Re: mapping traffic to TE tunnel in Cisco router

The alternatives I know of:

Static routing.

OR

Use autoroute and the tunnel will carry all traffic to destinations
near its endpoint.

OR

Use Policy Based Routing. Note that PBR only "sees" IP packets,
not MPLS frames, so you have to use it on a PE router.

Thought: one might use BGP and route maps to set the next hop
for selected destinations
to a special loopback on the exit router. Then static route to
the special loopback via the TE tunnel. (Is this better performing
that PBR? One suspects so.)
