1 - Take the new class C and subnet it on the 224 netmask giving you 8
subnets with network addresses at 0, 32, 64, 96, 128, 160, 192 and 224.
Assign each PM-2E a subnet for the dynamic IP pool by setting the
assigned address to the network address plus one (1, 33, 65, etc.) and
then setting static routes in the routers surrounding the PMs (including
the PMs themselves.)
Nice thing about this is that static IP assignments are unaffected by the
change. Tough part is getting all the static routes setup.
2 - Move the PMs onto the new class C and partition out the dynamic pools
anyway you want (although using the 224 subnet scheme is a useful hedge
againist having to subnet again.)
Problem here is that any static IP accounts will need to be moved as well.
3 - use OSPF.
Don't know enough to have a clue how to start that process. :\
