Description
Hello Interval, the earlier topological changes will be detected, but more routing
traffic will ensue. This value must be the same for all routers and access servers
on a specific network. The range is from 1 to 65535 seconds. Select the Default
option to use the default value, which is 10 seconds.
Enter the Dead Interval value here, during which no packets are received and
after which a neighbor is regarded as offline. The interval is advertised in router
hello packets. This value must be the same for all routers and access servers on
a specific network. The range is from 1 to 65535 seconds. Select the Default
option to use the default value, which is 40 seconds.
Enter the priority value of the router here. The range is from 0 to 255. Set the
priority to help determine the OSPF Designated Router (DR) for a network. If two
routers attempt to become the DR, the router with the higher router priority
becomes the DR. If the router priority is the same for two routers, the router with
the higher router ID takes precedence.
Only routers with non-zero router priority values are eligible to become the
designated or backup designated router. Configure router priority for multi-access
networks (not point-to-point) only.
Select the Default option to use the default value, which is 1.
Enter the Transmit Delay value here. The range is from 1 to 65535 seconds. Link-
State Updates (LSUs) must have their ages incremented by the amount specified
in the seconds argument before transmission. The value assigned should take
into account the transmission and propagation delays for the interface.
If the delay is not added before transmission over a link, the time in which the LSA
propagates over the link is not considered. This setting has more significance on
very low speed links.
Select the Default option to use the default value, which is 1 second.
Enter the Retransmit Interval value here. The range is from 1 to 65535 seconds.
After sending an LSA to a neighbor, the router keeps the LSA until it receives an
acknowledgement. In case the router does not receive an acknowledgement
during the set time (the Retransmit Interval value), it retransmits the LSA. Set the
retransmission interval value conservatively to avoid unnecessary retransmission.
The interval should be greater than the expected round-trip delay between two
routers.
Select the Default option to use the default value, which is 5 seconds.
