Configuring the NS Interval
After a device sends an NS message, if it does not receive a response within a specific period, the
device will send another NS message. You can configure the interval for sending NS messages.
Follow these steps to configure the NS interval:
To do...
Enter system view
Enter VLAN interface view
Specify the NS interval
Configuring the neighbor reachable timeout time on an interface
After a neighbor passed the reachability detection, the device considers the neighbor to be reachable in
a specific period. However, the device will examine whether the neighbor is reachable again when
there is 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...
Enter system view
Enter VLAN interface view
Configure the neighbor
reachable timeout time
Configuring a Static IPv6 Route
You 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...
Enter system view
Configure a static IPv6 route
Configuring IPv6 TCP Properties
The IPv6 TCP properties you can configure include:
synwait timer: When a SYN packet is sent, the synwait timer is triggered. If no response packet is
received before the synwait timer expires, the IPv6 TCP connection establishment fails.
finwait timer: When the IPv6 TCP connection status is FIN_WAIT_2, the finwait timer is triggered.
If no packet is received before the finwait timer expires, the IPv6 TCP connection is terminated. If
