There are two types of traditional l2vpn, one is point-to-point (VPWS) and the other is point-to-multipoint(VPLS).
For VPLS, EVPN has a corresponding technology PBB-EVPN.
This topic, will intruduction a simple PBB-EVPN configuration.
Refer to the following route types，PBB-EVPN will use Type 2 and Type 3.
