How would you establish the default gateway for b1, b2, ..., given that
a1, a2 and a3 can do NAT on behalf of the b's. I'd like to take advantage
of the fact that there are three possible default gateways for the b's to
give some redundancy if a1 (say) is shut down (no manual intervention).
three default gateways? routed? gated?
'gated' is probably the better solution, but unless a1..a3 are acting
like yo-yos (up/down/up/down) I'm not sure it's worth the extra hassle.
The kernel is going to ignore multiple gateways unless you are using
iproute2 and have set up policies.
