Option Name:wccp2_forwarding_method
Default Value:wccp2_forwarding_method gre
Suggested Config:

	WCCP2 allows the setting of forwarding methods between the
	router/switch and the cache.  Valid values are as follows:

	gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
	l2  - L2 redirect (forward the packet using Layer 2/MAC rewriting)

	Currently (as of IOS 12.4) cisco routers only support GRE.
	Cisco switches only support the L2 redirect assignment method.
