1.6 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 a FIN packet is received, the IPv6 TCP
connection status becomes TIME_WAIT. If other packets are received, the finwait
timer is reset from the last received packet and the connection is terminated after
the finwait timer expires.
Size of the IPv6 TCP sending/receiving buffer.
Follow these steps to configure IPv6 TCP properties:
Enter system view
Set the finwait timer of
IPv6 TCP packets
Set the synwait timer of
IPv6 TCP packets
Set the size of the IPv6
TCP sending/receiving
buffer

1.7 Configuring IPv6 FIB-Based Forwarding

With the caching function of IPv6 FIB enabled, the device searches the FIB cache
when forwarding packets, thus reducing the time in searching IP packets and improving
the forwarding efficiency.
