OSPF functions and features, such as MD5 Authentication, Grace Period, Authentication Wait Time, etc.,
are assigned on a per interface basis.
Figure 20-9 shows an example of assigning an IP address to an interface and then assigning an OSPFv2
area that includes that Layer-3 interface’s IP address.
Figure 20-9. Configuring an OSPF Area Example
Dell Force10 recommends that the OSPFv2 Router ID be the interface IP addresses for easier management
and troubleshooting.
To view the configuration, use the
show config command in CONFIGURATION ROUTER OSPF mode.
OSPF, by default, sends hello packets out to all physical interfaces assigned an IP address that are a subset
of a network on which OSPF is enabled. To view the interfaces currently active and the areas assigned to
the interfaces, use the
show ip ospf interface command (Figure 20-10).
Figure 20-10. show ip ospf process-id interface Command Example
Note: If using features like MD5 Authentication, ensure all the neighboring routers are also configured for
MD5.
