redistribution into the MBGP
routing table.

Configuring MBGP route summarization

To reduce the routing table size on medium and large MBGP networks, you need to configure route
summarization on peers. MBGP supports automatic and manual 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 with the network command are not summarized.
Manual summarization—Summarizes MBGP local routes. A manual summary route has a higher
•
priority than an automatic one.
To configure MBGP route summarization:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address family
view.
4. Configure MBGP route
summarization.
