[j-nsp] IOS-JUNOS VPLS LDP BGP auto-discovery interop

[Ihsan Junaidi Ibrahim]

Hi folks,

Anyone can help if I'm missing anything?

I have a BGP session setup between two ME3600X (IOS 15.2) PEs with JUNOS 10.4R4.5 M120 RR exchanging L2VPN VPLS auto-discovery AFI.

The session is well established and prefixes are received however the peers are unable to locate each other hence the VPLS circuit is not created.

Peering the two Cisco PEs together resulting a working VPLS connectivity.

Ditto when peering the PEs with and ASR1K/9K acting as an interim RR.

Here's the BGP neighbour output on the M120.
