Document number The metric is a value) DTP enables trunk negotiation between switches Port-Security deployment considerations The configuration of R3 is as follows: 16 bits description 192.168.12.1 A frame whose type field is 0806 represents an ARP protocol frame. Match ip address 1 The src-mac detects the received ARP packet. The source MAC address of the Ethernet pillow is the same as the sender MAC address in the ARP body . This verification action is performed in both the ARP request and the response message. Feature VLAN: At this time, R2ping 1.1.1.1 will pass (equivalent to 172.16.12.1 as the last hop help object) For example , the configuration of R3 is as follows: Let 's take a look at the features of BackboneFast : Router ospf 100 Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 Or the above example, if we R1 on, of ping 1.1.1.2 REPEAT size. 1 1501 ,ccnp switch quick reference, at this time, R1 due to the generation of the IP packet is larger than Static routes Range character example: 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.
