55 Router Discovery Protocol Commands Routers can be configured to periodically send router discovery messages to announce their presence to locally attached hosts. The router discovery message advertises one or more IP addresses on the router that hosts can use as their default gateway. Hosts can send a router solicitation message asking any router that receives the message to immediately send a router advertisement, so that the host does not have to wait for the next periodic message. Router discovery enables hosts to select from among multiple default gateways and switch to a different default gateway if an initially designated gateway goes down.
