Re: Traffic Engineering Database and OSPF Database

Hey Buddy

Ok, I think i got your question. There are several options to forward the
traffic down the TE tunnels.

1) Static Routes : pretty simple to point the routes to the tunnels.

2) Policy Based routing : Same that we use in normal PBR. The next hop in
this case will be tunnels.

3) autoroute announce : What this does is any route behind the TE tunnel
Tailend will be reachable through the tunnel. The IGP will run its normal
SPF until it finds a node that is either TE tunnel tailend or located
behind TE Tunnel. In that case it will install the route in the routing
table with the next hop as TE tunnel.

The details of how SPF does this is provided in the book written by Ajay
Simha chapter " Forwarding traffic down tunnels."
