Configure Community Lists
Configure community lists to specify permitted routes by using their BGP community. This list acts as a filter that matches communities or AS numbers.
Before you begin
-
You configure BGP on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router Configuration mode and the prefix ip bgp. The VRF must have an RP Trigger of BGP.
Note
Route refresh is not currently supported on non-default VRFs.
