CEF and MPLS workflow

[waimen]

Hi all,

Is there any links in the web site explain the work flow of cef in detail (but easy to understand)? And why we must enable cef first when use MPLS? Thank You!

MPLS is using CEF switching to make label switching and all the necessary rewrites including the label rewrite.
