• 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 non-FIN packets are
received, the finwait timer is reset upon receipt of the last non-FIN packet and the connection is
terminated after the finwait timer expires.

Configuring IPv6 FIB load sharing
When the IPv6 FIB caching function is enabled, the device searches the FIB cache for forwarding packets
to reduce the searching time and improve forwarding efficiency.
In the IPv6 FIB load sharing mode, the device can decide how to select equal cost multi-paths (ECMP) to
forward packets. The device supports the following load sharing modes.
• Load sharing based on the HASH algorithm: An algorithm based on the source IPv6 address and
destination IPv6 address is adopted to select an ECMP route to forward packets.
• Load sharing based on polling: Each ECMP route is used in turn to forward packets.
Follow these steps to configure the IPv6 FIB load sharing:
