Configuring An Additional Routing Metric; Configuring Ripv2 Route Summarization - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

Configuring an additional routing metric

An additional routing metric (hop count) can be added to the metric of an inbound or outbound RIP
route.
An outbound additional metric is added to the metric of a sent route, and it does not change the route's
metric in the routing table.
An inbound additional metric is added to the metric of a received route before the route is added into the
routing table, and the route's metric is changed. If the sum of the additional metric and the original metric
is greater than 16, the metric of the route is 16.
To configure additional routing metrics:
Step
1. Enter system view.
2. Enter interface view.
3. Specify an inbound
additional routing metric.
4. Specify an outbound
additional routing metric.

Configuring RIPv2 route summarization

Perform this task to summarize contiguous subnets into a summary network and sends the network to
neighbors. The smallest metric among all summarized routes is used as the metric of the summary route.
Enabling RIPv2 automatic route summarization
Automatic summarization enables RIPv2 to generate a natural network for contiguous subnets. For
example, suppose there are three subnet routes 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24. Automatic
summarization automatically creates and advertises a summary route 10.0.0.0/8 instead of the more
specific routes.
To enable RIPv2 automatic route summarization:
Step
1. Enter system view.
2. Enter RIP view.
3. (Optional.) Enable RIPv2
automatic route
summarization.
Advertising a summary route

By default, RIPv2 automatic route
summarization is enabled.
If subnets in the routing table are
not contiguous, disable automatic
route summarization to advertise
more specific routes.
