I hope the mentioned below answer your Q
Does the Gigabit Switch Router (GSR) support bridging?
  A.  No.  The GSR runs Cisco IOS. Software Releases 12.0S and 11.2GS, which
are designed to provide robust IP routing and enhanced IP services for the
Internet Service Provider (ISP) community.  They do not provide support for
full bridging protocols such as transparent bridging or source route
bridging, nor do they support integrated routing and bridging (IRB).
However, you can use bridged-style permanent virtual circuits (BPVCs) to
allow ATM line cards to connect to a Catalyst switch or to another remote
device that supports bridged-format request for comments
