BGP Commands

ip bgp aggregate-address

Creates and deletes a BGP aggregate route. Aggregate routes are used to reduce the size of routing tables
by combining the attributes of several different routes and allowing a single aggregate route to be adver-
tised to peers.
The base command (ip bgp aggregate-address) may be used with other keywords to set up aggregate
address configuration. These keywords are listed here and described as separate commands later in this
chapter. In addition, some keywords have a no form to remove the parameter or return it to its default.
Note that only one of the following optional keywords is specified with each use of the base command.
Keywords are not combined together in a single command.
