Source-routing is described in Annex C of
IEEE 802.1D (ISO/IEC 15802-3). "Media Access Control (MAC) Bridges." 1998.
Some of the issues that arise in translating between Ethernet frames that contain a type field and 802.3, 802.5, and FDDI frames are discussed in
ANSI/IEEE Standard 802.1H (ISO/IEC Technical Report 11802-5). "Media Access Control (MAC) Bridging of Ethernet V2.0 in Local Area Networks." 1997.
VLANs and E-RIFs are described in
IEEE 802.1Q. "Virtual Bridged Local Area Networks." 1998.
Insight into source-routing bridge configuration parameters can be gained by examining the IETF document:
RFC 1525. "Definitions of Managed Objects for Source Routing Bridges." E. Decker, K. McCloghrie, P. Langille, and A. Rijsinghani. 1993. ...
