3570 WAAS Configuration

Hi

Since WCCP has been enabled on the 3750's there has never been the WCCP option to "ip wccp redirect exclude in" from the WAAS unit to stop Loops.

Is there any way round this or is the only option to configure PBR on the 3750.

Thanks

Hi,

The 3750 doesn't support redirect-out, which is where you would want to use the "redirect exclude in" statements. 3750s only support redirect-in (L2-redirect, L2-return, mask-assign, redirect-in are the rules for that platform).

Basically if you are doing redirection on multiple 3750s (not stacked), then they will have to share a L2 subnet that isn't being redirected for the WAEs to return egress traffic to.

Hope that helps,

Hi Dan,

So as I understand it, provide I put the redirects "in" on the interfaces I want and not the WAAS ones. I should be ok.

Ian,

You are correct. You would put 61 "in" on one direction (LAN for example) and 62 "in" on the other (WAN) and no redirection on the WAAS interface. You don't want to re-intercept egress traffic from the WAE as it would get caught in a redirection loop.

Also, be aware you need to enable a routing SDM Template to enable WCCP on the 3750.

Hope that helps,
