MPLS interface

Answered Question
May 31st, 2008

is there any way to configure the router to show the host name instead of the ip address on MPLS connection? like when you do show ip bgp neigh to see neighbor host name.it possible to see on frame-relay or T1 but not MPLS. I'm new for MPLS. any help!!! thanks in advance!!

Elias,

What i meant from my initial reply was that there is no extra requirements with MPLS on CE side, thus nothing should be different between having MPLS or Frame-Relay service from the CE prospective. As for your query AFAIK this is possible for OSPF (using the "ip ospf name-lookup" command) and also built in within ISIS (Dynamic Hostname TLV (type 137) which can be disabled via the "no hostname dynamic" command), but for BGP i don't know, but sometimes i play with regexp to get similar output, ex: "show ip bgp ne | i Desc|nei|state|Pref", this should be useful if you have added description per neighbor.

BR,

Mohammed Mahmoud.

sh ip bgp

*> 10.30.133.0/24 10.50.254.91 0 1803 65137 i

*> 10.40.148.0/24 10.50.254.91 0 1803 65102 i

*> 10.52.0.0/19 10.50.254.91 0 1803 65176 i

so the network address on the left is my routers on other locations.let say when one of my router is down.here my question I want to identify the router by it's host name instead of the network number.easily to track down the router.

sorry for the confusion.

Hi Elias,

Kindly correct me if i am wrong, i have the feeling that you are talking about a CE, and generally a CE router is not MPLS aware and it shouldn't have any special requirements.

on my main core router for MPLS.

when do show ip interface summary or show ip bgp neigh. I see all the interfaces for my mpls connection. but the connections show the ip address for all neighbor ip address.

my question is is there possibility to configuration to setup to able to see the host name of the neighbor instead of just the ip address.

Thanks
