I have a switch (WS-C3560G-24TS-E) that supports WCCP for the web proxy zone.
Based on the diagram, if the remote users come in from the IP VPN C+, the switch will forward all web requests to the BlueCoat ProxySG via WCCP, then ProxySG will send the web requests to firewall to internet as part of the default route.
If BlueCoat ProxySG fails, can the Cisco switch WCCP configuration detect a failure and send the web requests to the firewall as part of the default route?
yes because WCCP include the exchange of hello messages between the router/switch and the web cache.
If the web cache fails the router detects the missing WCCP messages.
WCCP Message Exchange
This sequence of events describes the WCCP message exchange:
1. The application engines send their IP addresses to the WCCP-enabled switch by using WCCP, signaling their presence through a Here I am message. The switch and application engines communicate to each other through a control channel based on UDP port 2048.
Thanks for the info! Based on the diagram, can I remove the WCCP-enabled switch, and connect the MegaPop router can connect straight to the ProxySG and Firewall. Though this would require me to get additional FE modules to connect ProxySG and FW.
