Cisco router reset enable password tutorial, ciscoenable
Steps:
1. Restart the vro and press ctrl + Breack when ROM Monitor mode appears on the vro to enter ROM mode, for example:
2. Modify the vro register value, change the original register value 0x2102 to 0x2124, and then run the reset command to restart the device, for example:
3. After the password i
is based on TCP, ldp can establish a session across the network without direct connection. (2) Establishment of TCP connection (3) establishment of LDP Session (4) Distribution of labels different interfaces on the same vro can enable the ldp or tdp Protocols respectively, both ldp and tdp protocols can be enabled on the same interface. next, we will use an actual implementation example to explain the principle of
At present, Edge Routers are widely used, and there are also many problems. So I studied the security of MPLS-based VPN technology in Edge Routers, I would like to share it with you here and hope it will be useful to you. If an enterprise deploys a Multi-Protocol Label exchange MPLS) managed Virtual Private Network VPN (VPN) service, it will not only get high-quality services, but also greatly reduce costs,
large-scale network construction.
Huawei and Cisco are the main product manufacturers of mpls vpn technology from the current use of routers and switches in enterprise and e-government networks. From the network products of Huawei manufacturers, the corresponding vrouters and vswitches meet the performance requirements. For example, the Huawei vronene80/40/16/08/05 can be P/PE, and the S8016 layer-3 vswitc
Cisco is now the world's largest manufacturer of switching routes! Many of our businesses, large and small, can use the network, and it is possible to switch routes to Cisco! When we install network equipment, we may ask the network engineer to help us install it! Access to the router has a lot of passwords! What if we forget these passwords? We may have to make

Note: here we will introduce you to how to use the Configuration Wizard of the Broadband Router to automatically configure. Experienced users can also manually configure the Broadband Router as needed, we recommend that you manually configure the Broadband Router to
TFTP server software on your PC and the file name mentioned in the TFTP server root directory. We recommend that you keep the backup of the router/access server configuration before the upgrade. The upgrade does not affect the configuration (the configuration is saved in non-easy-to-lose RAM (NVRAM ). However, if the operation steps are not correctly performed, the operation may be affected.
For RCP applications, replace each TFTP with RCP. For examp

that you need a user and a password to gain access. In addition, we recommend that you use a secret password for your username, instead of a common password. It uses MD5 encryption to encrypt passwords, and greatly improves security. Example: Router (config) # username root secret My $ Password
After the user name is configured, you must enable the port using the user name. Example:◆
SDM to call a vro that has been configured, you only need to perform one security audit step to evaluate the security advantages and weaknesses of the Cisco vro configuration. The administrator can precisely adjust the original router security configuration to better meet enterprise requirements. In addition, Cisco SDM can also be used for routine operations, su
systems of Cisco router IOS, which may expose sensitive information. This vulnerability allows a low-level user (for example, a user who does not know the 'enable' password) to use the system to view some information, in theory, this information should be visible only to users who know the 'enable' password.

Cisco SDM is a good tool for vro security configuration. It features easy to learn and allows users to easily complete vro settings. Cisco SDM is based on Cisco IOS®An intuitive Web device management tool developed by Software routers.
It simplifies router security configurations through smart wizard, allowing customer

The settings of the DMZ host are the same as those of the virtual server.
