It adds a new vty command that permits exporting BGP entries to a
given routing table.

route-map custa_to_link permit 10
 set table 302
route-map custb_to_link permit 10
 set table 303
router bgp <>
 address-family ipv4 unicast
  neighbor route-map custa_to_link in
  neighbor route-map custb_to_link in

This should help you in solving the BGP exportation to the desired
table identifier, without using VRFs.
