With regards to SSO-NSF and HSRP I've read documents on ciscos site that
conflict when discussing the use of NSF.
One indicates do not use HSRP and NSF together on the same box.

That is from 2006 (see below)

That 2nd link is just referring to Enhanced Object Tracking & HSRP.
I've read in another article (sorry, don't have the URL handy at the
moment but I think I saw in a PDF from cisco.com) that either implied
the use of NSF and HSRP together was OK thru config examples or
something or else explicitly stated the use of the to together is OK.
Can anyone comment on this conflict? Also does this conflict with NSF
also apply to GLBP which can be configured in a way to behave similar to
that of HSRP? The second link above makes comment of GLBP but the first
one does not. Is GLBP newer than the first article?
We use NSF and HSRP just fine, and have done since 12.2(18)SXF. Although
it was "not supported" in that release, it seemed to cause no problems -
either the standby took over, or the master managed to "beat" the missed
HSRP packets.
12.2(33)SXI adds support for SSO HSRP - see the release notes, and docs
here:
