The following shows an example of rate limiting the LWAPP control traffic from the WAN site to 
minimize the impact of the CS6-marked control traffic on routing traffic. Note that the rate limit 
configuration does not drop non-conforming traffic, but simply reclassifies that traffic.

Note that this is an example, and not a recommendation. Under normal circumstances, and following the 
design guidelines for deploying APs over a WAN connection, it is unlikely that LWAPP control traffic 
would impact the WAN routing protocol connection.
