Usage Guidelines
Route aggregation is the process of combining the characteristics of several routes so that they are
advertised as a single route. Aggregation reduces the amount of information that a BGP speaker must
store and exchange with other BGP speakers. Reducing the information that is stored and exchanged
also reduces the size of the routing table.
To use BGP route aggregation, follow these steps:
1
Enable aggregation using the following command:
enable bgp aggregation
2
Create an aggregate route using the following command:
configure bgp add aggregate-address {address-family [ipv4-unicast | ipv4-
multicast]} <ipaddress> {as-match | as-set} {summary-only} {advertise-policy
<policy>} {attribute-policy <policy>}
Example
The following command enables BGP route aggregation:
enable bgp aggregation
