Hi,
When i put show mpls traffic-eng topology command i see reservation only on outgoing interfaces of the router. Why? Why not the incoming interfaces?

Link 1 reservation is there but on link 0 NO RESERVATION. Why? Since link 0 is incoming interface and Link 1 is outgoing interface.of the tunnel.

Hi Ankur,
That is because MPLS TE Tunnels are unidirectional.
So they are setup only in one direction from source to destination.
Consequently the resources reserved for a particular tunnel are reserved in one direction only.
So you might want to setup a tunnel in the opposite direction as well.
