As you probably know, the tools page for an internet-draft, like
http://tools.ietf.org/html/draft-ietf-ipfix-protocol-rfc5101bis-01
includes links for jumping from one version to the next, and for showing
the differences between the version you're viewing and the previous
version.  When one document succeeds another, such as a WG document
replacing an individual one or, in this case, the individual document
being the start of a revision of RFC5101, those links inlcude the
ability to jump from one document to the next, and to compare the first
version of one document with the last version of the document before it.

So, if you go to the page for draft-claise-ipfix-protocol-rfc5101bis-00
and click the "Diff1" link, you'll see differences in that document
since RFC5101.

As far as I know, there is no "friendly" way to click on something and
see differences between two documents that are not immediately adjacent
versions.  However, you can fairly easily edit the URL to get what you
want.  Simply bring up the diff page for the later document, and add
"&url1=XXX" to the end of the URL, where XXX is the document you want to
compare against.  Acceptable forms include draft-foo-bar-00 and rfcXXXX.

So, to see the differences between the most recent rfc5101bis and the
original rfc5101, try this:


http://tools.ietf.org/rfcdiff?url2=draft-ietf-ipfix-protocol-rfc5101bis-01.txt&url1=rfc5101
