Read the damn question.  The subject line clearly says GRE tunnel on GSR 
- if you're not labbing up the same scenario, don't contribute FUD.

For the unaware, GSRs need a dedicated OC48 Engine2 or Engine3 card as a 
tunnel server card.  The card CAN'T be used for an actual live OC48; it 
has to be specially configured as a TSC.  GSRs don't run IOS 12.3, and 
even if you were labbing up a GSR on an appropriate IOS and using a GRP 
in slot0 and its companion E0/0, it wouldn't have full reachability.
