iproute2 source routing to remote host

Hi,
I would like to setup source routing to a remote host, preventing the
packets to be routed via satellite. I know a better route to this host
than the default route which is used by the provider.

I figure there must be a solution to this by using the nexthop directives
provided by 'ip route'. Can someone please help me out on this and tell me
what I should try, or where I can find some iproute2 information that goes
beyond setting up source routing for lcr/fallback routes on local nets?

Thanks!
Sven
