28 H-VPLS Commands
H-VPLS (Hierarchical Virtual Private LAN Services defines an architectural bridging model for
interconnecting multiple Ethernet LAN segments over a service provider MPLS network. Unlike VPLS,
which requires a full mesh of Virtual Circuits (VCs), H-VPLS specifies a hierarchical architecture to
extend spoke VCs to the service provider's network edge. The H-VPLS bridging model is based on
standard 802.1D bridging concepts. By implementing standard bridging technology, a protocol agnostic
L2 VPN architecture can be implemented independent of the underlying MPLS IP metro core.
