When the valueargument is set to 0, the duplicateaddress detection is disabled.Configuring the NS IntervalAfter a device sends an NS message, if it does not receive a response within a specific period, thedevice will send another NS message. You can configure the interval for sending NS messages.Follow these steps to configure the NS interval:To do… Use the command… RemarksEnter system view system-view —Enter VLAN interface view interface interface-typeinterface-number —Specify the NS interval ipv6 nd ns retrans-timer value Optional1,000 milliseconds by default.Configuring the neighbor reachable timeout time on an interfaceAfter a neighbor passed the reachability detection, the device considers the neighbor to be reachable ina specific period. However, the device will examine whether the neighbor is reachable again when thereis a need to send packets to the neighbor after the neighbor reachable timeout time elapsed.Follow these steps to configure the neighbor reachable timeout time on an interface:To do… Use the command… RemarksEnter system view system-view —Enter VLAN interface view interface interface-typeinterface-number —Configure the neighbor reachabletimeout timeipv6 nd nud reachable-timevalueOptional30,000 milliseconds by default.Configuring a Static IPv6 RouteYou can configure static IPv6 routes for network interconnection in a small sized IPv6 network.Follow these steps to configure a static IPv6 route:To do… Use the command… RemarksEnter system view system-view —Configure a static IPv6 routeipv6 route-static ipv6-addressprefix-length [ interface-typeinterface-number]nexthop-addressRequiredBy default, no static IPv6 route isconfigured.
