aggregate-address
Syntax
[ no ] aggregate-address { address mask | ipv6Prefix }
[ as-set | summary-only | attribute-map attributeMapTag |
advertise-map advertiseMapTag | suppress-map suppressMapName ]*
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
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
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
