For L2VPN if you could make it work - go with EVPN day 1, it solves most of=
the issues present in both LDP and BGP VPLS implementations.
Be aware of differences in PBB vs plain EVPN and platform support.=20
EVPN, specifically multhoming/split horizon/some other stuff as well as pre=
sence of L3 (type 2/5) and complications of above brings lots of complexity=
into fast path processing and not every platform/NPU can do full spec.
