LDP based CSC VPN - ASR9k/IOS-XR 4.3.4

Hi All,

I am trying to configure CSC MPLS VPN on IOS-XR 4.3.4 on ASR 9K as PE. Currently the configuration is on NPE-G2 and NPE-G1 as PE routers. 

LDP is configured between PE and CE for label exchange and OSPF is the protocol between PE and CE.

When I try to configure LDP between ASR9K and CPE, I am not getting LDP as the option between PE and CE, I am not getting any option of specifying LDP  under the VRF.

Even the IOS-XR MPLS config guide only talks about BGP based label exchange between PE and CE on IOS-XR.

I would like to confirm, can LDP be configured under VRF in ASR9K as PE or BGP is the only option available?

thanks in advance
Arun

Got the answer from Cisco NSP mailing list.

 

CSC VPN on MPLS LDP is available only from IOS-XR 5.1.1
