I tested it on my deployment and it worked well when tested on
start-stop-status operations. I am using this script because I did not
have 3 IP addresses to allocate to a two node cluster. I used it in
combination with IPAddr2. It could be used to create a failover
capable routing device.

# Manages the default iproute. Could be used in a failover between
# network links. This script uses iproute -n. Avoid hostnames and
# the default keyword.
