Totally Stubby Area Configuration

Totally Stubby Area Configuration
Using the same network topology as we had for the stub area configuration, let’s examine how
to make Area 25 a totally stubby area. Remembering that the difference between a stub area and
a totally stubby area is that a totally stubby area doesn’t allow summary routes to be injected
into it; we need only change the configuration of RouterB. Because RouterB is the ABR, it will
be the router that will have the responsibility for blocking summary routes from entering the
totally stubby area. So, again consider our network, as illustrated in Figure 6.6.
