Multi-IP virtual servers 编辑

The Citrix ADC supports creating a single load balancing virtual server with multiple non-consecutive/consecutive IPv4 and IPv6 addresses of type VIP. Each VIP address bound to a virtual server is treated as an individual virtual server. These virtual servers have the same protocol and other virtual server level settings. A virtual server with multiple VIP addresses is also called multi-IP virtual server.

The following are some advantages of using multi-IP virtual servers:

• A multi-IP virtual server offloads the work of creating many virtual servers with the same settings and service bindings.
• Multi-IP virtual servers effectively reduces the possibility of reaching the maximum limit on virtual server entities.
• One multi-IP virtual server can be used for clients in different subnets to connect to the same set of servers.
• Only one multi-IP virtual server can be used for IPv6 and IPv4 clients to connect to the same set of servers.

Configure a multi-IP virtual server

Configuring a multi-IP virtual server consists of the following tasks:

• Create an IPset and bind multiple IP addresses to it.
• Bind the IPset to load balancing virtual servers.

Note the following points related to IPset configuration:

• An IPset can have:
  • non-consecutive/consecutive IPv4 addresses and IPv6 addresses
  • combinations of IPv4 and IPv6 addresses.
• All IPv4/IPv6 addresses to be associated with virtual servers using IPset must be of type VIP.
• A single IPset can be bound to multiple virtual servers.
• IPv4/IPv6 addresses can be bound/unbound to/from IPset irrespective any existing IPset bindings to virtual servers.
• You must unset the IPset binding to a virtual server before binding a new IPset to it.

To add an IPset and bind multiple VIP addresses to it by using the CLI

At the command prompt, type:

add ipset <name>

bind ipset <name> <IPaddress1 …>

bind ipset <name> <IPaddress2…>

show ipset <name>
