Hi,
Pls check two things
1.In the remote PE , see wheter you are able to learn the route of the VRF ABCD connected interface of the router from where you ping . ( Check under your address family ipv4 vrf ABCD , wheter redistribute connected given )
2.If the destination is customer end , check wheter you are learning the route of the connected interface .
If both are fine , check wheter labels are exchanged properly at both sides
Hope this helps

See
the router from which I ping is not directly connected with the device I ping..
My Router--ds3 link---->another router---E1 link (172.30.101.58/30)--> router I ping (It is Customer end)
And from My router I am doing ping to 172.30.101.58.
this is the scenario
if need more information kindly tell me
Kindly guide

Hi,
To make it clear ,
In " my router " , you will have a vrf ABCD enabled interface right , Pls check wheter that connected interface route is learned in "another router " , bcause a vrf ping would take , the connected ip of "my router " as source . Similary check for the routing in the CE also for the connected interface ip of " my router "
Hope this helps

see,
from my router i can telnet to another router and from that router i am able to telnet to CE .. But from my router i am not able to reach to CE.
------------------------------------------
My router Config:
ip vrf ABCD
rd 9730:85
route-target export 9730:51
route-target export 9730:92
route-target import 9730:52
route-target import 9730:53
route-target import 9730:92
address-family ipv4 vrf ABCD
redistribute connected
redistribute static
no auto-summary
no synchronization
exit-address-family
---------------------------------------------
Another router config:
ip vrf ABCD
rd 9730:85
route-target export 9730:51
route-target export 9730:92
route-target import 9730:52
route-target import 9730:53
route-target import 9730:92
address-family ipv4 vrf ABCD
redistribute connected
redistribute static
no auto-summary
no synchronization
exit-address-family
and there is no any static route defined in any of two router.
Pl. guide

Dear Vanesh,
TEll me one thing if a vrf is configure in two router ..and both have identical configuration regarding to that VRF. what else is needed to reach to CE (which is connected to another router) from my router
I think i am missing something in config that's why not able to locate the problem
Hope this will useful to u to solve my problem

Mahesh,
are you sure you don't need:
ping vrf ABCD 'CE' source 'one of your ABCD i/f'
??
it should work if you specify source since this is vrf-specific ping.

Hi Mahesh,
Can you confirm that in ur core mpls ip propagate-ttl is configured or not

It is by default enabled and it is in our compan's policy to keep it as default

Hi,
Pls check
1.Whether from "another router " you are able to ping the ip
2.If you are able to ping , check wheter the customer is having default route or some specific routes
3.If default route , then need to check in terms of labels , if static route then check wheter the connected route of "my router " is added at cpe end .

--Ya from another router i am able to ping
-- customer is able to learn route to another router via OSPF
CE: Routing entry for 172.30.6.0/24
Known via "ospf 100", distance 110, metric 20, type extern 2, forward metric 150

Hi
Its simple , I think you are running OSPF between your PE and CE . Do a redistribution of the BGP routes in the ABCD VRF into OSPF
configured for the customer .
It would make the customer routers to learn the routes
Router1(config)# router ospf 2 vrf v1
Router1(config-if)# log-adjacency-changes
Router1(config-if)# redistribute bgp 1 subnets
Hope this helps

isn't there any other way instead of configuring sham links?
where should i configure on CE or PE..B'se on PE I have no config related to OSPF.
