Figure 33: OSPFv2 configure d parame te rs
Interface: The physical network interface on which OSPFv2 is Enabled/Disabled.
Status: This column displays the Enable/Disable state of OSPFv2 for a particular
interface.
Area: The area to which the interface belongs. Two routers having a common
segment; their interfaces have to belong to the same area on that segment. The
interfaces should belong to the same subnet and have similar mask.
Priority: Helps to determine the OSPFv2 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 devi
ce’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 b etween 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 OSPFv2 interface.
Authentication Type:. This column displays the type of authenticatio n to be used for
OSPFv2.If Authentication type is none the interface does not authenticate ospf
packets. If Authentication Type is Simple then ospf packets are authenticated using
simple text key. If Authentication Type is MD5 then the interface authentica tes ospf
packets with MD5 authentication.
