Figure 35: OSPFv3 configured parameters
Interface: The physical network interface on which OSPFv3 is Enabled/Disabled.
Status: This column displays the Enable/Disable state of OSPFv3 for a particular
interface.
Priority: Helps to determine the OSPFv3 designated router for a network. The router
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 Value means higher priority.
HelloInterval: The number of seconds for HelloInterval timer value. Setting this
value, Hello packet will be sent every timer value seconds on the specified interface.
This value must be the same for all routers attached to a common network. The
default value is 10 seconds.
DeadInterval: The number of seconds that a device’s hello packets must not have been
seen before its neighbours 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 exactly the same between two neighbours. If any
of these intervals are different, these routers will not become neighbours on a
particular segment
Cost: The cost of sending a packet on an OSPFv3 interface.
