Ooh and forgot to mention very good introductory material is from Cisco live -on demand library: BRKMPL-2333 - E-VPN & PBB-EVPN

I was reading about it and it's supported on 4.3.2
http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-3/lxvpn/configuration/guide/lesc43xbook/lesc43pbb.html#pgfId-1187133

I think I will give it a try :)

BR,
Mohammad

> EVPN is supported only on A9ks as far as I know (on A1k only as AF in BGP for RR functionality).
> By all means I'll go with EVPN for all the new deployments the data-plane scales so much better compared to legacy VPLS.
> Though personally I prefer PBB EVPN because it converges and scales better and find it more straightforward.
> The only problem is these are still pretty new - EVPN got standardised just this year and PBB-EVPN not yet (guess that's one of the reasons Juniper is still holding back on PBB-EVPN) so it needs more brave folks to test and catch all the bugs.
