Configuring IP Services
5-30 114065 Rev. A
Configuring Authentication on an Interface
OSPF provides a measure of security for an area through the use of passwords. If
an area is configured to use authentication, all OSPF interfaces configured in that
area must be configured with a password. The password must be identical on each
interface connected to the same network. Different networks can have different
passwords.
In such an area, a router that receives a packet verifies the password before doing
anything else with the packet. Unauthorized routers are not allowed to
communicate with the OSPF system.
By default, authentication is disabled on each interface. You can use Site Manager
to enable authentication on the interface.
If you have enabled authentication on the interface, you can use Site Manager to
specify a password.
Configuring an Area Border Router
Each area is connected to the backbone by one or more border routers. In
Figure 5-1, for example, R3 is a border router connecting Area 0.0.0.1 to the
backbone. A border router can have connections to multiple areas. In
Figure 5-6,
for example, Border router 2 has an interface to a network in Area B and an
interface to a network in Area C.
