policy route all traffic (except AS400) to primary link, with normal routing pointing thru IPSec tunnel. Hence if the primary link fails, the normal routing will pick all traffic and pass them towards IPSec tunnel.
But this only works if IPSec only checks on the outgoing interface it applies to. Is this the case?
