[c-nsp] l2vpn vpls w/bgp autodiscovery - me3600x to asr9k

Aaron aaron1 at gvtc.com
Sat Jan 5 17:50:55 EST 2013 

This is my first time trying to get l2vpn vpls w/bgp autodiscovery to
work.please help if you know a simply scenario config that you could share
to make it work with ios xr on one side and me3600x ios vanilla on the other
side.

 

Trying to get it up between 3 PE nodes where I will run vpls between all 3.
2 are me3600's and 1 is asr9k.  I would like the asr9k to be
route-reflector.

 

I tried and tried first just to get it up between asr9k and one me3600
first..initially l2vpn address family bgp neighbor session came up and
stayed up.this was ONLY after putting in the bgp neighbor and AF configs
under bgp.

 

BUT, once I added some l2vpn, vfi stuff on asr9k OR l2 vfi xyz auto, vpn-id
stuff on me3600, it all fell apart.

 

It went through a few iterations of trying various things..during that time
I saw several errors on either side.. Here are some of them incase they look
familiar to you. 

 

Thanks, Aaron
