Passing the value of Tag Sw(config)#vlan 201 Before the DAI is deployed , if the ARP spoofing behavior occurs on the intranet , for example, the PC sends an invalid ARP packet, the switch cannot detect and defend the defensive action. Experimental example: Calling in the distribution list ? Show pvlan mapping Mode Show run | in route One point and one asterisk, match all, any We found R4 on the R3 passed over 100.0.1.0 this route, AS_PATH to 100 100 , from R5 over is 200 , apparent from R5 to the routing AS_PATH shorter, it is preferred by R5 to R2 route. Port Unicast Update ? [Experiment 6 ] There are subnet routes,ccnp r&s course outline, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. Redirection enabled Next Hop Bgp bestpath as-path ignore RFC1721 CLUSTER_LIST is a string passed the route the route reflector cluster ( Cluster ) of the ID , the AS each route in the cluster has a reflection 32bit Metric AS_PATH is a recognized attribute that describes the sequence of AS numbers that will pass through to the destination network . The most important role is anti-ring. If the BGP speaker finds that its AS number is located on the route received from the external peer, the route is ignored. Origin IGP, metric 0, localpref 100, valid, internal, best The configuration of R2 is as follows: CISCO Private Agreement DMZ-Link Bw 193 kbytes is an extended community attribute, so if you want to pass this value to the just IBGP neighbor in the AS , you need to add send-community and add the extended keyword. IP CEF switching turbo vector Generally seen between switches or between switches and routers and servers Now we consider that when R1 originates an OSPF internal route, both R2 and R3 can learn this route. Then on R2 , the route is re-released from process 1 to process 2 , and finally R3 will learn the route from R4 . So for R3 , the dual OSPF process, The configuration is as follows: The vocation of the router is to maintain the routing table and use the routing table for data forwarding. The routing table contains routing entries or routing entries learned through various channels. The simplest and most straightforward method is to use static manual configuration to create routing entries for the router. This method is the most direct and controllable. The highest, the most simple configuration. In a small network, there seems to be no problem with static routing on the whole network. However, in a large network, if you use static routes purely, the workload is very large, not only the workload is large, but another more important defect is Static routes cannot be adjusted according to changes in network topology. Therefore, in large-scale networks, we often use static + dynamic routing protocols to complete route deployment.
