Cooperative route filtering

The cooperative route filtering feature allows the user to move the filtering function of a
route-target import filter to a peer. In this situation, an Outbound Route Filter (ORF) is derived from
the contents of all of the route-target import commands of BGP configured VRFs on a PE and
shared with a peer PE. This ORF is then used to exclude any routes that are blocked by that ORF
from being sent by the peer PE to the PE with the route-target import commands that the ORF was
