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
