Configuring Ripv2 Route Summarization - HPE FlexNetwork HSR6800 Configuration Manual

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 becomes 16.
To configure additional routing metrics:
Step
Enter system view.
1.
Enter interface view.
2.
Specify an inbound

additional routing metric.
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
Enter system view.
1.
Enter RIP view.

route summarization.
Advertising a summary route
Perform this task to manually configure a summary route.
For example, suppose contiguous subnets routes 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24 exist in
the routing table. You can create a summary route 10.1.0.0/16 on GigabitEthernet 1/0/1 to advertise
the summary route instead of the more specific routes.
To configure a summary route:
Command

interface interface-type

rip metricin [ route-policy
route-policy-name ] value
rip metricout [ route-policy
route-policy-name ] value
Command

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