192.168.61.128 as the remote server IP address of GNS3, perhaps everyone is more curious about the configuration of the address there is no need to pay attention to the place, the answer is there, as long as the IP address to the IOU virtual machine IP address.In fact, this place is currently reserved for IOU settings. You can simply think that GNS3 can not only use the local dynamips as iOS running server, it can also designate a remote UNIX virtual

Work Assignment DescriptionA company has purchased a Cisco Catalyst 2950 Switch to build a small local area network that implements the basic communication capabilities of th
I. Overview:
Cisco routers have a lot of IKEV2 for the IKEV2, so you can configure them with little configuration.
Two. Basic ideas:
A. Configure flex VPN on both sides in a svti manner
B. No dynamic routing, configuration of static routes, if one side with Dvti, you need to configure static routes on both sides
Three. Test topology:
Four. Flex VPN

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging the server is not allowed. In this case, an

If the switch is running Cisco Catalyst 1900/2820 Enterprise Edition software. You can change the configuration by using the command control port (command-line interface CLI). When you enter the

Background requirementsThe Cisco two switches need to be virtual into a single switch (similar to a switch stack), to link two-tier access switches, and to provide high availability of network links. Such as: For the two-layer switching 2960x needs to see the upper two n3k switches for a single device, the intermediate connection link does the link aggregation.Second, configuration detailed n3k_1 and
With the development of the international interconnection Network, some enterprises have established their own intranet and connected with the Internet through a dedicated line. In order to ensure the security of intranet, it is necessary to use dedicated firewall computer to prevent illegal intrusion. The router firewall can only be used as a filter and cannot hide the internal network structure from the intruder's eyes. As long as a computer on the external network is allowed to directly acces
