Re: basic mpls config

you know i was going to answer www.cisco.com and RTFM but here ya go im feeling happy this morning.

Each router

ip cef

mpls ldp label protocol ldp

mpls ldp router-id loopback 0

int lo0

ip address MUST BE A /32 address

on each interface thereafter

mpls ip

job done

to test? show mpls ldp neighbor, show mpls forwarding.

If you want to test PE functionality then i do suggest www.cisco.com ;-)

Re: basic mpls config

Hi,

just a small clarification of Robs post:

It should say: www.cisco.com/go/mpls and then RTFM

:-)

Also traceroute and show ip cef detail will allow you to see labels and their usage.

On the interfaces "mpls mtu 1512" will avoid MTU problems.

And one more remark: do not get scared by the router if it is translating your "mpls ip" into "tag-switching ip". This is normal and does not do any harm. The meaning and function of the two commands are the same.

Hope this helps! Regards, Martin
