Ipv6 nat prefix 2001:2::/96 On the other hand, we capture the package: Image The V4 address pool allows a V6 user to take an address from the pool as a source address after traversing the NAT-PT device. But how do V6 users access the V4 network? Can't let V6 only host ping 202.101.100.2 ? Therefore, you have to add commands to the configuration: Ipv6 address FE80::FFFF:FE10:6 link-local ipv6 router isis RIPng Interface Serial0/0 ipv6 enable Ipv6 install ipv6 if An IPv6 unicast address corresponds to a Solicited-node address. The valid range of the Solicited-node address is the local link range. The configuration of R2 is as follows: Ipv6 address 2001:12::2/64 Ipv6 enable 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . CEF form RIPv1 update and receiving rule verification Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) ............ 100x xxxx xxxx xxxx Match ip address 1 set metric 20 This RS message sent by the ISATAP host will be routed in the IPv4 network and eventually forwarded to the ISATAP router. This will cause the router to immediately respond with an RA : Image Adding the default keyword will cause the interface to install a default route after getting the address through stateless autoconfiguration. V6 v4 protocol conversion Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length 2000::/3 Interface fa1/0 Ipv6 enable R1 Below we summarize some of the key points of the router about route lookup: Prefix readdressing Next Hop R3 AFI (Address family identifier) Dns-server 2000::8 domain-name HelloWord FastEthernet1/0 The O position 1 indicates whether the entry in the NA message overwrites the existing one, and the neighbor who receives the message overwrites the existing entry. 5 Route Distinguisher: 1:1 (cisco) Address-family ipv6 !

Before routing 0bits must 0.0.0.0 ago 0 Ge bit match, in fact, all the bits does not matter, but also for the mask, that did not write ge keyword is implicit so ge 0 Le 32 , that is, cover The code length is greater than 0 and less than or equal to 32 . So this prefix list is permit Must be zero The configuration of R3 is as follows: ! Stateful autoconfiguration Family Identifier ) 192.168.1.0/24 Image Ipv6 address FE80::FFFF:FE10:1 link-local FastEthernet0/0 is up, line protocol is up Address-family ipv6 [Experiment 1 ] Both internal networks use 6to4 addresses (both sides are 6to4 networks) Fa1/0 IPv6 host ( xp system ie6.0 ) accesses IPv6 WEB site In order to get this prefix automatically, just run a protocol between the router and the host. Router using NDP protocol !! View ipv6 interface configuration information OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 2023::2, subnet is 2023::/64 Joined group address(es): Identify the type of message: Expire prefix at a specific time/date Infinite Valid Lifetime Image First B goes to ping 202.101.100.100 , the data packet is as shown.

When the old prefix is ​​completely retired (the lifetime has passed), the router advertisement message only includes the new prefix.
