16.2.4 IPv6 Troubleshooting
The router lifespan configured should not be smaller than the Send Router advertisement
Interval. If the connected PC has not obtained IPv6 address, you should check RA
announcement switch (the default is turned off).
16.3 IP Forwarding
16.3.1 Introduction to IP Forwarding
Gateway devices can forward IP packets from one subnet to another; such forwarding uses
routes to find a path. IP forwarding of switch is done with the participation of hardware, and
can achieve wire speed forwarding. In addition, flexible management is provided to adjust and
monitor forwarding. Switch supports aggregation algorithm enabling/disabling optimization to
adjust generation of network route entry in the switch chip and view statistics for IP forwarding
and hardware forwarding chip status.
16.3.2 IP Route Aggregation Configuration Task
IP route aggregation configuration task:
1. Set whether IP route aggregation algorithm with/without optimization should be used
Command
Explanation
Global Mode
ip fib optimize
no ip fib optimize
Enables the switch to use optimized IP route
aggregation algorithm; the “no ip fib optimize”
disables the optimized IP route aggregation algorithm.
16.4 URPF
16.4.1 Introduction to URPF
URPF (Unicast Reverse Path Forwarding) introduces the RPF technology applied in multicast
to unicast, so to protect the network from the attacks which is based on source address cheat.
When switch receives the packet, it will search the route in the route table using the source
