How do routers elect "Designated Web-cache" in WCCP environment?
Environment: Cisco Web Security Appliance (WSA) used with WCCP redirection
Election of the designated web-cache will take place once a Service Group membership has established, during initial handshake or following a change. The designated web-cache must be receiving a WCCP2_I_SEE_YOU message from every router in the Service Group.
Election of the designated web-cache is not part of the WCCP protocol.
