area { ipaddress | decimal_value } authentication [ message-digest ] no area { ipaddress | decimal_value } authentication [ message-digest ]The following command enables authentication for an OSPF area defined by the IP address 192.168.100.10 and the OSPF authentication type to MD5:area 192.168.100.10 authentication message-digestarea { ipaddress | decimal_value } default-cost cost_value no area { ipaddress | decimal_value } default-cost cost_valueThe following command sets the default cost for an OSPF area defined by the IP address 192.168.100.10 to 300:area { ipaddress | decimal_value } nssa [default-information-originate] [no-redistribution no-summary] [translate-always] [translate-candidate] [translate-never]The following command defines the area designated by the IP address 192.168.100.10 as an NSSA area:area 192.168.100.10 nssaThe following command defines the OSPF area defined by the IP address 192.168.100.10 as a stub area:area 192.168.100.10 stubThe following command creates a virtual link between the OSPF areas defined by the IP address 192.168.100.10 and the IP address 192.168.200.20:The following command sets the authentication method for a virtual link between the OSPF areas defined by the IP address 192.168.100.10 and the IP address 192.168.200.20 to use no authentication:area { ipaddress | decimal_value } virtual-link router_id_address authentication-key [ encrypted ] password authentication_keypassword authentication_keyThe password to use for authentication. authentication_key is a string variable, from 1 through 16 alphanumeric characters, that denotes the authentication password. This variable is entered in clear text format.The following command creates an authentication password of 123456 for a virtual link between the OSPF areas defined by the IP address 192.168.100.10 and the IP address 192.168.200.20:area { ipaddress | decimal_value } virtual-link router_id_address [ dead-interval value ] [ hello-interval value ] [ retransmit-intervalvalue ] [ transmit-delay value ]dead-interval valueThe interval, in seconds, that the router should wait, during which time no packets are received and after the router considers a neighboring router to be off-line. value must be an integer from 1 through 65535.hello-interval valueThe interval, in seconds before sending a hello packet. value must be an integer from 1 through 65535.retransmit-interval valueThe interval, in seconds, that router should wait before retransmitting a packet. value must be an integer from 1 through 65535.transmit-delay valueThe interval, in seconds, that the router should wait before transmitting a packet. value must be an integer from 1 through 65535.The following command sets the retransmit interval for a virtual link between the OSPF areas defined by the IP address 192.168.100.10 and the IP address 192.168.200.20 to 60 seconds:area { ipaddress | decimal_value } virtual-link router_id_address message-digest-key key_id md5 [ encrypted ] password authentication_keypassword authentication_keyThe password to use for authentication. authentication_key is a string variable, from 1 through 16 alphanumeric characters, that denotes the authentication password. This variable is entered in clear text format.The following command enables the use of MD5-based OSPF authentication for a virtual link between the OSPF areas defined by the IP address 192.168.100.10 and the IP address 192.168.200.20, sets the MD5 Key ID to 25, and the password to 123456:default-information originate [ always ] [ metric metric_value ] [ metric-type { 1 | 2 } ] [ route-map route_map_name ]metric metric_valueroute-map route_map_namedefault-metric metric_valuedefault-metric 235distance { distance_value | ospf { [ external distance_value ] [ inter-area distance_value ] [ intra-area distance_value ] } }external distance_value: Set the OSPF route administrative distance for routes from other routing domains, learned by redistribution. This must be an integer from 1 through 255. The default is 110.inter-area distance_value: sets the OSPF route administrative distance for routes from one routing area to another. This must be an integer from 1 through 255. The default is 110.intra-area distance_value: sets the OSPF route administrative distance for all routes within an area. This must be an integer from 1 through 255.
