Configuring MBGP route summarization
To reduce the routing table size on medium-sized and large-sized MBGP networks, you must configure
route summarization on peers. MBGP supports the following summarization modes:
•
Automatic summarization—Summarizes subnets redistributed from IGP. With the feature
configured, MBGP advertises only summary natural networks rather than subnets. The default routes
and routes injected by the
network
command are not summarized.
•
Manual summarization—Summarizes MBGP local routes. A manual summary route has a higher
priority than an automatic one.
Follow these steps to configure MBGP route summarization:
