Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. Multi-vendor routing environment Interface Tunnel1 The configuration of P is as follows: When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 The source address of the RA packet, whether it is a linklocal address Becomes 24 bits, appears in HELLO package, DBD package, and router LSA , network LSA , interAreaRouter LSA , Link LSA Neighbor FE80::CE02:8FF:FED8:0 activate Ip route 0.0.0.0 0.0.0.0 192.168.23.3 8 bits Interface FastEthernet1/0 Weight Use a hold-down timer to prevent routing loops Ipv6 address 2001:1::FFFF/64 ipv6 nat :: abcd / 96 (front 96 th 0 , keep the back abcd is the IPv4 address) Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 If you do the following configuration on R2 : Experimental needs PC1 configuration: When 10.1.1.2 is reachable, the track object is true Isis circuit-type level-1 interface Serial0/1 Ospf rip static Match interface s 0/0 RIP and OSPF R1(config-router)# redistribute connected subnets Image Tunnel mode gre ip In the above figure, there is a problem with the network on the left side. The L2 router of the IPv4 single protocol does not support IPv6 ,free ccna 200-125 dumps, thus destroying the continuity of the IPv6 L2 router . The network on the right is the correct structure. R3 sets the tag when injecting the route. If it is RIP , the network specified by the ip default-network command does not need to be displayed to announce RIP , and once the default gateway is specified, RIP ? ACL Stateless address autoconfiguration Nolabel/403 The 64btis interface identifier generated by the ISATAP host and the ISATAP router can be further used to construct the tunnel interface.

At this point, take a closer look at R1 : Tunnel source serial 0/0 tunnel destination 10.1.23.3 The transition from an IPv4 single-protocol network IS-IS router to an IPv6-IPv4 router is critical. If the adjacency check is not turned off during the transition (turn off the adjacency check, use no adjacency-check ), IPv4 single protocol Wang Liping IS The -IS router will refuse to form adjacencies with the IPv6-IPv4 router. After a successful transition, when all IS-IS routers support both protocols, the no adjacency-check command can be removed .
