Connecting a Station to a Server in Source Route Bridging

Introduction	The following is an example of the process involved in establishing a connection
	between a station on one Token Ring LAN with a server on a remote Token Ring
	LAN for a Source Route Bridging operation.
Procedure
	These steps describes the process of how a a station to server connection is set up:
	1) The PC station (source) on LAN AAA requests a session to a server (destination)
	located on remote LAN CCC (Figure 21).

2)The PC assumes the server is on the local LAN, and the PC sends an LLC frame (typically an LLC1 TEST frame) around its local LAN AAA looking for a response from the server. The TEST frame has a destination MAC Address equal to the server’s MAC Address. Since the server is not on the local ring, no station responds to the server’s destination MAC Address (Figure 22). This TEST frame does not have the Routing Information Indicator bit (RII) set (the high order bit in the Source MAC Address) and as a result, it does not build a Routing Information Field (RIF) to trace the path to the destination.
