What happens if only one of many routes in a multpiath rote fails?
Suppose that there are three gateways thru 3 different ISPs connected to a single host.
eth0 GW: 126.96.36.199
eth1 GW: 188.8.131.52
eth2 GW: 184.108.40.206.
I would do this:
ip route add default netxhop via 220.127.116.11 dev eth0 nexthop via 18.104.22.168 dev eth1 nexthop via 22.214.171.124 dev eth2
Perfect... now I have a single default route joining all three connections. But what happens in case one of the three connections fails? Will iproute2 "deactivate" it from the multipath route automaginally until it comes back online again?
