Right, sorry, the direction is reversed.
Well, all routing is normally done based on destination address.
Since in this case we want to use source address for routing, regardless of
destination, we need to use a special tool.
PBR fits this scenario very well I think.
Define the route-map on "GW router" matching all required source addresses
and setting the output interface to BB-router (or setting next-hop address
of BB-router).
For redundancy you can also set default network under the same match
statement, as per this document:
