RIPng Configuration Overview

This section provides an overview of RIPng configuration.

Enabling RIPng on the device starts the RIPng process which then begins populating its routing table and sending and receiving routing updates. Use the ipv6 router rip command in configuration command mode to both enable RIPng on the device and enter RIPng configuration command mode.

Within RIPng configuration command mode:

Because IPv6 addressing prefix is ambiguous concerning network addressing compared to IPv4, you do not directly specify a network destination address. Instead, you enable RIPng on the interface using the ipv6 rip enable command and the interface address is automatically set as the network destination address.

An offset can be added or removed to the hop metric for all incoming or outgoing RIPng routes for a given interface. Adding an offset is used for the purpose of making an interface a backup. Use the ipv6 rip offset command in interface configuration mode to add or remove an offset for either incoming or outgoing RIPng routes.

RIPng Configuration Example

The following configuration example:

  • Enables the RIPng process on this device and enters RIPng configuration command mode
  • Configures VLANs 10 as a passive-interface
  • Changes the RIPng timers to a 25 second update time, a 150 second expiration interval, and a 100 second flush time:
  • Configures the redistribution of OSPF process ID 16546 routes over this RIPng process
  • Configures IPv6 access-list ipv6list1 with a rule to deny route 2001:0:0:0:21f:45ff:fe3d:21be/64 and applies the ACL to the distribution-list for outgoing packets on VLAN 20
  • Enables RIPng on VLANs 10 and 20
