Router discovery
IPv6 nodes discover routers on the local link with router discovery. The IPv6 router discovery
process uses the following messages:
•

•
Router advertisement
Configured interfaces on an IPv6 router send out router-advertisement messages. Router-
advertisements are also sent in response to router-solicitation messages from IPv6 nodes on
the link.
Router solicitation
An IPv6 host without a configured unicast address sends router solicitation messages.
Multicast
Most of the IPv6 routing protocols use multicast addresses for sending some of the protocol
information, especially during the discovery phase. To receive these messages the device
registers the well-known multicast addresses when a particular protocol is enabled and
deregisters when the protocol is disabled.
As in IPv4, a multicast address is assigned to a set of interfaces belonging to different nodes. A
packet destined to a multicast address is routed to all interfaces identified by that address. The
IPv6 multicast address uses the FF00::/8 prefix which is equivalent to the Ethernet multicast
address of 33-33-.
Multicast neighbor solicitation exists for address resolution, duplicate address detection, and
multicast router solicitation and router advertisement
IPv6 and the Avaya Ethernet Routing Switch 8800/8600
IPv6 routing provides an underlying mechanism to transmit data blocks from source to
destination. The source and destination are hosts, identified by fixed-length IPv6 addresses.
The Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) provide a
transport facility for data transmission. TCP is a reliable mechanism. UDP is not as reliable as
TCP. Routing protocols identify the shortest path from a source to a destination. The Internet
