OSPF can let R3 learn 1.0/24 and 2.0/24 routes. Ipv6 unicast-routing !! Note that to support IPv6 unicast routing protocols, this switch must be turned on. None Unassigned Linklocal address, and IPv6 global unicast address. This will be described below. As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. Ip default-network 172.16.0.0 The NIC is configured with an IP address of 1.1.1.1/24 and the gateway is 1.1.1.54. On the Internet, like R2 such 6to4 relay router still a lot. There are some public 6to4 relays. E.g: Open Shortest Path First (OSPF) Routing Information Protocol (RIP) Route map reference Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd Network 10.1.23.2 0.0.0.0 area 0 I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary The transition mechanism of V4 to V6 discussed above is basically the case where V4 and V6 coexist. So if there is a need for mutual access to the V4 single protocol and the V6 single protocol network? Type echo protocol ipIcmpEcho 10.2.2.2 source-ipaddr 10.2.2.1 frequency 10 Ip address 10.1.12.1 255.255.255.0 In general, the tunnel agent and the dual stack Router belong to the same management party, such as the same company. Because the tunnel agent has the configuration permission of the dual stack Router . Complete the configuration of CE1 and CE2 . 1400 16 bits There are two types of ICMP messages: error messages and information messages. The configuration of R1 is as follows: Under normal circumstances, Rl is possible to ping through 3.3.3.3 , but if R2 f0 / 0 port agent arp turned off, then it ping nowhere outlet associated with the use of static routing, the router will route to the destination address that is the local chain Road,dumps for ccna 200-125, so send arp request for mac of 3.3.3.3 , and None Image Interface loopback0 Network 10.1.23.3 0.0.0.0 area 0 In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network ! 137 Ipv nd prefix default ? If B replies to NA , then the neighbor state on B on A is Incomplete -> Reachable . However, if A does not receive any response within a certain period of time after A sends out the NS message , the entry is deleted by Incomplete->Empty .

For example, in a financial network, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP , and RIP is also re-released to OSPF. .
