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. Command system-view bgp as-number ipv4-family multicast Remarks N/A N/A N/A 4. Configure MBGP route summarization. Enable automatic route summarization: summary automatic Configure manual route summarization: aggregate ip-address { mask | mask-length } [ as-set | attribute-policy route-policy-name | detail-suppressed | origin-policy route-policy-name | suppress-policy route-policy-name ] * Use either command No route summarization is configured by default. If the two commands are both configured, the manual route summarization takes effect. Advertising a default route to an IPv4 MBGP peer or peer group Step 1. Enter system view. Command system-view 2. Enter BGP view. 3. Enter IPv4 MBGP address family view. bgp as-number ipv4-family multicast 4. Advertise a default route to an peer { group-name | ip-address } MBGP peer or peer group. default-route-advertise [ route-policy route-policy-name ] Remarks N/A N/A N/A Not advertised by default. 189
