Well is it just a CEF problem or also as-path/regexp problem?
CEF fails in various definable (if not fixable) ways, I've never seen
a problem with as-path stuff. If CEF is involved, that I'd wonder if
it's as-paths getting corrupted or just bad routes that are getting
clear as part of the workaround...
We've been thru the CEF nightmares but haven't seen as-path problems.
