Hi Alexander, Thanks for the information. BTW have you ever used BIRD's BGP/MPLS functionality? It will be really great if you can share me usage details (i.e. any documentation) for the same.

Hi Alexander, Can you please provide me with a configuration example for the below topology. Let say, I want to establish a VPN between CE1 and CE2 through PE1 and PE2. CE1 --- PE1 ---- PE2 --- CE2 1. How to define a VPN say VPN1? 2. How to bind the VPN to CE connecting interface on the PE? 3. How to establish MPLS tunnel between PE’s? 4. Is BIRD support NETCONF/ReST servers? Whether the configuration can be pushed using NETCONF/ReST client? If not then what approach we can use to push configuration via a different process?

BTW have you ever used BIRD’s BGP/MPLS functionality? It will be really great if you can share me usage details (i.e. any documentation) for the same. Yes, we are using more or less the same version in production. As I said before, examples of using it w.r.t to VPN features: http://bird.mpls.in/projects/mpls-bird/wiki/Bird_rr The rest remains the same as in stock bird. It is not exactly "documentation" - feel free to ask any questions :) Thanks Vikram From: Alexander V.
