Re: [squid-users] squid 2.6STABLE9 WCCPv2 CISCO 2600 w/bad recv_id 00000000

Hi,

here is more output of the router confirming that the communication is kind of
working:

router1#debug ip wccp packets
WCCP packet info debugging is on
router1#
1d02h: WCCP-PKT:D97: Received valid Here_I_Am packet from 192.168.3.20 w/rcv_id 000002F4

1d02h: WCCP-PKT:D97: Received valid Here_I_Am packet from 192.168.3.20 w/rcv_id 000002F8
...

however, no output on cache.log, running squid with parameters -NDX -d9
