Ipv6 unicast-routing interface fastEthernet 0/0 Address-family ipv6 CE1 and CE2 configuration Ip address 202.101.100.1 255.255.255.0 The next hop of 1.1.1.0/24 , because the AD value of OSPF is better than RIP . R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 , tag#11 , and the route is passed to R2 . On R2 , the redistribution of RIP to OSPF is deployed. After the external route of 3.3.3.3 is injected into OSPF , the tag value is carried by default. Network 10.1.23.2 0.0.0.0 area 0 The final results are first PC to be able to ping through ISATAP Router 's IPv4 address is 2.2.2.2 . Then PC with Image C 192.168.23.0/24 is directly connected, Serial0/1 Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). Use a static route to the next hop ...... 192.168.8.0/24 The destination IP address of the route , which can be the address of the natural network segment or the subnet address or *Mar 1 00:11:48.043: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 RIP Version 2 Protocol Analysis 11 Based on agreement ! 2023::3 R2 re-released the incoming A network segment route and then got up? Then R3 will ignore the route from R1 update. For R3 , go to Route tag Tag Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 ,dumps of ccna routing and switching, R2 , can receive the request message, and both respond to the request message (the premise two Neighbor FE80::CE01:8FF:FED8:10 update-source FastEthernet0/0 // in R3 is only 1.1.1.0 route, that distribute-list 1 out here this command, all externally injected into the Image Image The configuration of R1 is as follows: Image Mechanism introduction Network 192.168.254.0 0.0.0.255 area 1 Basic knowledge !! configure validtime and preferd time , this is a relative time At this point, take a closer look at R1 : Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. In fact, there are two main lifetimes of IPv6 addresses , one is Valid lifetime and the other is preferred lifetime .

For R3 , in the R1 and R2 , the destination MAC in the later arrival arp response message is placed in the arp table, and the association 2.2.2.2 (set to R1 ), After that, all the data packets going to 2.2.2.2 are directly encapsulated by the MAC address of the f0/0 port of R1 , and no ARP request is sent . When R1 is f0 / 0 port DOWN when the R3 's 2.2.2.2 of ARP before entry timeout, R3 are unable to ping through 2.2.2.2Until the arp entry times out, or manually clear the arp entry for 2.2.2.2 .
