VPLS Multi-Homing Application

VPLS Multi-Homing Application

On VPLS networks, carriers usually dual-home CE1 to PE1 and PE2 through redundant links to deliver high-reliability services. To prevent routing loops caused by link redundancy, VPLS multi-homing can be configured on PE1 and PE2.

Figure 10-41 VPLS multi-homing networking

On the network shown in Figure 10-41, an MPLS backbone network is deployed to provide VPLS services for enterprise users. CE1 is single-homed to PE1, CE2 is dual-homed to PE1 and PE2, and CE3 is single-homed to PE3. VPLS multi-homing can be configured so that PE1 and PE2 will assign the same multi-homing site ID to CE2. A preferred PE is then selected for PW establishment. PE1, PE2, and PE3 can establish PWs between each other to allow communication between CE1, CE2, and CE3.

Feature Deployment
  • Deploy IP and an IGP on the carrier network to ensure reachability between the PEs and Ps at the network layer.
  • Deploy MPLS on the carrier network and establish LDP LSPs or TE LSPs between the PEs.
  • Deploy BGP between the PEs.
  • Deploy VPLS on the PEs, create a VSI for each user, and bind a user-side interface to the L2VPN.
  • Allow each PE to assign a site and priority to each CE.
