WAAS using WCCP from 2 6509's?

Unanswered Question
Oct 21st, 2008

I am preparing to install a WAE in the datacenter using WCCP for redirection of traffic to 1 of my networks on a point-to-multipoint frame relay network. Where things get foggy is the WCCP server install on my "router" which is actually 2 6509's which are used to route different vlans for both redundancy and load-balancing in the Datacenter. Is it possible/advisable to set both up with WCCP to redirect to the WAE? Could this cause any unforeseen issues?

I'm also wondering about traffic that is destined for other networks on that point-to-multipoint frame relay connection that my remote site is on which will have the other WAE. Will it be easy to specify which traffic to redirect to the WAE (that which is destined for that one remote site) or will this also cause issues?

Thanks in advance!

I have this problem too.

Karen,

With WCCP, you can have multiple WAEs (theoretically up to 32) and multiple routers (again up to 32) in the service group. So in your case, both routers can be registered to the same WAE(s). You can limit traffic via a redirect-list, which is an ACL (only accept traffic to/from your remote site).

WCCP is configured on the interfaces for the service groups you are interested in. For WAAS, you use services 61 and 62 in opposite directions to perform load balancing appropriately.

A hint on your wccp on the 6500. Always configure redirect-in on the interfaces, L2-redirect and mask-assign to keep the traffic processed in hardware.

Here is a link on configuring WCCP for WAAS (which I assume you are deploying).

Hope that helps,

Dan
