Syntax Description

This command has no arguments or variables.

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>}

The following command enables BGP route aggregation:
