Chapter 1 Configuring Traffic Interception
Using Policy-Based Routing Interception
Figure 1-5 Example of Using PBR or WCCP Version 2 for Transparent Redirection of All TCP Traffic to WAEs
Table 1-3 provides a summary of the router interfaces that you must configure to use PBR or WCCP
Version 2 to transparently redirect traffic to a WAE.
Note In Figure 1-5, redundancy (for example, redundant routers, switches, WAEs, WAAS Central Managers,
and routers) is not depicted.
The example in the “Configuring Policy-Based Routing” section on page 1-36 shows how to configure
PBR as the traffic redirection method in a WAAS network that has one WAE in a branch office and one
WAE in the data center (as shown in Figure 1-5).

Edge-Router1
A Edge LAN interface (ingress interface) that performs redirection on outbound traffic.
B Tertiary interface (separate physical interface) or a subinterface off of the LAN port on Edge-Router1. Used to
attach Edge-WAE1 to Edge-Router1 in the branch office.
C Edge WAN interface (egress interface) on Edge-Router1 that performs redirection on inbound traffic.
Core-Router1
D Core LAN interface (ingress interface) that performs redirection on outbound traffic.
E Tertiary interface or subinterface off of the LAN port on Core-Router1. Used to attach Core-WAE1 to
Core-Router1 in the data center.
F Core WAN interface (egress interface) on Core-Router1 that performs redirection on inbound traffic.
