  Nethan,
  sorry to say, but a detailed step-by-step you don't will have.
  Which your real difficulties in deploy the CGN solution on GSR?
  If you aren't confortable on IOS-XR,You can convert the CRS solution
  provided by Cisco (IOS-XR based) to IOS configs and then deploy on
  GSR.
  Please, give us more details about your doubts..

  Cheers,

     Hi Experts,

     Is there is anyone who has tried CGN ( Carrier Grade Natting) ?
     All the Cisco configurations docs are for cisco CRS. But I'm
     searching to do it on 12000 GSR with PRP3 installed with Booster
     card.
     I'm searching for a good document for step by step process for
     the configurations and want to learn how it work.

     Best Regards,
