aggregate-address (BGP)
To create a summary address in a Border Gateway Protocol (BGP) routing table, use the
aggregate-address command. To remove the summary address, use the no form of this command.
aggregate-address address/length [advertise-map map-name] [as-set] [attribute-map map-name]
[summary-only] [suppress-map map-name]
no aggregate-address address/length [advertise-map map-name] [as-set] [attribute-map
map-name] [summary-only] [suppress-map map-name]
Syntax Description
Command Default The atomic aggregate attribute is set automatically when an aggregate route is created with this
command unless the as-set keyword is specified.
Command Modes Address-family configuration mode
Command History
Usage Guidelines You can implement aggregate routing in BGP either by redistributing an aggregate route into BGP, or by
using the conditional aggregate routing feature.
Using the aggregate-address command with no keywords will create an aggregate entry in the BGP
routing table if any more-specific BGP routes are available that fall within the specified range. (A longer
prefix which matches the aggregate must exist in the RIB.) The aggregate route will be advertised as
coming from your autonomous system and will have the atomic aggregate attribute set to show that
information might be missing. (By default, the atomic aggregate attribute is set unless you specify the
as-set keyword.)
address/length Aggregate IPv4 address and mask length. Valid value for length is 1
to 32.
advertise-map map-name (Optional) Specifies the name of the route map used to select attribute
information from specific routes.
as-set (Optional) Generates the autonomous system set path information
and community information from the contributing paths.
attribute-map map-name (Optional) Specifies the name of the route map used to set the
attribute information for specific routes. The map-name is an
alphanumeric string up to 63 characters.
summary-only (Optional) Filters all more-specific routes from updates.
suppress-map map-name (Optional) Specifies the name of the route map used to conditionally
filter more specific routes. The map-name is an alphanumeric string
up to 63 characters.
