WAAS VLAN - not all traffic is being forwarded to WAE

Hi, I've configured a WAAS topology based on this Cisco document

(http://www.cisco.com/application/pdf/en/us/guest/netsol/ns377/c649/ccmigration_09186a008081c7da.pdf)

where the WAE's are in their own VLAN and there is a trunk between the 2 edge routers and 2 6509 switches (the WAE's connect to this switch). Both the "data" vlan and the WAAS vlan is participating in EIGRP which means that traffic is being routed over both sub-interfaces. The problems is that one of the sub-interfaces has the "ip wccp redirect exclude in" command configured so only half the traffic will be passed to the WAE's. Has anyone come across this before? Should I be removing the WAAS vlan from EIGRP and using the second interface on the WAE for management in a seperate subnet?

Re: WAAS VLAN - not all traffic is being forwarded to WAE

BRADLEY,

In this case you should make the data VLAN passive (from an EIGRP perspective) and use the WAE VLAN as a transit between the two routers. You don't want traffic coming in from the WAE VLAN to get re-intercepted.
