22. RIPng Commands 22 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. clear ripng counters clear ripng counters {vlan | tunnel } Description Clears the RIPng global or interface-specific counters (statistics). Syntax Description vlan-name tunnel-name Specifies an IPv6 configured VLAN. Specifies an IPv6 tunnel. Chapter 22. RIPng Commands | 973
