VLSM = Variable Length Subnet masks. You don't have to split the subnets
evenly. 1/4 of the IPs on one subnet, 3/4 on the other.... etc...
CIDR = Classless Inter-Domain Routing. CLass A/B/C is meaningless, lets you
glue to C-classes together, lop of a chunk easily, etc...
OSPF = Open Shortest Path First. A newer routing protocol, slowly replacing
RIP. It is almost completely different, designed for modern topologies and
more efficient routing. But it's tables get to be HUGE.
BGP(4) = Border Gateway Protocol(4). Used by border routers mostly.
Now, did I munge any of those?
