cost_value is the default cost to be configured for the specified area and must be an integer from 0 through 16777215.
default-information-originate: This optional keyword configures the OSPF VRF instances to originate default information to the NSSA area.
no-redistribution: This optional keyword configures the OSPF VRF instance to not to redistribute external routes to the NSSA area.
no-summary: This optional keyword configures the OSPF VRF instance to not to inject the inter-area routes into NSSA.
translate-always: This optional keyword configures the NSSA-ABR always to translate. By default this is disabled.
translate-candidate: This optional keyword configures the NSSA-ABR always to translate election. By default this is enabled.
translate-never: This optional keyword configures the NSSA-ABR never to translate. By default this is disabled.
router_id must be an IP address in IPv4 dotted-decimal notation of the ABR to be linked to.
key_id must be an integer from 1 through 255.
Specifies the password required for virtual link connection authentications. The keyword password is optional and if specified
passwd_string must be from 1 to 63 alpha and/or numeric characters. The password specified must be in an encrypted format if the optional keyword
encrypted was specified.
The encrypted keyword is intended only for use by the system while saving configuration scripts. The system displays the
encrypted keyword in the configuration file as a flag that the variable following the
password keyword is the encrypted version of the plain text password. Only the encrypted password is saved as part of the configuration file.
The following command defines the area designated by the IP address 192.168.100.10 as an NSSA area where translation of NSSA candidate is enabled by default:
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:
1: Sets the OSPF external link type for default routes to Type 1.
2: Sets the OSPF external link type for default routes to Type 2.
value must be an integer from 1 through 16777214.
1: Sets the OSPF external link type for routes to Type 1.
2: Sets the OSPF external link type for routes to Type 2.
Filter routes through the specified route map before redistribution. route_map_name specifies the name of the route-map to use and must be specified as a string of 1 through 79 alphanumeric characters.
