Based on packet load balancing, all packets are rounded on the outgoing link. If you want to use message-based CEF load balancing, you need to configure this command on all outbound interfaces. The buddy experiment has verified that it can indeed be per-packet load balancing. The verification of Layer 2 and Layer 4 is already robust enough, so IPv6 directly cancels the Layer 3 check of IP . After these packets arrive at R1 , the R1 router supports IPv4 and IPv6, which is a dual-stack router. R1 and R2 establish a tunnel to connect two IPv6 islands that are respectively hanged at R1 and R2 . The original IPv6 packet sent by the PC is added with an IPv4 tunnel header by R1 ,ccna dumps july 2018, forming a message that looks like an IPv4 packet. Thereafter, this message is routed in the IPv4 network and eventually reaches R2 . After receiving the "tunnel packet", R2 removes the IPv4 header of the packet and then restores the original IPv6 packet to the IPv6 network.
