M4300 Intelligent Edge Series Fully Managed Stackable Switches OSPF uses this value in computing shortest paths. The range is from 1 to 65,535. The default is 1. Metric Cost is configurable only if OSPFv3 is initialized on the interface. 17. Click the Apply button. Your settings are saved. The following table describes the nonconfigurable information that is displayed. Table 145. Advanced OSPFv3 Interface Configuration Field IPv6 Address LSA Ack Interval (secs) State Description The IPv6 address of the interface. The number of seconds between LSA acknowledgment packet transmissions, which must be less than the retransmit interval. The current state of the selected router interface. State is one of the following: • Down. This is the initial interface state. The lower-level protocols indicate that the interface is unusable. Interface parameters are set to their initial values. All interface timers are disabled, and there are no adjacencies associated with the interface. • Loopback. The router's interface to the network is looped back in either the hardware or software. The interface is unavailable for regular data traffic. However, you might want to gain information about the quality of this interface, either through sending ICMP pings to the interface or through something like a bit error test. For this reason, IP packets can still be addressed to an interface in the loopback state. To facilitate this, such interfaces are advertised in router LSAs as single host routes, whose destination is the IP interface address. • Waiting. The router is trying to determine the identity of the backup designated router for the network by monitoring received hello packets. The router is not allowed to elect a backup designated router or a designated router until it transitions out of waiting state. This prevents unnecessary changes of backup designated router. • Designated Router. This router is the designated router on the attached network. Adjacencies are established to all other routers attached to the network. The router must also originate a network-LSA for the network node. The network-LSA contains links to all routers (including the designated router) attached to the network. • Backup Designated Router. This router is the backup designated router on the attached network. It is promoted to designated router if the present designated router fails. The router establishes adjacencies to all other routers attached to the network. The backup designated router performs slightly different functions during the LSA flooding procedure, as compared to the designated router. • Other Designated Router. The interface is connected to a broadcast or NBMA network on which other routers were selected to be either the designated router or backup designated router. The router attempts to form adjacencies to both the designated router and the backup designated router. Note: The state is displayed only if the OSPFv3 Admin mode is enabled.
