vrf-target
Syntax vrf-target {ext-community | export ext-community | import ext-community}
no vrf-target
Context config>service>vprn
Description This command facilitates a simplified method to configure the route target to be added to advertised
routes or compared against received routes from other VRFs on the same or remote PE routers (via
MP-BGP).
BGP-VPN routes imported with a vrf-target statement will use the BGP preference value of 170 when
imported from remote PE routers, or retain the protocol preference value of the exported route when
imported from other VRFs in the same router.
Specified vrf-import or vrf-export policies override the vrf-target policy.
The no form of the command removes the vrf-target
Default no vrf-target
Parameters ext-comm — An extended BGP community in the type:x:y format. The value x can be an integer or IP
