Hello,
When trying to add export filters to a VRF/VPN Instance in Routing > BGP > VPN, all routes belonging to 'Copy' disappear from the routing table, leaving only Connected / Static, etc.
Is there a specific way in ROSv7 to achieve route filtering from within a VRF without making the Copied routes (from LDP) disappear?
Inversely, when trying to add import filters to a VRF/VPN Instance in Routing > BGP > VPN, no routes appear to have been filtered.
This is irrespective of whether local VRF route-leaking is used, or whether filtering from an external RT.
I have worked around this issue by creating a route filter specific to my route-reflector to filter out prefixes belonging to ext-bgp-communities (containing the route target), which does prevent the VPNv4 route from being distributed via BGP but I am looking for a more fine-grained approach on a per-VRF basis.

This 'issue' has been present since ROSv7 was released. I have been waiting for this functionality before doing serious testing with it on an MPLS network w/ L3VPN.
