HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 deployment guide (AG421-96001, March 2007)

66 6 - POLICY-BASED ROUTING DEPLOYMENTS
Symmetric Deployments with PBR,
Auto-Discovery, and CDP
In the case where clients and servers are on both sides of the WAN, PBR can be
configured on both sides of the network where each router has the reversed rules of the
other router.
Figure 6-8. Symmetric HP EFS WAN Accelerator Deployments with PBR
For this example, assume that clients, servers, and HP EFS WAN Accelerators are all
on a separate VLANs and the Layer-2 switch is attached to the router fastEthernet0/
0 interface. This example uses the following IP addresses:
 Left-side. Clients=10.0.1.0/24, Servers=10.0.2.0/24, HP EFS WAN
Accelerator=10.0.3.0/24
 Right-side. Clients=10.1.1.0/24, Servers=10.1.2.0/24, HP EFS WAN
Accelerator=10.1.3.0/24
Each router is connected to the WAN through their Fast Ethernet 0/1 interfaces. They
use the following IP addresses:
 Left WAN = 10.0.4.0/24
 Right WAN = 10.1.4.0/24
To configure the HP
EFS WAN Accelerators
1. On the left HP EFS WAN Accelerator, at the system prompt, enter the following
set of commands:
Left-SH > enable
Left-SH # configure terminal
Left-SH (config) # in-path enable
Left-SH (config) # in-path oop enable
Left-SH (config) # in-path cdp enable
Left-SH (config) # interface in-path ip address 10.0.3.2 /24
Left-SH (config) # ip in-path-gateway inpath0_0 10.0.3.1
Left-SH (config) # write memory
Left-SH (config) # restart
