A bridge deployment is one method of deploying a BIG-IP® system directly in the path of traffic, such as between a WAN router and LAN switch. In bridge mode, the BIG-IP system is transparent on the network, and the system optimizes traffic using a single bridge self IP address. This configuration allows the BIG-IP system to bridge the LAN and WAN subnets, and requires no changes to the router configuration.
This illustration shows a pair of BIG-IP® systems in a bridge deployment (Site B) on one side of the WAN, and a one-arm deployment on the other side.
Before you configure an iSession™ connection on the BIG-IP® system, make sure that you have completed the following general prerequisites.
If you are configuring a BIG-IP® system in bridge mode, you configure two VLANs and a VLAN group, and then associate a self IP address with the VLAN group.
For example, you can type ffff:ffff:ffff:ffff:0000:0000:0000:0000 or ffff:ffff:ffff:ffff::.
Option | Description |
---|---|
LAN VLANs | Select the VLANs that receive incoming LAN traffic destined for the WAN. |
WAN VLANs | Select the VLANs that receive traffic from the WAN through an iSession™ connection. |
After you complete the tasks in this implementation, the BIG-IP® system is configured in a bridge deployment. For symmetric optimization using an iSession™ connection, you must also configure the BIG-IP system on the other side of the WAN. The other BIG-IP deployment can be in bridge, routed, or one-arm mode.
