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).
    ipv6 ospf priority 
                                        number
