BigIron RX Series Configuration Guide 110153-1001986-01Chapter44Configuring RIPngRouting Information Protocol (RIP) is an IP route exchange protocol that uses a distance vector (anumber representing a distance) to measure the cost of a given route. RIP uses a hop count as itscost or metric.IPv6 RIP, known as Routing Information Protocol Next Generation or RIPng, functions similarly toIPv4 RIP version 2. RIPng supports IPv6 addresses and prefixes.In addition, Brocade implements some new commands that are specific to RIPng. This chapterdescribes the commands that are specific to RIPng. This section does not describe commands thatapply to both IPv4 RIP and RIPng. For more information about these commands, refer to“Configuring RIPng” on page 1101RIPng maintains a Routing Information Database (RIB), which is a local route table. The local RIBcontains the lowest-cost IPv6 routes learned from other RIP routers. In turn, RIPng attempts to addroutes from its local RIB into the main IPv6 route table.This chapter describes the following:• How to configure RIPng• How to clear RIPng information from the RIPng route table• How to display RIPng information and statisticsConfiguring RIPngTo configure RIPng, you must do the following:• Enable RIPng globally on the Brocade device and on individual router interfacesThe following configuration tasks are optional:• Change the default settings of RIPng timers• Configure how the Brocade device learns and advertises routes• Configure which routes are redistributed into RIPng from other sources• Configure how the Brocade device distributes routes through RIPng• Configure poison reverse parametersEnabling RIPngBefore configuring the Brocade device to run RIPng, you must do the following:• Enable the forwarding of IPv6 traffic on the Brocade device using the ipv6 unicast-routingcommand.• Enable IPv6 on each interface over which you plan to enable RIPng. You enable IPv6 on aninterface by configuring an IPv6 address or explicitly enabling IPv6 on that interface.
