ASA/PIX: Load balancing between two ISP-options VERSION 7 Is it possible to load balance between two ISP links? Does the ASA support PBR (Policy Based Routing )? Does the ASA support secondary IP address on interfaces? What other options do we have? SLA RouteTracking PBR on the router outside the firewall Allowing outb

1. Introduction to Keepalived Keepalived is an important underlying tool that provides HA. Its initial role was to provide HA functions for ipvs and a service software that can provide vrrp health-check functions, it can be used only to provide a floating vip (vrrp virtual routing function), which can easily implement a Hot Standby High Availability function. At the same time, we can also use the LVS + Keepalived architecture based on the complete open source software to provide you with a

the valid address list will soon be insufficient. In this case, you can use the upper-layer protocol id, for example, you can use the port number field of the transport layer TCP/UDP to create a NAT translation table.Ii. Server Load balancer DNS's Server Load balancer technology mainly uses the round robin algorithm. However, the DNS load technology is hard to s

WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use F5 and other devices, software generally use Apache to achieve. Here's how to use Apache. WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use F5 and other devices, software generally use A

Chapter 2 Classification of route selection protocols RIP V2 features Basic configuration of RIP v2 RIP v2 implements VLSM Division (Variable Length subnet mask) Summary of CIDR routes implemented by RIP v2 RIP 2 implements load balancing with equal hop paths RIP2 authentication Configuration RIP2 configuration passive interface to suppress route update ~~~~~~~~~~~~~~~~~~~~~~~~~~~ RIP 2 implements

, you only need to add: Iptables-I RH-Firewall-1-INPUT-d 224.0.0.18-j ACCEPT 2. If you use a script to configure a firewall, add the following rules: Iptables-a output-o eth0-d 224.0.0.18-j ACCEPT iptables-a output-o eth0-s ACCEPT-j ACCEPT iptables-a input-I eth0-d 224.0.0.18-j ACCEPT iptables -a input-I eth0-s 224.0.0.18-j ACCEPT 5. Summary Keepalived implements dual-machine Hot Standby through virtual routing, which is superior to other solutions. Because it is a fixed master-slave Hot

-slave mode is used for data synchronization. Sqlrelay solves connection pool problems and implements Load Balancing for read/write splitting. Sqlrelay is configured with three instances A/B/C. A is responsible for reading data from Master and slave, B is responsible for writing data, and only writes data to Master. C is the router and is responsible for applicat

1. when multiple paths exist at the destination, and the metric values of multiple paths are the same, the equivalent load balancing can be performed, 650) this. width = 650; "src = ".. /attachment/201210/171627301 .jpg" border = "0" alt = "" data-pinit = "registered"/> after completing the configuration, view the neighbor table, topology table, and route table a on R1. neighbors table 650) this. width = 65

Keepalived + HAProxy implements the configuration of MySQL high-availability load balancing, keepalivedhaproxy Keepalived Because mysqlcluster is used in the production environment, high-availability load balancing is required. keepalived + haproxy is provided here. Keepalived is mainly used to implement fault isolatio
