Re: MPLS TE router-id

Hi,

I searched the Cisco site and found this:

http://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_te_expl_address.html
..........................

tunnel destination ip-address
Example:

Router(config-if)# tunnel destination 10.11.11.11
        

Specifies the destination for a tunnel.

The destination of the tunnel must be the MPLS traffic engineering
router ID of the destination device.

-----------------------------

So in your example you could change the mpls traffic-eng router-id to
lo1 on R3 and it would work. The R1 tunnel source ip address could be
either lo0 or lo1.
