12.2.7 ipv6 redirect
Command:
ipv6 redirect
no ipv6 redirect
Function:
Enable IPv6 router redirect function. The no operation of this command will disable the function.
Command Mode:
Global Configuration Mode.
Default Settings:
IPv6 router redirect function is disabled by default.
Usage Guide:
If router A, router B, and node C are on the same network link, and router A forwards IPv6 packets
from node C to router B, expecting router B to continue the forwarding, then router A will send an
IPv6 ICMPv6 redirect message to node C-source of the packet, notifying it that the best next hop of
this destination address is router B. By doing so, the forwarding overhead of router A will be
decreased, so is the network transmission delay of node C.
Examples:
Enable IPv6 router redirect function.
Switch(config)# ipv6 redirect
