UMN:CLI User ManualV810268212.3.3.1 Interface CostOSPFv3 protocol assigns suitable cost according to the bandwidth on the each interfaceto find the shortest route. The cost is used for packet routing, and routers are using theCost to communicate.To set an interface cost for OSPFv3, use the following command.Command Mode Descriptionipv6 ospf cost <1-65535> Interface[VLAN] Configures an interface cost for OSPFv3ipv6 ospf cost <1-65535> in-stance-id <0-255>To delete a configured interface cost for OSPFv3, use the following command.Command Mode Descriptionno ipv6 ospf cost Interface[VLAN] Deletes a configured an interface cost for OSPFv3.no ipv6 ospf cost instance-id<0-255>12.3.3.2 Routing Protocol IntervalThe following lists are sort of time interval which can be configured by user:• Hello IntervalOSPFv3 router sends Hello packet to notify existence of itself. Hello interval is thatpacket transmission interval.• Retransmit IntervalWhen router transmits LSA, it is waiting for approval information come from receiver.In this time, if there is no answer from receiver for configured time, the router trans-mits LSA again. Retransmit-interval is configuration of the time interval betweentransmission and retransmission.• Dead IntervalIf there is no hello packet for the configured time. The router perceives other router isstopped working. Dead interval is configuration of the time interval which perceivesother router is stopped operating.• Transmit DelayWhen a router transmits LSA, the traffic can be delayed by status of communications.Transmit delay is considering of the configuration for LSA transmission time.The interval explained as above must be consistent across all routers in an attached net-work.To configure a Hello interval, use the following command.Command Mode Descriptionipv6 ospf hello-interval <1-65535> [instance-id <0-255>]Interface[VLAN]Configures a Hello interval in the unit of second.1-65535: interval value (default: 10 seconds)i
