Release Information

Statement introduced before Junos OS Release 7.4.

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Description

Associate BGP community information with a static, aggregate, or generated route.

Options

community-ids—One or more community identifiers. The community-ids format varies according to the type of attribute that you use.

The BGP community attribute format is as-number:community-value:

as-number—AS number of the community member. It can be a value from 1 through 65,535.
community-value—Identifier of the community member. It can be a number from 0 through 65,535.

For more information about BGP community attributes, see the “Configuring the Extended Communities Attribute” section in the Junos Policy Framework Configuration Guide.

For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997:

no-advertise—Routes containing this community name are not advertised to other BGP peers.
no-export—Routes containing this community name are not advertised outside a BGP confederation boundary.
no-export-subconfed—Routes containing this community name are not advertised to external BGP peers, including peers in other members’ ASs inside a BGP confederation.
none—Explicitly exclude BGP community information with a static route. Include this option when configuring an individual route in the route portion to override a community option specified in the defaults portion.

Note: Extended community attributes are not supported at the [edit routing-options] hierarchy level. You must configure extended communities at the [edit policy-options] hierarchy level. For information about configuring extended communities, see the Junos Policy Framework Configuration Guide.
