Client-Side HP EFS WAN Accelerator
Attached to an Inside Router
In this deployment, PBR is enabled on the router interface connected to the Layer-2
switch that redirects traffic to the HP EFS WAN Accelerator. The same PBR rules
should not be enabled on the WAN router (or any other router on the way to the WAN).

Basic Steps
(Client-Side)
Perform the steps for “Basic Steps (Client-Side)” on page 56. Make sure that you
configure different PBR rules for the second router.
Basic Steps
(Server-Side)
Perform the steps for “Basic Steps (Server-Side)” on page 57.
PBR Between VLANs
If there is not a clear physical separation between the client and the HP EFS WAN
Accelerator on the router where PBR is defined, you can use Virtual Local Area
Networks (VLANs) to create a virtual separation.
In the following figure, the HP EFS WAN Accelerator is configured in a different
VLAN than the client VLAN, and PBR is enabled on the client VLAN interface and
disabled on the HP EFS WAN Accelerator VLAN interface.
