Routing

• uses same “longest-prefix match” routing as IPv4 CIDR

• straightforward changes to existing IPv4 routing protocols to handle bigger addresses

  • unicast: OSPF, RIP-II, IS-IS, BGP4+, …
  • multicast: MOSPF, PIM, …

• can use Routing header with anycast addresses to route packets through particular regions

  • e.g., for provider selection, policy, performance, etc.
