Although the passive interface does not send or receive routing updates, the network on that interface is still included in
OSPF updates sent through other interfaces. You can remove an interface from passive interfaces using the no ipv6 ospf
passive command.
1. Enter an interface type in INTERFACE mode.
interface ethernet node/slot/port[:subport]
2. Configure the interface as a passive interface in INTERFACE mode.
ipv6 ospf passive

Interface OSPFv3 Parameters
Interface parameter values must be consistent across all interfaces to avoid routing errors. For example, set the same time
interval for the hello packets on all routers in the OSPF network to prevent misconfiguration of OSPF neighbors.
1. Enter the interface to change the OSPFv3 parameters in CONFIGURATION mode.
interface interface-name
2. Change the cost associated with OSPFv3 traffic on the interface in INTERFACE mode (1 to 65535, default depends on the
interface speed).
ipv6 ospf cost
3. Change the time interval the router waits before declaring a neighbor dead in INTERFACE mode (1 to 65535, default 40).
The dead interval must be four times the hello interval. The dead interval must be the same on all routers in the OSPFv3
network.
ipv6 ospf dead-interval seconds
4. Change the time interval (in seconds) between hello-packet transmission in INTERFACE mode (1 to 65535, default 10). The
hello interval must be the same on all routers in the OSPFv3 network.
ipv6 ospf hello-interval seconds
5. Change the priority of the interface, which determines the DR for the OSPFv3 broadcast network in INTERFACE mode (0 to
255, default 1).
