8.6. Interoperability with Single-Homing PEs

8.6. Interoperability with Single-Homing PEs​

Let's refer to PEs that only support single-homed CE devices as single-homing PEs. For single-homing PEs, all the above multihoming procedures can be omitted; however, to allow for single-homing PEs to fully interoperate with multihoming PEs, some of the multihoming procedures described above SHOULD be supported even by single homing PEs:

  • procedures related to processing Ethernet A-D routes for the purpose of fast convergence (Section 8.2 ("Fast Convergence")), to let single-homing PEs benefit from fast convergence

  • procedures related to processing Ethernet A-D routes for the purpose of aliasing (Section 8.4 ("Aliasing and Backup Path")), to let single-homing PEs benefit from load balancing

  • procedures related to processing Ethernet A-D routes for the purpose of a backup path (Section 8.4 ("Aliasing and Backup Path")), to let single-homing PEs benefit from the corresponding convergence improvement
