434 CHAPTER 33: IPV6 RIPNG CONFIGURATION
Configuration
Prerequisites
Before the configuration, accomplish the following tasks first:
■ Enable IPv6 packet forwarding.
■ Configure an IP address for each interface, and make sure all nodes are
reachable.
Configuration Procedure Follow these steps to configure the basic RIPng functions:
n
If RIPng is not enabled on an interface, the interface will not send and receive any
RIPng route.
Configuring RIPng
Route Control
Before the configuration, accomplish the following tasks first:
■ Configure an IPv6 address on each interface, and make sure all nodes are
reachable.
■ Configure RIPng basic functions
■ Define an IPv6 ACL before using it for route filtering. Refer to “IPv6 ACL
Configuration” on page 851 for related information.
■ Define an IPv6 address prefix list before using it for route filtering. Refer to
section “Defining an IPv6 Prefix List” on page 491 for related information.
Configuring an
Additional Routing
Metric
An additional routing metric can be added to the metric of an inbound or
outbound RIP route, namely, the inbound and outbound additional metric.
The outbound additional metric is added to the metric of a sent route, the route’s
metric in the routing table is not changed.
The inbound additional metric is added to the metric of a received route before
the route is added into the routing table, so the route’s metric is changed.
Follow these steps to configure an inbound/outbound additional routing metric:
