Chapter 4: Configuring the High-Level Network

To set dynamic connection rebinding from the command

line

To manage dynamic connection rebinding using the bigpipe virtual

command, type one of the following commands.

b virtual <ip>:<service> conn rebind enable

b virtual <ip>:<service> conn rebind disable

b virtual <ip>:<service> conn rebind show

Setting up last hop pools for virtual servers

In cases where you have more than one router sending connections to a

BIG-IP, connections are automatically sent back through the same router

from which they were received when the auto_lasthop global variable is

enabled, as it is by default. If you want to exclude one or more routers from

auto-lasthop, or if the global auto_lasthop is disabled for any reason (for

example, you may not want it for an SSL gateway), you can use a last hop

pool instead. (If auto_lasthop is enabled, the last hop pool takes precedence

over it.)

To configure a last hop pool, you must first create a pool containing the

router inside addresses. After you create the pool, use the following syntax

to configure a last hop pool for a virtual server:

b virtual <virt_ip>:<service> lasthop pool <pool_name> | none | show

Configuring virtual servers that reference rules

Once you have created a rule, you must configure the virtual server to

reference the rule. You can configure a virtual server to reference a rule by

using either the Configuration utility or the bigpipe command.

To configure a virtual server that references a rule using

the Configuration utility

1. In the navigation pane, click Virtual Servers.

The Virtual Servers screen opens.

2. Add the attributes you want for the virtual server such as address,

port, unit ID, and interface.

3. In the Resources section, click Rule.

4. In the list of rules, select the rule you want to apply to the virtual

server.

5. Click the Apply button.

To configure a virtual server that references a rule from

the command line

There are several elements required for defining a virtual server that

references a rule from the command line:

b virtual <virt_serv_key> { <virt_options> <rule_name_reference> }
