peer-to-peer physical port should support the trunk ports of these two VLANsNote: In Linux, to establish a VLAN first, and the VLAN and the physical port bundle, the switch is two layer exchange, processing is a data frame, so as long as the previous two steps to achieve the same VLAN data exchange. In this example, adding a gateway is using this Linux as a three-tier interchange.Two. Linux acts as a router configuration1. Under Linux, turn on soft route forwarding1. Modify the configuration fi

TelePresence is an innovative technology that connects people, locations, work, and life events through the network to provide a unique face-to-face experience. The high bandwidth of constant data packets produced by telepresence is difficult for some routers and switches to handle. This may be the final accident of a true online App. Therefore, this issue deserves an early investigation. Let's take a look

hardware and allocated by the NIC manufacturer, and has been fixed to the NIC. Generally, it cannot be changed. The IP address is usually automatically assigned by the network administrator or the system. 3) Traditional vswitches can only split up conflicting domains, but cannot split up broadcast domains. vrouters can split up broadcast domains. The CIDR Block connected by the vswitch still belongs to the same broadcast domain. broadcast packets are transmitted across all CIDR blocks connected

Startup Process of cisco routers and switches: I. cisco switch startup process: The START loader is a small program stored in NVRAM and executed when the switch is started for the first time. ① The vswitch loads the loader software from NVRAM. ② Start the loader. ③ Perform POST (self-check on startup) for the low-level CPU subsystem ). ④ Initialize the Flash file system on the system motherboard. ⑤

table, the IP packet is directly encapsulated into a frame according to the table entry, with the corresponding header.② If the table entry for the IP address does not exist in the ARP table, then the router sends a broadcast frame, sets the destination MAC address of the frame header to Ffffffffffff, and after the switch receives the frame, it discovers that the destination MAC address is FFFFFFFFFFFF, The frame is forwarded from all ports except the one that sent the frame, and when the compu

Hubs, bridges, switches, and Routers Luo Weifeng 2011-5-26 These concepts are certainly unfamiliar to people engaged in computers. However, it is easy to make people confused. On the one hand, I will share my views with my superficial knowledge. note: here, I said that the router works at the network layer and does not mean that it does not have the upper-layer infrastructure such as the application
