APPLICATION NOTE - Juniper Networks WX Series Large Deployment with WCCP Off-Path Integration on Cisco
Introduction
In large deployments, one of the Juniper Networks® WX Series Application Acceleration Platforms (or Juniper
Networks WX Stack) at the data center may not scale enough to support the throughput or all the locations.
In that case, the traffic has to be distributed to multiple WX Series (or WX Stacks). There are multiple options to
achieve this distribution, such as WCCP or PBR on routers.
This document focuses on WCCP.
Scope
The goal of this application note is to provide you an understanding on:
• WCCP protocol and its different options
• How to configure WCCP on Cisco
• How to deploy Juniper Networks WX Series with WCCP off-path
Design Considerations
WCCP is a Cisco protocol also available on other network vendors, such as the Juniper Networks WX Series.
Cisco enhanced its WCCP support. We recommend the minimum Cisco IOS release 12.2.33.
Juniper Networks WX Series also enhanced its WCCP support. We recommend minimum 5.4.4 for WCCP Hash mode
and 5.7 for WCCP Mask mode.
Lab
The lab is composed of:
• One Data Center
-- 1 Cisco 6500 router
-- 1 Server
-- 2 Juniper WX Series off-path (4 for high availability, HA)
• Two Branches
-- 1 Client (in each)
-- 1 of the WX Series In-Line (in each)
WCCP redirects traffic to the right WXC Series

Traffic flow:
• Client-Branch1 to Server
-- The Client-Branch1 sends traffic to the Server.
-- The traffic is intercepted by the WXC-Branch1.
-- The WXC-Branch1 sends that flow in its optimized tunnel to the WXC-DC1A.
-- The WXC-DC1A sends the traffic to the Server.
• Server to Client-Branch1
-- The Server sends traffic to the Client-Branch1.
-- The Cisco 6500 redirects the traffic to the WXC-DC1A via WCCP.
-- The WXC-DC1A sends that flow in its optimized tunnel to the WXC-Branch1.
-- The WXC-Branch1 sends the traffic to the Client-Branch1.
Important Technical Points
Juniper Networks WXC Series Application Acceleration Platforms High Availability
At least two Juniper Networks WXC Series (WCCP Clients) per WCCP service have to be installed to provide HA.
The WXC Series can be in active/active mode (load-balanced) or used in active/passive mode.
• In active/active mode:
The WXC Series have the same priority configured and WCCP load-balances flows to both. In case of a
WXC Series failure, the WCCP protocol automatically detects it (after 15 seconds) and removes it from the list.
Note: WXC Series platforms have to be configured in a Cluster mode.
Branch-WXCs have a tunnel established to both WXC Series and load-balance traffic to both. In case of a
WXC Series failure, the branch-WXC automatically detects it (after 1 minute and 15 seconds by default) and
uses only the other WXC tunnel.
• In active/passive mode:
The WXC Series have different priorities configured and the Cisco router redirects the traffic to the first WCCP
Client (WXC) connected. In case of active WCCP Client (WXC) failure, the WCCP protocol automatically detects it
(after 15 seconds) and redirects the traffic to the WCCP Client (WXC) available with the highest priority.
Note: WXC Series platforms don’t have to be configured in a Cluster mode.
Branch-WXCs have a tunnel established on both WXC Series platforms but the active WXC Series is configured
as preferred decompressor. In case of a WXC Series failure, the branch-WXC automatically detects it (after 1
minute and 15 seconds by default) and uses the other WXC Series tunnel.
Different Load-Balancing Modes for WCCP
WCCP can share the traffic to multiple WCCP Clients (WXC). Up to four WXC Series platforms can be load-balanced
in the same WCCP service.
Two load-balancing modes are supported—Hash mode and Mask mode:
• WCCP Hash mode
This is the only WX Series mode supported up to WX Series Operating System release 5.6.
For each flow redirected by WCCP in Hash mode, the Cisco router does a hash on the source + destination IP@
and selects the WCCP Client based on the hash result. So the same flow will always be redirected to the same
WXC Series platform.
• WCCP Mask mode
This mode is supported on the WX Series from the WXOS release 5.7.
For each flow redirected by WCCP in Mask mode, Cisco does a hash on the source or the destination IP@ (by
default destination) and selects the WCCP Client based on the hash result. So the all the flows for the same
server IP@ will always be redirected to the same WXC Series platform.

APPLICATION NOTE - Juniper Networks WX Series Large Deployment with WCCP Off-Path Integration on Cisco
Depending on the Cisco model, both or only one WCCP mode is supported:
• Cisco 7200/7300/7400/7500/1800/2800/3800: WCCP Hash mode only
• Cisco 6500/7600: WCCP Hash and Mask mode
• Cisco 4500/4948: WCCP Mask mode only
• Cisco 3750: WCCP Mask mode only
WCCP Different Communication Modes
WCCP can communicate to WCCP Clients via two modes: L2 and GRE. The mode is negotiated between the
WCCP Server (Cisco) and WCCP Clients (WXC Series). The WXC Series does support both, but the Cisco routers
may support only one.
• L2 mode
This mode is the most efficient, as it doesn’t require encapsulation.
This is the mode used if supported by the Cisco WCCP Server and if there is no router between the WXC Series
and the Cisco WCCP Server.

• GRE mode
This mode encapsulates traffic in a GRE tunnel.
This is the mode used if the Cisco WCCP Server does not support L2 or if there is router between the
WXC Series and the Cisco WCCP Server.
Note: To avoid fragmentation due to the encapsulation, we recommend reducing the MSS to 1432 on the
WXC Series.

Depending on the Cisco model, both or only one mode is supported:
• Cisco 7200/7300/7400/7500/1800/2800/3800: GRE mode only
• Cisco 6500/7600: GRE and L2 mode supported
• Cisco 4500/4948: L2 mode only and no redirect lists (all traffic is redirected on the interface)
• Cisco 3750: L2 mode only and redirect lists with permit only
Note: The redirect list allows the Cisco administrator to specify what traffic will be redirected via WCCP to the WCCP
Clients. When the redirect list is not available, all traffic received on an interface will be redirected to WCCP Clients.

WCCP Unicast or Multicast Communication
WCCP supports unicast or multicast.
Multicast has to be used if multiple WCCP Servers (Cisco) will use the same WCCP Clients (WXC Series). Cisco
servers and the WXC Series support both modes. But some specific configuration has to be done for multicast mode
on the Cisco server.
• Unicast
Unicast can be used when one single WCCP Server (Cisco) uses one or multiple WCCP Clients (WXC Series)

Note: The configuration is based on a Cisco 6500. On other hardware the commands may differ slightly.
IOS Version
• Requires at least 12.2.33
WCCP Configuration
The WCCP multicast specific configuration is in italics.
• Define a loopback IP@ if none already exists
interface Loopback100
ip address 1.1.1.1 255.255.255.255
Note: Use “show ip interface brief” to see the Cisco’s IP@ list.
• ACL for redirection (what to redirect to the WXC Series)
!Branch1 subnet = 20.0.0.0/24
access-list 101 permit ip any 20.0.0.0 0.0.0.255
!Branch2 subnet = 30.0.0.0/24
access-list 102 permit ip any 30.0.0.0 0.0.0.255

APPLICATION NOTE - Juniper Networks WX Series Large Deployment with WCCP Off-Path Integration on Cisco
Note: To see what ACL matches, “show access-lists.”
• WCCP Service
! Service for Branch1 (in this case a multicast IP@ is used – even if unicast could be used
too)
ip wccp 60 group-address 239.1.1.100 redirect-list 101
ip wccp 70 group-address 239.1.1.100 redirect-list 101
! Service for Branch2 (in this case a multicast IP@ is used – even if unicast could be used too)
ip wccp 61 group-address 239.1.1.200 redirect-list 102
ip wccp 71 group-address 239.1.1.200 redirect-list 102
Note: Use “show ip wccp <service-id>” to see the WCCP statistics. Attention when the redirect-list is used in the
configuration, the wccp statistics doesn’t display the packets stats.
• Multicast specific configuration
!enable ip multicast routing
ip multicast-routing
!igmp snooping is not supported by WXC
no ip igmp snooping
• WCCP listen applied on the “WXC” interface (to detect WCCP Clients redirect - WXC Series)
! WXC supports the dense mode only
interface GigabitEthernet1/11
ip address 9.0.0.9 255.255.255.0
ip wccp 60 group-listen
ip wccp 70 group-listen
ip wccp 61 group-listen
ip wccp 71 group-listen
ip pim sparse-dense-mode
Note: Use “show ip wccp <service-id> view” to see the status of the WCCP Clients (WXC Series).
Note: Use “show ip wccp <service-id> detail” to see what communication mode is used (L2 or GRE).
• WCCP redirection applied on the “Local” interface (to redirect the traffic to the WXC Series)
interface GigabitEthernet1/12
ip address 8.0.0.9 255.255.255.0
ip wccp 60 redirect in
