The receiving RIPng router processes RTEs in the request. If only one RTE exists with the IPv6 prefix and

prefix length both being 0, and with a metric value of 16, the RIPng router will respond with the entire
routing table information in response messages. If multiple RTEs exist in the request message, the RIPng

router will examine each RTE, update its metric, and send the requested routing information to the

requesting router in the response packet.

Response packet

The response packet containing the local routing table information is generated as:

A response to a request

An update periodically

A trigged update caused by route change

After receiving a response, a router checks the validity of the response before adding the route to its
routing table, such as whether the source IPv6 address is the link-local address and whether the port

number is correct. The response packet that failed the check will be discarded.

Protocols and standards

RFC 2080, RIPng for IPv6

RFC 2081, RIPng Protocol Applicability Statement
