Source Route Bridging (2)
Source Route Bridge assumes that the complete source-to-destination route is placed in all inter-LAN frames sent by the source
Source Route Bridge stores and forwards frames
Frames: test frame and explorer frame used to discover source-to-destination path between host X and host Y
After a route is defined and selected, it is inserted into a routing information field (RIF) in frames
RIF consists of Routing Control Field and Routing Descriptor (up to 13 bridges / hops allowed)
