IPv6 RIP-NG

  • RIP still runs on UDP/521
  • Still considered distance vector protocol.
  • Still has a maximum hop-count of 15.
  • 16 hops is considered unreachable.
  • Split Horizon is turned on by default.
  • Still as Administrative Distance of 120.
  • Uses Multicast Address FF02::9 for all its communication.
  • No network command to enable anymore – done on the interface.
  • Uses link local addresses for its multicast communication.

IPv6 routing needs to be enabled: ipv6 unicast-routing

Enable RIP: ipv6 rip <tag> enable  under the chosen interface.

Example:

R1(config)#interface e0/0
R1(config-if)#ipv6 rip CBTNUGGETS enable

The tag defined is locally significant only

Verification
