Now we are going to start backing up the configuration fileWhat we must do before we make a backup: Ping the connectivity of the device, make sure the device is able to communicate properly, we will s

Problem description You can define your own rules for routing packets, not just the destination address. Over here You can learn how to use policy-based routing to solve this problem. In a specific application, policy-based routing is: ☆ Policy Routing based on source IP address ☆ policy-based routing based on packet size ☆ application based policy route ☆ Balancing load by default route Here, the first scenario is described in the routing strategy. Example In this example, the role of t

Cisco single-ARM routing configuration One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q. The difference between dot1q and IS

Switch configurationIt plays an important role in the network topology. It not only connects to the same type of network, but also acts as an interconnection between different types of networks. Therefore, vswitch configuration is a very important link, but basicCommandThe statement is the basis for implementing the switch configuration. The following describes the Cisc
