Cost Authentication LAN route exchange NSSA Enable Click Edit to open the Edit OSPFv2 page. It displays the cost of sending a packet on an OSPFv2 interface. It displays the authentication type. It displays the LAN Route Exchange status for a WAN interface. It displays whether NSSA is enabled or disabled. You can enable or disable the respective interface. Field Interface NSSA Area Priority Hello interval Dead interval Cost Authentication Type Authentication Key MD5 Key ID Description It displays the physical network interface on which OSPFv2 is enabled or disabled. Enable this option to allow OSPF stub areas to carry external routes. Enter the area to which the interface belongs. Two routers having a common segment; their interfaces have to belong to the same area on that segment. The interfaces should belong to the same subnet and should have a similar mask. It helps to determine the OSPFv2 designated gateway for a network. The gateway with the highest priority will be more eligible to become Designated Router. Setting the value to 0 makes the router ineligible to become Designated Router. The default value is 1. Lower the value means higher priority. Enter the number, in seconds, when the Hello packet is to be sent. This value must be the same for all gateways attached to a common network. The default value is 10 seconds. Enter the number of seconds when a device's hello packets are not seen before its neighbors declare the OSPF router down. This value must be the same for all routers attached to a common network. The default value is 40 seconds. OSPF requires these intervals to be the same between two neighbors. If any of these intervals are different, these routers will not become neighbors on a particular segment. Enter the cost of sending a packet on an OSPFv2 interface. Select one of the following authentication types: None: The interface does not authenticate OSPF packets. Simple: OSPF packets are authenticated using simple text keys. MD5: The interface authenticates OSPF packets with MD5 authentication. Enter the authentication key. This field is available when you select Simple as the Authentica tion Type. If you select MD5 as the Authentication Type, enter the MD5 key ID.

Field
Description
Interface
It displays the physical network interface on which OSPFv2 is enabled or disabled.
NSSA
Enable this option to allow OSPF stub areas to carry external routes.
Area
Enter the area to which the interface belongs. Two routers having a common segment; their
interfaces have to belong to the same area on that segment. The interfaces should belong to
the same subnet and should have a similar mask.
Priority
It helps to determine the OSPFv2 designated gateway for a network. The gateway with the
highest priority will be more eligible to become Designated Router. Setting the value to 0
makes the router ineligible to become Designated Router. The default value is 1. Lower the
value means higher priority.
Hello interval
Enter the number, in seconds, when the Hello packet is to be sent. This value must be the
same for all gateways attached to a common network. The default value is 10 seconds.
Dead interval
Enter the number of seconds when a device’s hello packets are not seen before its
neighbors declare the OSPF router down. This value must be the same for all routers
attached to a common network. The default value is 40 seconds. OSPF requires these
intervals to be the same between two neighbors. If any of these intervals are different, these
routers will not become neighbors on a particular segment.
Cost
