This article mainly introduces how to upgrade two PCs to a Cisco router IOS. How can we do this? The following article will give you a detailed introduction. I have a 2501 router whose IOS is a bad cisocB), another 2501 router whose IOS is a good (ciscoA), and a good IOS is no longer available on my PC, however, it is a waste of time to create a TFTP file on the PC and upload the file to the PC ,. Then I thought of a way to directly configure the vro

This article mainly introduces the Storage Classification of Cisco routers, as well as four execution modes and password settings for different access methods. I hope this article will help you. Memory category: 1: RAM: Random Access to memory, equivalent to computer memory 2: ROM: read-only memory. Some microcodes used to start and maintain the router are resident in the ROM. 3: FLASH Memory, equivalen

This site has previously shown us the method of segmenting a router into eight virtual routers using virtual Routing and forwarding (VRF, VM forwarding) through a scene example. I showed you how to configure VRF, and in this article we continue to use this scenario and, through IPSec configuration, replicate the exact topology and address to eight experimental environments. The entire environment can proceed smoothly, first requires the virtual route
