For OSPF to be fully functional, you must enter a valid ID address and subnet mask. For
more information, see
Configure the IP Interface on page 312.
Note: Once OSPF is initialized on the router, it remains initialized until the
router is reset.
8. In the Router Priority field, enter the OSPF priority for the selected interface.
The priority of an interface is specified as an integer from 0 to 255. The default is 1, which
is the highest router priority
. A value of 0 indicates that the router is not eligible to become
the designated router on this network.
9. Configure the Retransmit Interval by entering the OSPF retransmit interval for the specified
interface.
This is the number of seconds between link state advertisements for adjacencies
belonging to this router interface. This value is also used when retransmitting database
descriptions and link state request packets. The valid values range from 1 to 3600
seconds (1 hour). The default is 5 seconds.
10. Configure the Hello Interval by entering the OSPF hello interval for the specified interface in
seconds.
This parameter must be the same for all routers attached to a network. Values range from
1 to 65,535.
The default is 10 seconds.
11. Enter the OSPF Dead Interval for the specified interface in seconds.
This specifies how long a router waits to see a neighbor router’s hello packets before
declaring that the router is down.
This parameter must be the same for all routers
attached to a network. This value must be a multiple of the hello interval (for example, 4).
The valid values range from 1 to 65,535. The default is 40 seconds.
12. In the Iftransit Delay Interval field, enter the OSPF transit delay for the specified interface.
This specifies the estimated number of seconds it takes to transmit a link state update
packet over the selected interface.
The valid values range from 1 to 3600 seconds (1
hour). The default value is 1 second.
13. Configure MTU Ignore by selecting Enable or Disable from the list.
MTU Ignore disables OSPF MTU mismatch detection on received database description
packets.
The default value is Disable (MTU mismatch detection is enabled).
14. Configure Passive Mode by selecting Enable or Disable from the list.
