It may very well be that VPLS days are numbered and EVPN is to blame. Nevertheless, it would be naive to expect VPLS extinction in the near future. With all its shortcomings VPLS is still very well standardized, interop-proven and has a huge footprint in MPLS networks of various scale.

In this post I will cover theory and configuration parts for one particular flavor of VPLS signalling — BGP VPLS (aka Kompella VPLS) defined in RFC4761. I’ll start with simple single home VPLS scenario while multi-homing techniques and some advanced configurations will appear in separate post later.

In this topic the following SW releases were used:
