<p class="MsoNormal">Agree with Adam’s statement, use uRPF on
edge DIA customers. Using it elsewhere on the network
eventually is going to cause some issue and its usefulness
today is almost nil. That being said we still see large
providers who have it turned on for peering/transit interfaces
either out of legacy configuration or other reasons. The vast
majority do not use it for those interface roles. <o:p></o:p></p>

If you don't plan to run a full BGP table on a device, don't enable
uRPF, even loose-mode.<br>
