There are two kinds of multipath routing in the kernel (which are differently
implemented in the kernel and do different things):
- default route failover. You configured it. It doesn't do any load balancing,
but when your default route stops working it'll eventually try the other
one. You configured that.
- real multipath routing.
It is configured by setting multiple nexthops to a single route
(ip route add ... nexthop ... )
The kernel will do load balancing by route (=srcip/dstip/tos tripple)
