[FROG] Multiple routing tables and BGP

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 10.0.0.2 route-map custa_to_link in
  neighbor 10.0.0.6 route-map custb_to_link in
[..]

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

Thanks,
Philippe
