I am implementing an MPLS network on 2800 platforms. I am having issues with the configuration. I am trying to enter the 'ip cef distributed' command and it won't take the distributed sub-command. Also when I try to enter the 'tag-switching ip' command it isn't recognizing the gobal or interface command. I am running SP services 12.4(13d). Is there something else I need to configure to enable MPLS?

The 2800 series is not a distributed processor platform. It has one processor and therefore can not run CEF distributed.
The tag-switching commands have been replaced by the "mpls ip" commands. I can't remember when this happened, but it's been a while.

There seem to be many options for configuring MPLS on the routers. I have a 3845 core router with a multlink interface connected to the MPLS network. I have 3 remote offices with T1s connected into the MPLS network. Which option would work best for that scenario?
Option 1
3845 core router
ip cef
tag-switching ip
interface multilink 1
tag-switching ip
remote router
ip cef
tag-switching ip
interface se0/0/0
tag-switching ip
Option 2
3845 core router
ip cef
mpls ldp label protocol ldp
interface multilink 1
mpls ip
remote router
ip cef
mpls ldp label protocol ldp
interface se0/0/0
mpls ip
option 3
3845 core router
interface multilink 1
xconnect peer-router-id vcid encapsulation mpls
remote router
interface se0/0/0
xconnect peer-router-id vcid encapsulation mpls
Thanks,
Steve
