I am in the process of setting up a lab that consists of an MPLS cloud. Within the lab design, I want to be able to connect to the CE, via telnet, from the PE.
I have successfully been able to do this on one "end" of the MPLS/VPN, however I am having difficulty on the other "end". Logic would dictate that I would copy the config from the working connection, change the ip addresses and be done with it. Unfortunately this is not the case.
Additionally, on the working PE-CE connection, the PE is a 2611 running Version 12.3(26) and on the non-working PE-CE connection the PE is a 3640 running Version 12.3(11)YZ2.
Attached are the configurations. Any assistance would be greatly appreciated.
I forgot to add the config for the not working connection.
Here is the config"
ip vrf vpn-mtb
route-target export 1:100
route-target import 1:100
no ip domain lookup

I would actually like to get to the CE from anywhere on the MPLS network. It seems as though the telnet command would only be a local connection, one that I would have to login to the adjacent PE router first, correct?
I have the following network design already in place. (If you have any suggestions on a better design, please let me know.)
I am running OSPF within the MPLS backbone.
I am then running BGP between the CE's and PE's. Routing, and subsequently telnet, was working fine before I enabled the vrf forwarding on the interfaces. As a matter of fact, I can use the command telnet 126.96.36.199 /vrf vpn-mtb and it works just fine.
You can use this command from any PE where that specific VRF is configured. This would be your best option as you generally don't want to exchange information between the VRF and the global unless you really need to.
