Command introduced before JunosE Release 7.1.0.
Creates an aggregate entry in a BGP routing table. The no version removes the aggregate.
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 neighbor distribute-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
