Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the
Introduction after you log in to the CISCO switch, we will need to use some common operations, such as querying, restarting, and so on, where some of the commonly used operations are grouped together. Query HelpIn different modes, we can enter the question mark directly (? You can query all the commands that you can use in the current mode. When entering a command, if you do not remember the full name of the command, enter the first few characters
LAN is not changed, and the configuration and access control list of the external network Port WAN needs to be changed .Increase the configuration of the VPDN. Assuming the username is admin, password 123456, the configuration process is as follows:This case is XX Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2600 router (dual Ethernet port), IOS 12.2 (), can realize LAN sharing Internet. This case configuration is divided i
Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP

The Cisco layer-3 switch is another core switch developed by Cisco. It aggregates the bandwidth of the backboard of the switch that is stacked together, in this way, the total backplane of the switch stack is the sum of the bandwidth of several stack switches.
Note that not only the ports used are different, but the cables used are different: the cascade ports mu

The port priority discussed, the bridge priority is a two-byte (16-bit) value, an unsigned 16 is an integer with 216 possible indications, and the range is 0-65535. The default bridge priority is the median value of 32768, which is described using the 10 binary. Note:This book
I came back again, the last two articles introduced the Huawei Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.First, the topological environment:650) this.width=650; "Src=" Http://s2.5

One of my customers has a VPN which I 'd like to access. they provided me with a copy of the Cisco VPN Client for Linux, and a "PCF" configuration file for the client. here's what I had to do to get the Cisco VPN Client working in Linux-and it does work just fine.
