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

This article will demonstrate the optimal design of multi-egress for medium-sized data centers through the Cisco IP SLA and EEM, and the data center build background:1, the data center from the ISP applied for a number of export links, this article in three demonstrations, wherein the first 2 is enabled by default, after any one of the failures, automatically enable the third, each connected to the same operator or different devices.2, the main use of

In the process of doing the collector, often encounter the situation of IP restrictions, this time can be switched through the IP can continue to access.If it is a multi-IP server, then you can switch the export IP to achieve.1.

This article describes how to configure dual-address dual-Egress and how to apply NAT configurations. I believe this article will help you. Environment Description: uses the Cisco2621XM + NE-1E module, which has two FastEthernet and one Ethernet port. Now we use Ethernet port 1/0 to connect to the internal LAN, simulating a policy route based on the original address when there are 100.100.23.0 255.255.255.0.0 and 100.24.0 255.255.255.0.0 clients inter

The simplest basic usage of traceroute is: traceroute hostnameThe Traceroute program is designed to utilize the TTL (Time to Live) field (field) of the ICMP and IP header. First, Traceroute sends out a TTL of 1 IP datagram (in fact, each sent out for 3 40-byte packets, including the source address, destination address and Packet issued time la

View the network bandwidth egress of CentOS Check the network port size of the server when maintaining the system. Therefore, a Linux Command is required. How can I check the network bandwidth egress of CentOS? You can use the following command to view details. # Ethtool eth0 The preceding command is followed by the device name. If the external network device is eth1, you need to change it to ethtool
