Configuring IRDP

ICMP Router Discovery Protocol (IRDP) is an alternative router discovery protocol using
ICMP messages on multicast links.
ICMP uses router discovery messages, known as router advertisements and router
solicitations. Each router periodically multicasts a router advertisement from each of its
multicast interfaces, announcing the IP address of that interface, and other router IP
addresses. Hosts discover the addresses of their neighbor routers by listening for the
