Router redirection Automatic tunneling: The tunneling mechanism of ISATAP is also automatic. The tunnel is created between the host and the ISATAP router. The host prefers to know the IPv4 address of the ISATAP router . Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 , then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing, and the R2 is no longer to R3 updated RIP 's ISATAP address format: The IPv6 address assigned to the ISATAP router is a global unicast address,cisco ccna 200-125 dumps pdf, and the prefix of this address will be used by the ISATAP host for its own IPv6 address construction. ISATAP host through the IPv4 established ISATAP from the tunnel ISATAP receives the message sent by the router / 64 of the IPv6 prefix and the prefix used in conjunction with "special interface identifier" to construct its own IPv6 address.
