I trying to configure MPLS TE on 6500's. I have a layer 3 port channel configured between two switches. I am bundling two links. I had issues giving this command on a layer 3 port channel (mpls traffic-eng tunnels). Do I need to use layer 2 port channel instead? That way it allowed me to enable that command on SVI. I guess, we cannot configure TE tunnel between switches using different interfaces such as layer 3 port channel. Any suggestions please post.
