OSPF Menu (continued)

External Metric

Defines the metric that will be advertised by OSPF.

External Metric Type

For Type 1, the total metric of this route is composed of the internal metric (inside the

 

autonomous system) and the external metric (provided in the previous parameter). For

 

Type 2, the total metric of this route is the value provided in the previous parameter.

Parameters that apply only when OSPF on This Interface is Enable or Enable Inactive.

Area ID

Identifies the area to which the interface belongs. Areas are created here, then later

 

defined in CONFIG=>IP=>OSPF =>AREA. Has the format of an IP address, but is not

 

linked to any IP address in the system. Small OSPF networks will typically have only

 

one area (the backbone area represented by 0.0.0.0).

Router Priority

Priority used by OSPF in multicast networks to elect the designated router. A priority of

 

1 will make this router the most likely to be chosen. A priority of 2 will make it second

 

most likely. Set it to 0 (zero) if this router should never be the designated router.

Transit Delay in

Estimated transit time in seconds to route a packet through this interface. Use the

Seconds

preset value (1) or increase the number for slow links

Retransmit Interval *

Time in seconds between link-state advertisement retransmissions for adjacencies

 

belonging to this interface.

Hello Interval *

Time in seconds between the hello packets on this interface.

Dead Interval *

Inactivity time (seconds) before a neighbor router is considered down.

Poll Interval *

Time in seconds between the hello packets sent to an inactive, non-broadcast, multi-

 

access neighbor.

Password *

String of up to 8 characters used to authenticate OSPF packages. The use of this

 

password is enabled in CONFIG=>IP=>OSPF=>AREA=>AUTHENTICATION TYPE

Metric

Defines the cost for normal service. For consistent routing, this parameter should be

 

determined in the same manner for all routers in the OSPF Area. Normally, metric cost

 

is defined as an inverse function of interface throughput (e.g. 1 for 100Mbps, 10 for

 

10Mbps, 65 for T1, 1785 for 56kbps, etc).

Advertise Secondary

Causes the router to advertise additional addresses assigned to this interface. These

IP Address

are configured in CONFIG => INTERFACE =><LINK> =>NETWORK PROTOCOL =>IP.

* Inside a given area, these 4 parameters should be the same for all routers.
