Hi all,

In RFC2328,

"If the receiving interface connects to a broadcast

        network, Point-to-MultiPoint network or NBMA network the sender

        is identified by the IP source address found in the packet's IP

        header.  If the receiving interface connects to a point-to-point

        network or a virtual link, the sender is identified by the

        Router ID (source router) found in the packet's OSPF header."

Why do we do this? Is it ok to identify the neighbor by the router id
regardless of network types?
