2.2.2 Configuring ICMPv6
Redirection
This section will describe how to configure the ICMPv6 redirection function on the
interface. By default, the redirection function of the IPv6 on the interface is enabled.
The router needs to send the redirection message to the source during packet
forwarding in the following cases:
z The destination address of the message is not a multicast address;
z The destination address of the message is not the router itself;
z The output interface of the next hop determined by the device for this message is
the same as the interface this message received, namely, the next hop and the
originator is of the same link;
z The node identified by the source IP address of the packet is a neighbor of the
local router. Namely, this node exists in the router’s neighbor table.
Caution
The router other than the host can generate the redirection message,
and the router will not update its routing table when it receives the
redirection message.
