route-target
Overview
Use this command within a specific VRF instance, to create a route-target within
the BGP extended communities path attribute field. This value can then be
included in a list of import and export route target extended communities for the
specified VRF instance. Learned routes that carry a specific route-target extended
community are then imported into all VRFs configured with that extended
community as an imported route-target.
The
no
variant of this command removes a route-target extended community for
the VRF instance specified.
Syntax
route-target {import|export|both} {
ASN:n|ip-address:n
}
no route-target {import|export|both} {
ASN:n|ip-address:n
}
Mode
VRF Configuration
Default
No route-target community attributes are associated with a VRF instance.
Usage
In VRF systems that use MPLS, there is an close relationship between the Route
Target (RT) and the Route Distinguisher (RD) values. For VRF-lite however, this
relationship is only implicit in that they share the same format structure.
Example
Use the following commands to create a route-target extended community for
ASN value 200, and a Reference number of 3, within the VRF instance blue:
awplus#
config terminal
awplus(config)#
ip vrf blue
awplus(config-vrf)#
route-target import 200:1
Parameter
Description
route-target
Specifies a BGP extended community as a route-target.
import
Adds the route target to its import list.
export
Adds the route target to its export list.
both
Adds the route target to both the import and export lists.
<
ASN:n
>
The route target reference number. This uses the same structure
that is defined for the RD. This being, ASN number:Ref number.
The ASN value can be any number between 1 and 65535, and the
value n can be any number between 1 and 4294967295.
<
ip-address:n
>
The route target reference number. This uses the same structure
that is defined for the RD (Route Distinguisher). This being
IP-address:Ref number.
In practice, the IP-address can be an entry in IPv4 format, or an
integer number between 1 and 4294967295. The value n can be
any number between 1 and 65535.
