• cost: Indicates the overhead required to send a packet across an interface. You can modify the cost
to differentiate between 100 Mbps and 1000 Mbps (1 Gbps) links. The command syntax is ipv6 ospf
cost number. The default cost is calculated by dividing 100 million by the bandwidth. For 10 Mbps
links, the cost is 10. The cost for both 100 Mbps and 1000 Mbps links is 1, because the speed of
1000 Mbps was not in use at the time the OSPF cost formula was devised.
• dead-interval: Indicates the number of seconds that a neighbor router waits for a hello packet from
the device before declaring the router down. The command syntax is ipv6 ospf dead-interval
seconds. The value can be from 1 through 2147483647 seconds. The default is 40 seconds.
• hello-interval: Represents the length of time between the transmission of hello packets. The
command syntax is ipv6 ospf hello-interval seconds. The value can be from 1 through 65535
seconds. The default is 10 seconds.
• instance: Indicates the number of OSPFv3 instances running on an interface. The command syntax
is ipv6 ospf instance number. The value can be from 0 through 255. The default is 1.
• MTU-ignore: Allows you to disable a check that verifies the same MTU is used on an interface
shared by neighbors. The command syntax is ipv6 ospf mtu-ignore. By default, the mismatch
detection is enabled.
• network: Allows you to configure the OSPF network type. The command syntax is ipv6 ospf
network [point-to-multipoint ]. The default setting of the parameter depends on the network type.
• passive: When you configure an OSPF interface to be passive, that interface does not send or
receive OSPF route updates. This option affects all IPv6 subnets configured on the interface. The
command syntax is ipv6 ospf passive. By default, all OSPF interfaces are active and thus can send
and receive OSPF route information. Since a passive interface does not send or receive route
information, the interface is in effect a stub network.
• active: When you configure an OSPFv3 interface to be active, that interface sends or receives all the
control packets and forms the adjacency. By default, the ipv6 ospf active command is disabled.
Whenever you configure the OSPFv3 interfaces to be passive using the default-passive-interface
command, all the OSPFv3 interfaces stop sending and receiving control packets. To send and
receive packets over specific interfaces, you can use the ipv6 ospf active command.
• priority: Allows you to modify the priority of an OSPF router. The priority is used when selecting the
designated router (DR) and backup designated routers (BDRs). The command syntax is ipv6 ospf
priority number. The value can be from 0 through 255. The default is 1. If you set the priority to 0,
the router does not participate in DR and BDR election.
• retransmit-interval: The time between retransmissions of LSAs to adjacent routers for an interface.
The command syntax is ipv6 ospf retransmit-interval seconds . The value can be from 0 through
3600 seconds. The default is 5 seconds.
• Transmit-delay: The time it takes to transmit Link State Update packets on this interface. The
command syntax is ipv6 ospf transmit-delayseconds. The range is 0 through 3600 seconds. The
default is 1 second.
Disabling or re-enabling event logging
OSPFv3 supports the logging of OSPFv3 events. The log-status change command controls the
generation of all OSPFv3 logs. You can disable or re-enable the logging of events related to OSPFv3,
such as neighbor state changes and database overflow conditions. By default, the Brocade device does
not logs these events.
To disable the logging of events, enter the following command.
device(config-ospf6-router)# no log-status-change
Syntax: [no] log-status-change
To re-enable the logging of events, enter the following command.
device(config-ospf6-router)# log-status-change
Disabling or re-enabling event logging
