The task ask for WCCP that support more protocol beyond http so it means we should use version 2.
WCCP Version2 should have service-groupID configured before cache engine register the service-group:
ip wccp <service groupID> group-address <multicast> redirect-list <acl>
But the SG doesn't address that, instead still using regular version 1 configuration.
ip wccp web-cache
ip wccp web-cache redirect-list <acl>
Any comment from INE ?
