This document describes a mechanism to model a broadcast network as a
hybrid of broadcast and point-to-multipoint networks for purposes of
OSPF operation. Neighbor discovery and maintenance as well as Link
State Advertisement (LSA) database synchronization are performed
using the broadcast model, but the network is represented using the
point-to-multipoint model in the router-LSAs of the routers connected
to it. This allows an accurate representation of the cost of
communication between different routers on the network, while
maintaining the network efficiency of broadcast operation. This
approach is relatively simple and requires minimal changes to OSPF.
This document updates both OSPFv2 (RFC 2328) and OSPFv3 (RFC 5340).
