OSPF and OSPFv3
390
M4300 Series and M4300-96X Fully Managed Switches User Manual
• LSA Ack interval
• Metric cost
For OSPFv3 to be fully functional, you must enter a valid IPv6 prefix/prefix length. This
can be done using the CLI IPv6 address command.
Note: Once OSPFv3 is initialized on the router, it remains initialized until the
router is reset.
9. Configure the Router Priority by entering the OSPFv3 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.
10. Configure the Retransmit Interval by entering the OSPFv3 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 0 to 3600
seconds (1 hour). The default is 5 seconds.
11. Configure the Hello Interval by entering the OSPFv3 hello interval for the specified interface
in seconds.
This parameter must be the same for all routers attached to a network. Value values
range from 1 to 65,535. The default is 10 seconds.
12. Enter the OSPFv3 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 is a multiple of the hello interval (for example, 4). The
valid values range from 1 to 65,535. The default is 40 seconds.
13. In the Iftransit Delay Interval field, enter the OSPFv3 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.
14. Configure MTU Ignore by selecting Enable or Disable from the list.
MTU Ignore disables OSPF MTU mismatch detection on receiving database description
packets. The default value is
Disable (MTU mismatch detection is enabled).
15. Configure Passive Mode by selecting Enable or Disable from the list.
Make an interface passive to prevent OSPF from forming an adjacency on an interface.
OSPF advertises networks attached to passive interfaces as stub networks. Interfaces
are not passive by default, meaning that the passive mode default is Disable.
