A Chairde,
Am having problems setting up MPLS between a AS5350 and 7609 , I have used commands stated in this link, enable MPLS incrementally on a network.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/switch_c/xcprt4/xcdtagc.pdf
The commands below are added to each router, and some troubleshooting.

ok first things first. Add the command mpls tdp router-id loopback 0 force if you can. Then you must be able to reach the loopbacks of each router i.e. use ospf or something.

Ro,
Thanks for the respone, have been playin, with MPLS for last few hours.
The routing between the loopbacks is now working, can PING 7609 Loopback from AS5350 ,and vice versa. (used static routes).
Having problem with TDP / LDP on routers,
mpls label protocol ldp / tdp command works correctly on both routers, but the
tag-switching tdp router-id Loopback0 force
command works on the 7609, but when I add it onto the AS5350 , the command "mpls ldp router-id Loopback0 force" appears on the startup script.
The opposite is true for the 7609 , you add MPLS LDP command, and TAG-SWITCHING command appears instead.
Any Ideas, as different configs of this leave me with forwarding table with both tags added, but not been able to ping the loopbacks !!!
When I can ping bot loopbacks, the OUTGOING TAG , disapears.....
Problem is LOOPBACK Commands on bot routers default to LDP (AS5350) , or TDP (7609). Any Ideas ...
mpls label protocol tdp
tag-switching tdp router-id Loopback0 force
mpls label protocol tdp
