Ieee802.1s is used to resolve excessive spanning tree problems. There are two meanings of configuring pvst+: 1. Using pvst+ to achieve Network Load Balancing 2. Configure the speed port "Enable speed port will save 30S of forwarding time delay"1. Let's do an experiment to verify. First of all, we still build the topology diagram in the virtual machine GNS3, and mark all the parameters that are needed. Such as:2. Although this topology is simple, let'

I. Overview: Today QQ received a friend's help, the following environment, looked at the ASA configuration, the strategy is full pass, incredibly unable to access, but also puzzled. If the use of GNS3 to build environmental testing, on both sides of the firewall grab packet, found that TCP three times handshake normal, but located inside the firewall issued by the HTTP GET packet is the firewall discarded, with Google input keyword: ASA TCP 2000 S

. Perform the XOR operation on the pseudo _ pad and the successful ID (0x01) to add the new bytes to the encrypted data packet and send it to the server. Therefore, using man-in-the-middle attacks, we can change the transmission data and access permissions (identity authentication and authorization) of any user who uses invalid creden. In addition, we can bypass the authentication process for a special user ("enable" password) on a Cisco device. To facilitate man-in-the-middle attacks, I wrote a

Summary of the project's network protocol configuration instructions is over. You can learn a lot through the project ~ In addition to coding algorithm skills, you can also learn to use the GNS3 simulator to build a network environment. The protocols used in the entire process are summarized as follows (for your future use, you can leave the audience to bypass ~~ Ps: Cisco device ): no ip domain-lookup [no DNS resolution] line console 0 [enable consol

. 1. 0/24? 192. 168. 1. 0/24? Originally, we wanted to use gns3 to solve the problem. The Rogue's damn vps and gns took up too much cpu resources, but r2 never received the ip add allocated by r1. The rogue could only configure one, the packet tracer cannot even input "/24" as the mask, and I takes the packet tracer.

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so that VLAN10 and VLAN20 members can obtain IP addresses through the DHCP server. Tutorial procedure IP address planning VLAN10: 192.168.1
