Dear stephtchoko,

MPLS is a great technologies it’s easy to take and running script from the internet and post it on your router then everything gone be working but it’s very nice to understand how it’s working because your life gone be under control (I mean you have to understand the technologies how it’s works to troubleshoot your network in any case)

Here is a simple configuration to get mpls working with 2 routers

Topology: Router1 Serial0 connected with Router2 via Serial2

Router1 S0/0  Router2 S0/0

((Router1))

Router1(config)# ip cef

Router1(config)# mpls label protocol tdp

Router1(config)# tag-switching tdp router-id serial0/0

Router1(config)# mpls ldp logging neighbor-changes

interface Serial0/0

ip address 172.16.1.1 255.255.255.252

no shut

tag-switching ip

((Router2))

Router2(config)# ip cef

Router2(config)# mpls label protocol tdp

Router2(config)# tag-switching tdp router-id serial0/0

Router2(config)# mpls ldp logging neighbor-changes

interface Serial0/0

ip address 172.16.1.2 255.255.255.252

no shut

tag-switching ip

please be informed that you have to use any routing protocol to start advertise the L3 information.

the document is good, but is everything working with you or you facing a problem?

yes, ThanK.This is my first experience with this protocol (MPLS).Which type of routing protocol ( isis, ospf) do you think, it is more adapatable with mpls in isp network ?

ISIS is recommended in service provider networks and it's more sclabel than OSPF

stephtchoko Thu, 11/03/2005 - 23:00

please what is main reason isis is more scalable than ospf ?

Best regards.

Here's a copy of the configuration that I had on my two lab PE routers that was testing multicast tunneling through mpls. You will need two CE routers for a total of four routers. It's not a perfect config (the traffic engineering is only half begun) but it will get you going.
