Understanding IP Addressing B-183
Routers B and C (which could also be Netopia R910s) ser ve the two remote networks that are subnets of
a.b.c.0. The subnetting is accomplished by configuring the Netopia R910 with connection profiles for Routers B
and C (see the following table).
a.b.c.0. The subnetting is accomplished by configuring the Netopia R910 with connection profiles for Routers B
and C (see the following table).
The Netopia R910’s connection profiles for Routers B and C create entries in its IP routing table. One entr y
points to the subnet a.b.c.128, while a second entr y points to the subnet a.b.c.248. The IP routing table might
look similar to the following:
