Configure Default Route Redistribution Into Mbgp; Configuring Mbgp Route Summarization - HP 4800G Series Configuration Manual

The Origin attribute of routes redistributed into the MBGP routing table with the import-route
command is Incomplete.
The Origin attribute of routes injected into the MBGP routing table with the network command is
IGP.
The networks to be injected must exist in the local IP routing table, and using a route policy makes
route control more flexible.

Configure Default Route Redistribution into MBGP

Using the import-route command cannot redistribute any default route into MBGP. This task allows you
to do so.
Follow these steps to configure MBGP to redistribute a default route from another protocol:
To do...
Enter system view
Enter BGP view
Enter MBGP address family
view
Enable route redistribution from
another routing protocol
Enable default route
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 two summarization modes: automatic and manual.
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.
Follow these steps to configure MBGP route summarization:
Enter system view
Enter BGP view
Enter IPv4 MBGP address family view

ipv4-family multicast
