is causing network problems due to heavy ARP loads when the local

is an issue when there are large blocks of IP addresses behind a
router. It is less of a problem when there is a relatively small
number of IP addresses behind a router (say one class C worth). Are
others seeing these sorts of problems?  What strategies are there for
dealing with this?

Use smaller subnets (possibly vlans etc) !
