WCCP when using an HSRP VIP address not working ?

Hi

I have been testing a WCCP setup with a Debian 6.0 server running squid and a 6500 with SUP720 running  12.2(18)SXF17a. So far so good and it's working fine.

At the moment the squid config is setup to use the SVI IP of the VLAN that the squid servers live in. But since we have two 6500 chassis and the squid servers are connected to both i setup HSRP for the VLAN and tried pointing the squid config to the HSRP VIP. Sadly this doesn't work and i was wondering if it should/am i doing something wrong?

When i use the HRSP VIP i only see these log entries

Apr 14 10:09:23 cest: WCCP-PKT:S00: Sending I_See_You packet to 10.64.9.116 w/ rcv_id 0000D105
Apr 14 10:09:33 cest: WCCP-EVNT:S00: Here_I_Am packet from 10.64.9.116 w/bad rcv_id 00000000
Apr 14 10:09:33 cest: WCCP-PKT:S00: Sending I_See_You packet to 10.64.9.116 w/ rcv_id 0000D106
Apr 14 10:09:43 cest: WCCP-EVNT:S00: Here_I_Am packet from 10.64.9.116 w/bad rcv_id 00000000


but when i use the SVI IP, the squid web cache correctly registers with the 6500 i get this in the log:

Apr 14 10:12:25 cest: WCCP-PKT:S00: Sending I_See_You packet to 10.64.9.116 w/ rcv_id 0000D114

Apr 14 10:13:12 cest: WCCP-PKT:S00: Sending I_See_You packet to 10.64.9.116 w/ rcv_id 0000D117

I don't know but maybe using the HRSP VIP stops the GRE adjacency forming so it brakes ?

Does anyone know if this is possible?

thanks
Scott

That actually needs to be registered with the SVI IP Address not the HSRP address.

Configure squid to register to both the core switches.
