I don't see a way to clear it but you can delete the entries
with arp -d

2 gateways or 2 default gateways? If you need more than one
default gateway you likely will need to use iproute2 to set
that up.

If you have 1 default gateway and want to have another route(s)
pointing to another gateway add them to /etc/sysconfig/static-routes

e.g.

any net 192.168.0.0 netmask 255.255.0.0 gw 10.254.113.1


not sure why the syntax is not the same as the route command,
it's similar but not exactly the same.
