OSPF virtual link configuration example
Network requirements
• In Figure 168, Area 2 has no direct connection to Area 0, and Area 1 acts as the Transit Area to
connect Area 2 to Area 0 via a virtual link between Firewall A and Firewall B.
• After configuration, Firewall A can learn routes to Area 2.
