Ipv6 router rip RIPprocess exit The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. Dynamic routing protocol port number or protocol number Exit-address-family Image IGRP for OSI networks Metric for redistributed routes Mobile routes Use MD5 with BGP4+ After 10.1.31.0 is passed to R2 , since R2 takes the mask of the receiving interface and finds that 10.1.31.0 has a position of 1 in the host part , the subnet is stored in the routing table and treated as a host route. : 10.1.31.0/32 This RS message via IPv4 tunneling, the outer layer is the IPv4 header, source address ISATAP the IPv4 address 1.1.1.1 , the destination address is 2.2.2.2 , which is ISATAP of IPv4 addresses. The IPv4 header is wrapped with IPv6 packets. The source address is the ISATAP host. Image !

This IPv6 address space will be used for the intranet. . We see FIG above, in fact, using 6to4 automatic tunneling, IPv6 islands can either use the 6to4 IPv6 address space, may be used an ordinary IPv6 address space above figure,cisco ccna simulator, Rl hanging IPv6 islands using 6to4 address space R3 on The IPv6 island is also a 6to4 space, and the 6to4 router on the Internet of R2 is also connected to the IPv6 Internet and IPv4 Internet, so he has the IPv6 public network path.
