The R position 1 indicates that this is a router. Router(config)#router rip Routing Information Protocol With the public network address, we also have a 6to4 address space calculated from the public network address : Neighbor 2023::3 activate After getting the 6to4 IPv6 address space, the address space is 16+32=48bits , which is /48 ,ccna topics, so the space is very large, you can further divide the subnet. This IPv6 address space will be used for the intranet. . Used to determine the link layer address of a neighbor, also used for DAD, etc. #源 server Route-map BGP2OSPF permit 20 match ip address 2 Netsh interface ipv6 reset 1/256 Routing? The key point is that R2 , through the R2 deployment redistributed routing , routing information may be selected in different transmission routes between the domains. 6to4.ipv6.microsoft.com and so on. Image technical background The configuration of R1 is as follows Border Gateway Protocol (BGP) Connected This is the general case, of course, there are two situations, it depends on the specific environment and the specific routing protocol. Route tag Tag Se0/0 Router ospf 1 Advertised to update-groups: 1 Timers Interface fast1/0 Ipv6 mtu 1400 Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route The Response packet contains a maximum of 25 routing entries. Image This prefix will not be included in the RA message. By default, CISCO IOS turns off this no-advertise , which means that the prefix will be included in Net 49.0002.0000.0000.0003.00 !! NET entity address Image IGRP Area Address(es): 49.0001 SNPA: *HDLC* On R3 : Ipv6 enable Se0/1 6 Ipv6 route 2002::/16 tunnel1 0xA440 S Ip rip trigger Neighbor request ( NS ) Interface Serial0/0 ipv6 enable Here we use a access-list 1 match 202.101.100.0/24 network, while it with v4v6-pool this IPv6 address pool to do a bundle FastEthernet0/0 The route to the OR2 loopback interface is found . The next hop is FE80::5C10:8CFF:FEE0:FE89 , which is the link-local address of the OR2 interface. In the original Ipv6 environment, an interface often has multiple Ipv6 addresses, and OSPF. The maintenance of neighbor relationships is based on stability. The link-local address that is necessary for each interface becomes the best way to establish neighbor relationships. Why is ping unreachable? Because this is a frame relay environment, FE80::5C10:8CFF:FEE0:FE89 is the IPV6 address. There is no mapping on OR1 , and OR2 is the same. Therefore, the frame of the link-local address of each peer is added. Follow the mapping.
