As the following configs,route-maps with MED for two gateway routers can do
the load balancing. And bgp always-compare-med should be applied on the both
gateways.
on gateway 1
router bgp 1
neigh a.a.a.a router-map b1ao out
bgp always-compare-med
route-map b1ao permit 10
match ip add 1
set metric 100
route-map b1ao permit 20
set metric 150
on gateway 2
router bgp 1
neigh b.b.b.b route-map b1bo out
bgp always-compare-med
route-map b1bo permit 10
match ip add 2
set metric 100
route-map b1bo permit 20
set metric 150
Thanks,
John Kim
