VPLS Features

How does an H-VPLS lessen the full-mesh requirement in a VPLS?

  • A It uses only spoke SDPs to connect the core network and to connect to the MDU.
  • B It uses spoke SDPs to connect the core network, and mesh SDPs to connect to the MDU.
  • C It uses mesh SDPs to connect the core network, and spoke SDPs to connect to the MDU.
  • D It uses spoke SDPs to connect within a metro VPLS, and mesh SDPs to connect the two or more metro VPLS together.
Explanation

H-VPLS scales VPLS by keeping PEs fully meshed within each metro VPLS domain and using point-to-point spoke SDPs to interconnect the metro domains. This eliminates the need for a single full mesh among all PEs across the combined network.
