25 RIPng Commands
This chapter describes commands used for the IPv6 interior gateway protocol RIPng.
To determine the best path to a distant network, a router using RIPng always selects the path that has
the least number of hops. Each router that data must traverse is considered to be one hop.
The routing table in a router using RIPng contains an entry for every known destination network. Each
routing table entry contains the following information:
IP address and prefix length of the destination network
●
Metric (hop count) to the destination network
●
IP address of the next hop router, if the destination is not directly connected
●
Interface for the next hop
●
Timer that tracks the amount of time since the entry was last updated
●
A flag that indicates if the entry is a new one since the last update
●
The source of the route, for example, static, RIPng, OSPFv3, etc.
●
The router exchanges an update message with each neighbor every 30 seconds (default value), or if
there is a change to the overall routed topology (also called triggered updates). If a router does not receive
an update message from its neighbor within the route timeout period (180 seconds by default), the
router assumes the connection between it and its neighbor is no longer available.
