Configuring the Ethernet or Token Ring Port 5 - 5
Setting Up the Infrastructure Topology (Tring, Rring, Bridge) Token Ring Only
When you use Token Ring Bridges to connect two or more source routed
Token Rings together, the Token Ring Bridges create a virtual Token
Ring out of the infrastructure. This allows nodes on the infrastructure to
have source routes of their own and allows for easier routing of the
packets through the Token Ring Bridges.
In the example, the “rring” parameter in all units would be assigned to
300. On the root unit (Bridge 1) the Bridge would be set to number to 1
and the “tring” number to 100. For repeater A (Bridge 2) set the Bridge
number to 2 and the “tring” number to 200. For repeater B (Bridge 3) set
the Bridge number to 3 and the “tring” number to 201. An example
source route from Workstation A to the file server, in ring and Bridge
number pairs, would be 200-2 300-1 100.
All ring and Bridge numbers must be entered and will be displayed in
hexadecimal.
