Configure 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.

Configuring a Static IPv6
Route
You can configure static IPv6 routes for network interconnection in a small sized
IPv6 network. Compared with dynamic routes, static routes save bandwidth
significantly.
IPv6 network. Compared with dynamic routes, static routes save bandwidth
significantly.
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.
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 FIN packets are received, the IPv6 TCP
connection status becomes TIME_WAIT. If other packets are received, the
finwait timer is reset from the last packet and the connection is terminated
after the finwait timer expires.
