Link failover with ping
I`m finding docs/examples about this subject. After some googling,
I only found basic scripts. For me (in some networks that I work),
these simple scripts available only works with excellent links
The load balancing part of the problem already was solved with
LARTC howto. DGD patch for linux was not a good experience
because it only detects the first hop fail and 90% of these fails
happens after the first hop (e.g. local router as gateway
connected to remote ISP).
I searched for some linux distro with this feature (good failover)
bult-in, but didnt found something interesting.
I would appreciate pointers to docs, distros (for use as starting
point), examples or even academic research about the topic.
