Further, uRPF is frequently a very inefficient means of implementing BCP
38. Consider that you're going to either compare the source address
against a table of 200,000 routes or against a handful of prefixes that
you've statically configured in an ACL.
Yes, I realize that the latter approach is more of a managerial hassle,
but for those of you who feel that your silicon is running a tad too
warm, you may wish to consider this as a possible performance
improvement technique. YMMV.
Your former router vendor,
