OK - so logically is it like this from my config below:
Ring 10 ----- Bridge 2 ------ Ring 1000 -------- *Bridge 2 ------- Ring 2000
(=TB 1)
The *Bridge 2 is specified by third number in source-bridge 1000 2000 2 1??
Based on your reply, doesn't this break the rule of identical bridge numbers
(probably, but this is a purely logical connection with no hosts on the
intermediate ring so does it really matter).
So I could also have the following with:
source-bridge transparent 1000 2000 *4 1
int to0
source-bridge 10 **2 1000
Ring 10 ----- **Bridge 2 ----- Ring 1000 ----- *Bridge 4 ----- Ring 2000
(=TB1)
Does this make logical sense??

It does not necessarily mean the bridge specified in the source bridge
command. It is defining a bridge number of a bridge that links the
logical source route domain with the logical transparent domain. It
must be a valid source route bridge number.

different bridge numbers than those under the interface will work as long
as it is a valid source route bridge number.

in general the bridge numbers do not have to be unique. There is exactly
one circumstance where the bridge numbers must be unique and that is the
situation where two rings are connected by two bridges, in which case the
two bridge numbers must be unique.
