Geert.
You could also try BGP UNEQUAL COST LOAD BALANCIG (BGP MULTIPATH) or IBGP
MULTIPATH LOAD SHARING.
The first one works the same as EIGRP unequal cost load balancing where the
ebgp border routers propagate the bandwidth of their ebgp links to
the internal ibgp routers via extended community attribute, so the internal
routers can use this information to provide load balancing.
the second one designed for bgp mpls vpn architectures but also work in non
mpls networks.
