Aggregating routes advertised to BGP4 neighbors
By default, the device advertises individual routes for all networks. The aggregation feature allows you to congure the device to
aggregate routes from a range of networks into a single network
prex. For example, without aggregation, the device will individually
advertise routes for networks 10.95.1.0/24, 10.95.2.0/24, and 10.95.3.0/24. You can congure the device to end a single, aggregate
route for the networks instead. The aggregate route can be advertised as 10.95.0.0/16.
To aggregate routes for 10.157.22.0/24, 10.157.23.0/24, and 10.157.24.0/24, enter the following command.
device(config-bgp)# aggregate-address 10.157.0.0 255.255.0.0
Syntax: [no] aggregate-address ip-addr ip-mask [ as-set ] [ summary-only ] [ suppress-map map-name ] [ advertise-map map-
name ] [ attribute-map map-name ]
The ip-addr and ip-mask parameters specify the aggregate value for the networks. Specify 0 for the host portion and for the network
portion that diers among the networks in the aggregate. For example, to aggregate 10.0.1.0/24, 10.0.2.0/24, and 10.0.3.0/24, enter
the IP address 10.0.0.0 and the network mask 255.255.0.0.
The as-set parameter causes the device to aggregate AS-path information for all the routes in the aggregate address into a single AS-
path.
The summary-only parameter prevents the device from advertising more specic routes contained within the aggregate route.
The suppress-map map-name parameter prevents the more specic routes contained in the specied route map from being advertised.
The advertise-map map-name parameter congures the device to advertise the more specic routes in the specied route map.
The attribute-map map-name parameter congures the device to set attributes for the aggregate routes based on the specied route
map.
NOTE
For the suppress-map , advertise-map , and attribute-map parameters, the route map must already be
dened.
