Explcit GUP

HI ,

What exactly is explicit GUP.

Does GUPs across sites ?

If we have have a muliplt GUP provider list , does that mean it will work across sites.

ALso if we combine multiple GUP provider and explict GUP provider , it would mean one single policy will take care of all the groups , even the roaming clients .( correct me if i am wrong ).

This can be achived by

1) cretae a multiple gup provider list with all the GUPs listed

2) map each subnet/location existing to a GUP provider in the explicit GUP provider column .

help would be appreciated.
