[FROG] import vrf <vrf_name> vs route-map match source-vrf <vrf_name>

[Donald Sharp]

the command `import vrf XXX` under the address family in bgp tells bgp
to take the routes in vrf X that are in that afi safi and to import
them into this bgp vrf afi safi.

the `match source-vrf XXX` command allows you to look at the
originating vrf for when you are making a route-map decision.
