DGS-3130 Series Layer 3 Stackable Managed Switch Web UI Reference Guide
226
Parameter Description
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.
Transmit Delay 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.
Retransmit Interval 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.
Click the Apply button to accept the changes made.

Parameter Description
Protocol
Select the source protocol from which routes will be redistributed here. Options
to choose from are Connected, Static, and RIPng.
Metric Type Select the external link type associated with the default route advertised into
the IPv6 OSPF routing domain here. Options to choose from are External
Type-1 and External Type-2. If a metric type is not specified, the Switch
adopts a Type-2 external route. This is only for IPv6 OSPF.
