Chapter 8: OSPF Flashcards
Initialize the OSPF Process
router ospf “process id”
Enable OSPF on network interfaces matching a specified network range for a specific OSPF area
network “ip address wildcard mask” area “area id”
Enable ospf on an explicit specific network interface for a specific OSPF area
ip ospf “process id” area “area id”
Configure a specific interface as passive
passive “interface id”
configure all interfaces as passive
passive interface default
Advertise a default route into OSPF
default-information originate [always] [metric “metric value”] [metric-type “type value”]
Modify the OSPF reference bandwidth for dynamic interface metric costing
auto-cost reference-bandwidth “bandwidth in mbps”
Statically set the OSPF metric for an interface
ip ospf cost “1-65535”
Configure the OSPF priority for a DR/BDR election
ip ospf priority “0-255”
Statically configure an interface as a broadcast OSPF network type
ip ospf network broadcast
Statically configure an interface as a point-to-point OSPF network type
ip ospf network point-to-point
Restart the ospf process
clear ip ospf process
Display the OSPF interfaces on a router
show ip ospf interface [brief | “interface id”]
Display the OSPF neighbors and their current states
show ip ospf neighbor [detail]
Display the OSPF routes that are installed in the RIB
show ip route ospf
