How to configure MPLS on a 2800

Unanswered Question
Aug 9th, 2007

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The tag-switching commands have been replaced by the "mpls ip" commands.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
