WAAS and Routers running HSRP

I am just in the process of deploying WAAS across our network. I have found that when the WAN router that is running WCCP has been configured for HSRP and is the active router i see the following

If I try and telnet to the HSRP standby address it does not connect and I get the following error message :

Jan 30 18:04:36.930 AU-Summ: %IP-3-LOOPPAK: Looping packet detected and dropped

-

in=GigabitEthernet0/0.9, nexthop=172.16.9.251, out=GigabitEthernet0/0.9

options=none

-Process= "IP Input", ipl= 0, pid= 82

-Traceback= 0x611B33C0 0x616A0FD4 0x616A11E0 0x616A1C14 0x616A1FE4 0x6168D09C 0x

6168E880 0x6168C384 0x6168C648 0x6168C704 0x6168C8A8

f I telnet to the actual router address then ok.

is this a Bug?

Re: WAAS and Routers running HSRP

just seen other question about HSRP and tried the

"egress-method negotiated-return intercept-method wccp' command but made no difference

see router interface configuration below

Note if no HSRP then no problem

Re: WAAS and Routers running HSRP

Richard,

The problem you are reporting is CSCsg30875. You can work around this issue by defing a redirect-list that denies traffic destined to the IP address(es) of the router itself.
