Routers B and C (which could also be Netopia R6000 Series Routers) serve the two remote networks that are
subnets of a.b.c.0. The subnetting is accomplished by configuring the Netopia R6000 Series with connection
profiles for Routers B and C (see the following table).
The Netopia R6000 Series’s connection profiles for Routers B and C create entries in its IP routing table. One
entry points to the subnet a.b.c.128, while a second entry points to the subnet a.b.c.248. The IP routing table
might look similar to the following:
Connection profile Remote IP address Remote IP mask
Bits available for host
address
For Router B a.b.c.128 255.255.255.192 7
For Router C a.b.c.248 255.255.255.248 3
