Creates an aggregate entry in a BGP routing table.
The no version removes the aggregate.
Options
address—Aggregate IPv4 address
mask—Aggregate IPv4 mask
ipv6Prefix—Aggregate IPv6 prefix
as-set—If the as-set option
is not specified, the path attributes of the aggregate route are set
in the same way as locally originated routes, except that the atomic_aggregate
and aggregator attributes are added. If the as-set option is used, the path attributes of the
aggregate route are determined by combining the path attributes of
the aggregated routes as described in RFC 4271—A Border
Gateway Protocol 4 (BGP-4). If the as-set option is used, the path attributes of the aggregate route may change
whenever one of the aggregated routes changes, causing the aggregate
route to be readvertised.
summary-only—Filters all more specific routes from
updates. summary-only not only creates
the aggregate route but also suppresses advertisements of more-specific
routes to all neighbors. If you only want to suppress advertisements
to certain neighbors, you may use the neighbordistribute-list command, with caution.
If a more-specific route leaks out, all BGP speakers will prefer that
route over the less-specific aggregate you are generating (using longest-match
routing). Alternatively, you can use the suppress-map keyword to suppress specific routes.
attributeMapTag—String of
up to 32 characters that identifies the route map used to set the
attributes of the aggregate route
advertiseMapTag—String of
up to 32 characters that identifies the route map used to set the
routes to create AS-SET origin communities in the range
suppressMapName—String of
up to 32 characters that identifies a route map that filters routes
to be suppressed
*—Indicates that one or more parameters can be repeated
multiple times in a list in the command line
