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.

Usage Guidelines
• Use the no form of this command to delete an aggregate route.
• This command allows administrative operations on a BGP aggregate. You must still enable the aggre-
gate route through the
command.
• You cannot aggregate an address (for example, 100.10.0.0) if you do not have at least one more-
specific route of the address (for example, 100.10.20.0) in the BGP routing table.
