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 RFC 1483 PDUs only.
