In the process of ospf, there are two network commands: 1, advertise the route of the network address segment. The mask length i

Recently, I searched for the Cisco simulator on the Internet and found that many netsim 7.0 for ccnp attack patches and replacement files are available for download. Therefore, I cannot download them urgently. The result is:1. download the latest version of boson: 7.06 and 7.02 is hard to find;2. Replace the file with 7.02.3. Although the patch is declared to be used only in version 7.02, the application

Here we will give a brief explanation of the problem of Cisco Route DHCP configuration. Some friends may not know much about it, and most people do not know about the computer, so the customer asked us to allow any computer to access the LAN to access the Internet, so there is a process of configuring DHCP 2600. 2600 router we identify as: Cisco enters global mod

Note: PBR was previously a major tool used by Cisco to discard messages. For example, set interface null 0, which, according to Cisco, would save a bit more overhead than the ACL's deny. Here I remind: Interface NULL 0No IP unreachable//Join this commandThis avoids the return of many ICMP unreachable messages because of the large number of packets discarded. When a three-tier device forwards a packet base

As a pioneer in Internet and IP network infrastructure, a leading company in the fields of ATM, frame relay, communication information management, and Quality of Service (QoS), Cisco is the only company capable of building an intelligent multi-service network, it gives enterprises great flexibility to adapt to the changing business and needs.Core of Cisco IG

As we all know, to obtain a high network duration, you need to use a master router and a backup router with a hot fault recovery function and different network paths. But this is not enough. Routers themselves, especially those on insecure WAN edges, should be equipped with internal redundant hardware components, such as switching matrices, line cards, power supplies, and Route Processor RP ). High-availability routers must also support fast software

Cisco Route Protocol RIP v2 (1)This is not repeated. The one I made is RIP Version1. This is RIP Version2. If it is written into an article that is too long, it will be written separately.* Note: This article is intended for the majority of users to learn. Some of them will mention some professional Internet terms or abbreviations. If you do not understand the network, you can learn and explore it together.

The networking features of Cisco Route are essential for a network to communicate normally. Cisco routers interconnect different networks to make more efficient use of network resources, it brings great convenience to your life and work.I. Network isolation 1. With the development of the network, security has begun to attract people's attention. To improve networ

Only after successful RPF detection can multicast traffic be correctly forwarded in the network. When you query the keyword "cisco rpf detection mechanism and working principle" in baidu or google, we can easily obtain the following principle: RPF check principle: t
