How to configure MPLS on a 2800

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?

Re: How to configure MPLS on a 2800

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The tag-switching commands have been replaced by the "mpls ip" commands.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

Re: How to configure MPLS on a 2800

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
