No it was never removed from 12.2(25)S. We did have some problems
with the standby booting if you used the encryption image. I'd
have to dig up that bug but if you are using the -pv- feature
set that problem shouldn't exist.

Well that is what I'm telling the customers I work with a lot.
Wait for the SB release to come out which is based on post
12.2(25)S code that has the performance issues resolved and
also has better feature parity (ie: MLPPP w/ MPLS functionality).

If you want the best HA then you will want the SB based code that
can give you MPLS NSF.

It's technically in 12.2(25)S but I haven't worked with a customer
that has tried it yet.
