Tunnel tunnel The configuration of CE2 is as follows: ::1 test.com MD5 is certified between R2 and R3 . State Image Interface FastEthernet1/0 Duplicate address detection: The node sends an NS to the Solicited-Node multicast address corresponding to the tentative address that it will use . If it receives the NA of the response from another station , it proves that the address has been used on the network, and the node will not be able to use it. Use the tentative address communication. ! For a comprehensive explanation of IPv6 multicast , please see the "Black Tea Three Cup Multicast Technical Notes" Interface FastEthernet0/0 Experiment 2 The IS-IS domain is based on a two-layer structure, Level1 and Level2 , and the concepts of L1-router , L2-router, and L1L2-router , and IPv4 IS-IS . Redistribute connected route-map test About the prefix list EIGRP Ipv6 address 2001:12::1/64 Configuration example 5 (in the single routing protocol environment - OSPF out direction distribution list) RIP based on rumor updates Test phenomenon: can ping through The configuration of CE1 is as follows: 10.1.12.2 A few notes: B Netsh interface ipv6 add address 21 3ffe::1 unicast !! Assuming that the interface index number to be configured is 21 , this command configures an IPv6 unicast address for the interface . R1(config-route-map)# match ip address prefix-list list1 A quick look at: MAC address. Redistribute routes to the protocol Header format To verify which outbound interface is used for a particular traffic in destination-based load balancing, use Neighbor discovery and adjacency formation mechanisms are the same IPv6 routing !! Two ACLs are created above to match the routes that need to be treated differently. OSPF . In this way, for R4 , it goes to 192.168.1.0 , there is a sub-optimal path , that is, around the long way,ccna practice questions, take R2-R3-R3-R5 Interface fastEthernet 1/0 ipv6 enable 1 : RIP-1 ; Image Experimental needs When a router receives an update from the neighbor router indicating that the previously reachable network is now unreachable, or has a route with a larger hop count, the router marks the route as unreachable and starts a suppression timer if If the router receives a newer update of the route before the timer expires, or has a better metric than the previous record, the router identifies that the route is reachable and deletes the timer.
