You have an established Layer 3 VPN between two PE devices. You are asked to only send certain routes from PE-1 over the VPN to the remote site while maintaining all the routes on the PE-1 device. You created a policy that matches the specific routes and then tags these routes with the appropriate target community values.
In this scenario, which configuration changes must be made to satisfy the requirement?
To achieve the requirement of sending only certain routes from PE-1 over the VPN while maintaining all routes on the PE-1 device, you need to use the vrf-export parameter in the configuration. The vrf-export parameter allows you to apply a policy that matches specific routes and tags them with the appropriate target community values under the routing-instance. This method filters the routes before they are sent to the remote PE device in the VPN, thereby ensuring only the desired routes are exported. Therefore, configuring the vrf-export parameter and applying the policy under the routing-instances vpn-a hierarchy is the correct approach.
