Ashutosh,
It is not a requirement to use the local SLD in SolMan. In fact, if you have another SLD available, as Bala does, I would recommend not using SolMan's SLD, for a variety of reasons. Chances are his PI-based SLD is on a higher NetWeaver version, and so will have greater functionality. So, no bridge setup is required. There are numerous blogs and documents on SCN with this recommendation.
Cheers,
Matt
