WCCP Creates additional tunnel interfaces

Hi,

I'm having 2911 routers with Cisco WAAS module installed. While configuring the WCCP on the 2911 router, I see additional interface tunnels gets automatically created once I issue ip wccp 61 and ip wccp 62.

It gives these tunnel ip address from 172.16.0.0 block.

for that these tunnels are required ??

Re: WCCP Creates additional tunnel interfaces

The tunnels are created automatically to process outgoing GRE encapsulated traffic for WCCP.  They appear when a WCCP client  connects and requests GRE redirection.  There is one tunnel created per service group that is using GRE redirection, plus one additional tunnel to provide an IP  address to allow the other tunnel group interfaces to be unnumbered but still enabled for IPv4.

Regards,

Zach
