OSPF Parameters

For more details regarding the exact meaning of all OSPF parameters, consult related
Request For Comments (RFCs) documents: RFC 1131, RFC 1247, RFC 1583, etc.

Enable OSPF for This Circuit

This option activates and de-activates the OSPF support of this circuit as desired. If
OSPF for this Circuit is enabled, the Area ID of This Circuit must be configured.
The default value is Yes.

Area ID of This Circuit

This is a 32-bit number that identifies the router’s area. The Area ID of 0 is
reserved for the backbone.

Seconds between LSA

This parameter is the number of seconds between link state advertisement
retransmissions, for adjencies belonging to this interface. It ranges from 1 to 3600.
It is also use when retransmitting Database Description and Link State Request
Packets. The default value is 5.

Transmit Delay for LSU Packets

This parameters is the estimated number of seconds it takes to transmit a Link
State Update Packet over this circuit interface. It ranges from 1 to 3600. This value
should take into account the transmission and propagation delays of the circuit. It
must be greater than zero. The default value is 1.

Router Priority

This parameter is an 8-bit unsigned integer. It ranges from 1 to 255. When two
routers are attached to the same network, both routers attempt to become the
designated router. Higher priority wins. In case of a tie, the router with the higher
Router ID wins. A router having a priority set to 0 cannot become a designated
router. The default value is 1.

Hello Interval

This is the time, in seconds, between the Hello packets that a router sends on a
circuit. This value is also advertised in the router’s Hello packets. It ranges from 1
to 65535. It must be identical for all routers on the same network. Remember that
the smaller the Hello Interval, the sooner topological changes are detected, but
more traffic is then created. The default value is 10.

Dead Interval

This parameter is the number of seconds that a router’s Hellos have not been
received before its neighbors declare the router down. It ranges from 1 to 65535.
This is also advertised in the router’s Hello packets in the DeadInt field. This
should be a multiple of the Hello Interval. This value, also, must be the same on
the network. The default value is 40.

Authentication Key

When configured, this parameter allows an authentication procedure to be executed
on the OSPF header. If the 64-bit (eight-character) password does not correspond,
the packet is thrown away. The default value is eight spaces for no authentication.
