WAAS 61 /62 Service..

[wrobbin]

I know Cisco Reccomends  ip wccp 62 redirect in on WAN interfaces and ip wccp 61 redirect in on LAN interfaces but does it really matter? Reason i ask i came into to an organization where it is  flip flopped...Seems to me it should be ok just as long as i do it the same across the board?

It is actually common to see 61 and 62 flipped when you're at a DC site.  This is typically done to distribute the load more evenly between multiple WAEs in the WCCP farm since based on the traffic pattern at this site there are more unique source IPs coming in than there are unique destinations.  61 hashes based on source IP and 62 hashes based on the destination IP.  If there is only 1 WAE in the WCCP farm then it doesn't really matter since all traffic is going to be redirected to only 1 WAE.
