Cisco ASA: OSPF routing

Design & Configure

Cisco ASA: OSPF routing

Technology: Firewall 

Area: Routing and Switching

Vendor: Cisco

Software: Cisco Adaptive Security Appliance (ASA)

Platform: Cisco ASA 5500, 5500-X



The Open Shortest Path First (OSPF) is an interior gateway routing protocol that uses link states for path selection and propagates link-state advertisements. OSPF uses a link-state algorithm to build and calculate the shortest path to all known destinations. Each router in an OSPF area contains an identical link-state database, which is a list of each of the router’s usable interfaces and reachable neighbors. 



To configure OSPFv2 use the command below: 

# internal interface configuration
interface GigabitEthernet1/4.10
vlan 10
nameif INSIDE
security-level 95
ip address 


#EIGRP configuration
asa(config)# router ospf 2
asa(config-rtr)# network area 0
