z 

The Origin attribute of routes redistributed into the MBGP routing table with the import-route 

command is Incomplete.  

z 

The Origin attribute of routes injected into the MBGP routing table with the network command is 

IGP. 

z 

The networks to be injected must exist in the local IP routing table, and using a route policy makes 

route control more flexible. 

 

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: 

Enter system view 

— 

Enter BGP view  

bgp as-number 

— 

Enter MBGP address family 
view  

— 

Enable route redistribution from 
another routing protocol 

import-route protocol 
[ process-id [ med med-value | 
route-policy 
route-policy-name ] * ] 

Required 

No route redistribution is 
configured by default. 

Enable default route 
redistribution into the MBGP 
routing table 

Required 

Not enabled by default 

 

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. 

z 

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. 

z 

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 

bgp as-number 

— 

Enter IPv4 MBGP address family view
