Aaron,
L2VPN context is the new L2VPN protocol based CLI.
http://www.cisco.com/en/US/partner/docs/switches/metro/me3600x_3800x/software/release/15.3_2_S/configuration/guide/swl2vpn_prot_based.html

L2VPN VFI is the legacy CLI.

Subject: Re: [c-nsp] BGP Signalled VPLS

Thanks Nick,

Yeah I recall using no rd and no route targets with a vpls w/bd ad and ldp
sig.... must have all worked with some automagic rd and rt thingy's

Also my version of me3600 ios doesn't have bgp signaling possible, only ldp.
I think a previous poster (waris maybe) mentioned that 15.3(2)S or something
like that was required for bgp sig and that cisco is making a move towards
more support for bgp sig.

I was just exploring some of this in my me3600 with 15.2(4)S1....

What is the difference in the 2 following things... ?  l2 vfi and l2vpn
context vfi ?

Switch(config)#l2 vfi ?
  WORD  VFI name

Switch(config)#l2vpn vfi context vfi ?
  <cr>

Why would I use one over the other?

Aaron

Had a call with cisco tac and they managed to get it working by removing the
RD.

No idea why this resolved it.  Now to try and get it to working with a
juniper PE.

Hi,

I have 2 x ME3600x running me360x-universalk9-mz.153-2.S and am looking
to use the new VPLS BGP signalling functionality.

I am using RSVP with the topology attached but I cannot get traffic to
pass.  Any ideas?


Configs as below.

Any help with debug commands would also be greatly appreciated.
