Re: more than one default gw route

[John Mahoney <jmahoney waav com>]

I like the idea of the "MAC-detection or ping functionality", might I recommend using httping it tends to appear more friendly to the general public and is less likely to be dropped than a ping by networks.

The method of having multiply default routes with different weights is not the same as having two *active* default routes.  If two defaults routes were active and load balancing was to be performed  it would have to be balanced per (src ip,dest ip) tuple flows so that related connections were not confused.

I would love to see fail-over, as I'm sure many others would.

Oh, it won't break things down at all.  But the first default route in
the routing table will be the one that gets used for new outgoing
connections.  So it's pretty pointless to have more than one at a time.
Only one can truly the be the "default" route, and if you have more than
one, the lower-priority ones are more or less ignored by the kernel
entirely.
