Configuring LDP HVPLS
Pre-configuration Task
If there are a large number of VPLS PEs, you can use the HVPLS networking scheme to reduce the performance requirements on PEs.
Before configuring
LDP HVPLS, complete the following tasks: 
- Configure LSR IDs on the UPE and SPE.
- Enable MPLS and MPLS LDP on the UPE and SPE.
- Enable MPLS L2VPN on the UPE and SPE.
Kompella VPLS uses BGP as the signaling. Configuring an RR can solve the problem of excessive connections caused by VPLS full connections. Therefore, the switch supports only Martini HVPLS.
