  1. Heya,

    is it possible to use a HSRP pair instead of a single Cisco device? I guess it’s not possible to terminate a GRE on a HSRP VIP …


  2. Hi Andrew,

    WCCP can be a pain to make it work. My plan was to spend 1-2 hours of configuring it so I could write a blogpost on it but it took me a full day to get it to work :wink:

    If you doubt your router config…please boot up a router in GNS3 with just the minimum configuration required for WCCP, just pick the config that I used. IOS 15 also gives you more show commands for WCCP than 12.4. Did you also check iptables? Making sure it’s not blocking any traffic?


  3. Hi Rene

    We have issues setting this WCCP up with vlan’s on a CISCO887VA with Adv IP services IOS and a GNU/Linux machine with squid, is our config correct when applying the ip wccp cmd’s to the vlan ?

    interface Vlan10
     description finance
     ip address
     ip nat inside
     ip virtual-reassembly in
    interface Vlan20
     description warehouse
     ip address
     ip wccp web-cache redirect in
     ip nat inside
     no ip virtual-reassembly in
    interface Vlan30

  5. Hi Tim,

    WCCP is pretty confusing, this tutorial took me about 6 hours from start to finish. I had a lot of troubleshooting to do before this worked…

    Your config looks OK and you can see the router is redirecting traffic:

    Redirected Packets:
    Process: 0
    CEF: 929

    You don’t have to worry about tunnel source and ip unnumbered for the WCCP configuration. When you configure a “normal” GRE tunnel between two routers you have to specify the source + destination of the tunnel yourself, now we don’t have to because WCCP does this for us.
