A technology, especially network-centric and communication-centric technology, has its own transmission protocol. Now we will introduce some knowledge about Cisco Unified Communication Protocols. So what is SIP when Cisco's unified communication protocol is used? Why is it used? Support for the SIP protocol in

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

Global debugging When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Dis

1. Start the OSPF protocol To start the OSPF routing protocol on a CISCO router, two steps are generally required:1) Start the OSPF protocol process:Router (config) # router ospf 2) define the network of the vro:Router (config-router) # network The OSPF protocol is started

CDP is short for Cisco Discovery Protocol, a data link layer Protocol. Through this Protocol, our network administrator can obtain information about devices that run the CDP Protocol adjacent to each other. CDP protocol version:

CHAP (Challenge Handshake Authentication Protocol) and PAP (Password Authentication Protocol) are generally used to provide security Authentication on PPP encapsulated serial lines. With CHAP and PAP authentication, each Cisco router is identified by a name to prevent unauthorized access. Task commands Set the PPP encapsulation ppp1 Set the authentication method

understand the RIP Protocol: * Configure the IP address and loopback port first. After completing the configuration before the experiment, we will configure router R1 and use it as an example: R1 # configure terminal // enter the Configuration Mode Enter configuration commands, one per line. End with CNTL/Z. R1 (config) # router rip // start the RIP Protocol R1 (config-router) # version 1 // configure RI

The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Pu
