Redirection

Upon receiving a packet from a host, the gateway sends an ICMPv6 redirect message to inform the host of a better next hop when the following conditions are met:

• The interface receiving the packet is the same as the interface forwarding the packet.

• The selected route is not created or modified by an ICMPv6 redirect message.

• The selected route is not a default route on the device.

• The forwarded IPv6 packet does not contain the routing extension header.
