The above output indicates that OSPF neighbor relationships have been successfully established with both R2 and R3. Let’s now verify that ASA1 has indeed established OSPF adjacency with R2 and R3 using show ospf neighbor command. INFO: Security level for “outside” set to 0 by default.ĪSA1(config-if)# ospf authentication message-digestĪSA1(config-if)# ospf message-digest-key 1 md5 ciscoĪSA1(config-if)# ip address 192.168.1.1 255.255.255.0 Towards the end of configuration given below, both outside and DMZ interfaces are assigned to the appropriate OSPF area using the network command.ĪSA1(config-if)# ip address 202.49.12.1 255.255.255.0 We will also configure MD5 authentication for OSPF on the outside and DMZ interfaces choosing cisco as the authentication key. We assigned a security level of 50 to the DMZ interface using the security-level command. Therefore, the most secured network is placed behind an interface with a security level of 100, whereas the least secured network is placed behind an interface with a security level of 0.Ī DMZ interface can be assigned a security level between 0 and 100. The higher the security level, the more secure an interface is. Inside and outside interfaces are assigned default security levels of 100 and 0 automatically. We will first configure interface IP addresses, at the same time assigning Ethernet0/0, Ethernet0/1, and Ethernet 0/2 to outside, inside, and DMZ (de-militarized zone) zones, respectively. Let’s now move to the interesting part where we will configure Cisco ASA.
