Configuring RIPv2 route summarization
Route summarization means that subnets in a natural network are summarized into a natural network that
is sent to other networks. This feature can reduce the size of routing tables.
After route summarization, the smallest metric among all the summarized routes is used as the metric of
the summary route.
