Chapter 38 Configuring IP Unicast Routing
Configuring OSPF
OSPF typically requires coordination among many internal routers, area border routers (ABRs)
connected to multiple areas, and autonomous system boundary routers (ASBRs). The minimum
configuration would use all default parameter values, no authentication, and interfaces assigned to areas.
If you customize your environment, you must ensure coordinated configuration of all routers.
These sections contain this configuration information:
• Default OSPF Configuration, page 38-32
• Configuring Basic OSPF Parameters, page 38-35
• Configuring OSPF Interfaces, page 38-35
• Configuring OSPF Area Parameters, page 38-36
• Configuring Other OSPF Parameters, page 38-38
• Changing LSA Group Pacing, page 38-39
• Configuring a Loopback Interface, page 38-40
• Monitoring OSPF, page 38-40
Note To enable OSPF, the switch or stack master must be running the IP services feature set.
