Configuring Aggregate Addresses
Using CIDR addressing, you can combine routes so that multiple routes are advertised
as a single route. CIDR replaces the concept of classes (such as Class A, Class B, and
Class C) with the concept of IP prefixes. An IP prefix is a network address that
indicates the number of bits that comprise the network number.
1. To combine multiple routes, use the aggregate command in Router BGP
Configuration mode, as shown below:
MOT(config-bgp)#aggregate <ip-address> <address-mask>
where:
ip-address is the aggregate IP address.
address-mask is the aggregate IP mask.
2. To identify the route map for selecting routes to be aggregated, use the aggregate
advertise-map command in Router BGP Configuration mode, as shown below:
MOT(config-bgp)#aggregate <ip-address> <address-mask> advertise-map
<name>
where:
ip-address is the aggregate IP address.
address-mask is the aggregate IP mask.
name is the route map name.
3. To generate autonomous system path information for the aggregate IP address
based on the routes selected for aggregaton, use the aggregate as-set command in
Router BGP Configuration mode, as shown below:
MOT(config-bgp)#aggregate <ip-address> <address-mask> as-set
where:
ip-address is the aggregate IP address.
address-mask is the aggregate IP mask.
