ICMP Redirect Messages for IPv6

A new command has been added to enable the switch to issue ICMP redirect messages for unicast IPv6 traffic, as recommended by RFC 2461 "Neighbor Discovery for IP Version 6 (IPv6)". To enable the new function, use the command:

ENABLE SWITCH ACCELERATOR FUNCTION=ICMPREDIRECT

The switch accelerator does not issue ICMP redirect messages. When ICMPREDIRECT is enabled, any unicast IPv6 packet that has the same ingress and egress VLAN is routed in software rather than hardware, and ICMP redirect messages may be generated.

The purpose of an ICMP redirect is to replace layer 3 routing with layer 2 switching. On a layer 3 switch, switching and routing are both performed in hardware, so ICMP redirects offer no performance improvement. The ICMPREDIRECT function may impact performance in particular (unusual) network configurations, and is not recommended for use in a general network environment. The ICMPREDIRECT function is disabled by default.

To disable the ICMPREDIRECT function, use the command:

DISABLE SWITCH ACCELERATOR FUNCTION=ICMPREDIRECT

To see whether the function is enabled or disabled, use the command:

SHOW SWITCH ACCELERATOR
