So big picture at this point .. We have: requirement to distribute multi-AF routes (IPv4 or IPv6) between AF access islands connected to a single AF backbone network requirement to use that reachability information to forward AF packets (IPv4 or IPv6) across that backbone network from one access island network to another requirement to encapsulate AF island-sourced IPv4 or IPv6 packets for transport across AF backbone network This has similarities to the classic L3VPN problem and solution space. Let’s take a look … |
