, but the IP address is in the port settings, HSRP does not run on any device. If it runs, it is not necessarily the active port. Instead, the IP address set on the port is always desirable and reliable, and the IP address is the most reliable.
Lab Note: Packet tracert cannot perform HSRP experiments. Only dynami or gns3 can be used.
The basic topology is as follows:
Note:
Hot Standby is performed on ports F0/0 of R1 and R2, and no hot standby is p

We recommend Mainline over technology train if you is interested on stability without the need of new features. Please see the
Frame Relay is a connection-oriented two-layer packet switching technology, the core idea is to use a unique DLCI (link identifier) number to build a virtual channel to the destination, when the packet is forwarded, through the DLCI to select the path. It is a network technology that differs from the two layer Mac switching technology and the three layer IP routing technology.Three basic terms:PVC: Permanent virtual link, virtual link is established permanently, its performance in the carrier an
Objective:Share with me today a Cisco integrated small experiment, difficulty CCNA level. It mainly involves the following knowledge points: VLAN, DHCP, STP (spanning-tree) +HRSP (standby), OSPF, NAT, ACL. The GNS3 simulator is used in the experiment. The experiment is as follows:Experimental Purpose:The ultimate experiment was designed to allow the PC to access the R2 loopback interface (the Internet is being emulated here). Specific implementation d
Since the use of GNS3, it is not how to use Packet Tracer, today took packet tracer to do a terminal access to the server experiment, feel packet tracer more powerful than we think, it seems to be a good study ah.Let's start by introducing what is Cisco's Terminal server. When we do experiments with more than one switch or router, it is very inconvenient to unplug the console line often. The terminal access server is a router with 8 or 16 asynchronous
In this article, I'll briefly explain the Active/standby failover configuration on the Cisco ASA. The lab is do in GNS3.

I. Overview:
QQ Group of a Netizen consulted three places through the MSTP line 22 interconnection, are Cisco equipment, but one of them does not support OSPF, ask if the normal situation, the data to go 8M line, but the 8M link problems when the 4M backup link, and then use GNS3 to build the environment test a bit, Brush up on the SLA settings.

A. Static routing priority dynamic OSPF routing, static routing configuration of diffe

Dynamips is a Cisco router emulation software.Installation process:git clone git://github.com/GNS3/dynamips.gitcd dynamipsmkdir buildcd buildcmake ..For MacOS, CMake and libelf need to be prepared.If you encounter an error:CMake Error at /usr/local/Cellar/cmake/3.10.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find LibElf (missing: LIBELF_LIBRARIES LIBELF_INCLUDE_DIRS)is not found LibElf library, can be installed
Three VLANs are divided, and three VLANs will be made separately from each other.The PC3 will be used as a DHCP server to provide IP addresses for different VLANs,PC1 and PC2 will automatically get the IP address of the corresponding VLANAfter first configuring SW1 and SW2 with the three-layer switch principle, you also need to configure the "helperaddress" statement in SW1 to match the gateway to the specified DHCP server.Open the Linux system and match the IP address to the DHCP server in the

MPEG4 defines a system decoding mode (SDM). This decoding mode describes an ideal decoding device for processing the syntactic semantics of bit streams. It requires special buffer zone and real-time mode. Through effective management, we can make better use of limited buffer space.
④ Audio Encoding
The advantage of MPEG4 is that it not only supports natural sound, but also supports sound synthesis. The audio part of MPEG4 combines audi
