5.4.3 Configuring BGP Route Aggregation
In a medium-/large-sized BGP network, you can reduce the number of the routes to be
advertised to BGP peers through route aggregation to save the spaces of BGP peer
routing tables. BGP supports two route aggregation modes: automatic aggregation
mode and manual aggregation mode.
Automatic aggregation mode, where IGP sub-network routes imported by BGP
are aggregated. In this mode, only the aggregated routes are advertised. The
imported IGP sub-network routes are not advertised. Note that the default routes
and the routes imported by using the network command cannot be automatically
aggregated.
Manual aggregation mode, where local BGP routes are aggregated. The priority of
manual aggregation is higher than that of automatic aggregation.
