Figure 4-6 WCCP Redirection Using GRE Forwarding

Figure 4-7 WCCP Redirection Using L2 Forwarding

One of the beneﬁts of L2 forwarding is that it allows for the WCCPv2 redirection to occur

in hardware on Cisco Catalyst Series switches. In fact, on the Catalyst 3560/3750 and 4500/

4948 series switches, the only forwarding method supported by WCCPv2 is L2 forwarding.

Additional information about the conﬁguration requirements for deploying WCCPv2 on

Cisco Catalyst switches is provided in the “WCCP Conﬁguration” section.
