Updating Main Trunk is Updating Branch

[Garg, Sukh]

Hi,
pls help me out.

File: browse.jsp       Status: Up-to-date

   Working revision:    1.1.1.1
   Repository revision: 1.1.1.1 /cvs/NewJSP/src/products/browse.jsp,v
   Sticky Tag:          (none)
   Sticky Date:         (none)
   Sticky Options:      -kb

   Existing Tags:
        NewJSP-2001_10_01-Branch1   (branch: 1.1.1.1.2)
        NewJSP-2001_10_01-Tag1     (revision: 1.1.1.1)
        NewJSP_Rel_1               (revision: 1.1.1.1)
        init                            (revision: 1.1.1.1)
        start                           (branch: 1.1.1)

Above output is a result of "cvs status -v" command for my prj.

1. everything whatever i did, i did it from client WinNT.(CVS server is
Unix)
-Tagging is done using rtag i.e "cvs rtag tagName moduleName"
-Branching is done using rtag i.e "cvs rtag -b -r tagName branchName
moduleName"
-module was tagged before branching.

Now questions :
1. Is my approach for Tagging & branching OK???
2. If it's Ok then why changes made on Main Trunk are visible on Branch as
well.Though i never merged main trunk with branch.

So pls suggest me what's wrong.

thanx
sukh
