Re: MPLS VPN - difficulties in last level trouble shooting

Experts,

*can you plz let me know why i am unable to achive the below PING tasks*

Configured the following command on the PE-P connected interfaces.
on Routers R4, R4, R5 routers.
mpls ip
mpls label protocol ldp
mpls ldp advertise-labels

*Currently i'm Unbale to ping from below PE routers to CE routers -*

*R3 #ping vrf CustB 172.31.8.1 ( Router8 Lo ip , belongs to CustB VRF)....0%
success rate*
 R3 #ping vrf CustB 172.31.1.1 ( Router1 Lo ip , belongs to CustB VRF)..100%
success rate

 *R5 #ping vrf CustA 172.31.7.1 ( Router7 Lo ip, belongs to CustA VRF)..0%
success rate.*
R5 #ping vrf CustA 172.31.2.1 ( Router2 Lo ip, belongs to CustA VRF)...100%
success rate

R1 , R8 are belong to VRF CustB CE routers. ( ips are 172.31.1 /172.32.8.1)
R2, R7 are belongs to VRF CustA CE routers. ( ips are 172.31.2.1 /172.31.7.1
)

Appreciate your response on this.

Thanks ,
Mirza.
