Router Discovery
The Router Discovery protocol is used by hosts to identify operational routers on the subnet. Router Discovery
messages are of two types: “Router Advertisements” and “Router Solicitations.” The protocol mandates that
every router periodically advertise the IP Addresses it is associated with. Hosts listen for these advertisements
and discover the IP Addresses of neighboring routers.
