On testing machines I use couple of loX + gifX to route traffic between
rdomains. It works great :)
- define 1 loopback address for each rdomain, all addresses in rdomain 0
- define gif tunnel from one loopback to another and affect the gif
interface to the right rdomain. Don't forget to define gif tunnels in
both directions!
Ex: gif1 in rdomain 1, lo1 -> lo2
gif2 in rdomain 2, lo2 -> lo1
..
