I should also note, the underlying OS needs to have:
- a writable filesystem (therefore, you cannot use the image method to run VyOS) - a copy of ampr-ripd for 32 or 64 bit, you're in luck, I have a copy that runs run on an x86_64 INTEL/AMD, as it was compiled on Ubuntu, as I recall, I only have 64-bit - you would also need to make firewall rules for a) input of IPENCAP and b) receipt of the RIP44 packets
I devised some methods in notes (because of the identified complexities in altering Vyatta at the time), but opted for a pure Ubuntu system. I'm very interested in helping you develop wiki instructions for VyOS!
