Image GW configuration In the routing table of R3 , there is only 1.1.1.0 route. Image In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network 8 bits The summary of the route is actually done by the operation of the subnet mask. For the following example: This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 , connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF .

Interface Loopback0 ipv6 enable 192.168.1.0 declares that it has entered RIP , and R3 and R4 can learn this route and load it into its own global routing table. Then if we are at R2 to R1 added IPv4 header removed to restore the original IPv6 data, and then forwarded to the right of the IPv6 PC . Expire prefix at a specific time/date Infinite Valid Lifetime Interface FastEthernet0/0 ipv6 enable Redistribute rip subnets route-map test First, an IPv6 ACL is used to match IPv4-mapped traffic. The above ACL source is an IPv6 only network. The purpose is to Ipv6 enable relay. In this arbitrary play prefix, if the defined IPv4 address of the nearest 6to4 relay is 192.88.99.1 , then the address is First, R2 itself obtains a 6to4 address space through its own IPv4 public address mapping . R2 assigns itself an address in the 6to4 IPv6 address space ( 2002:ce7b:1fc8:1::1 ) so that other 6to4 routers can find it. Yourself. For R1 such a 6to4 router, simply add a default route: Ipv6 route :: / 0 2002: ce7b: 1fc8: 1 :: 1 can be,200-125 dumps, so that R1 is connected IPv6 islands user wants to access non- 6to4 of On an IPv4 network, the data is matched by this default route. The next hop is 2002:ce7b:1fc8:1::1 , which is a 6to4 address, so R1 first obtains its corresponding IPv4 address according to this address: 206.123.31.
