The easy way to remember is just follow the first two keywords
Source-bridge transparent 100 1000 4 3
SB TB SB(Vir) TB(vir) SB(br#) TB(BG#)
Also remember, are you configuring DLSW or just normal bridgeing ?

Be careful with the term dummy bridge. This is actually the bridge number
under the token interface. If any bridge is the dummy bridge it would be the
pseudo bridge.
When in doubt remember the command is ordered in pairs:
Source-bridge transparent 100 1000 4 3
The first two numbers are ring numbers - the first for the token side if you
like (the virtual ring) and the second is the ether ring (the pseudo ring).
The second pair of numbers relate to the bridges, the first the token bridge
and the second the ether bridge. This makes it easier to read the command
and know what number relate to what,

If doing true SRB (Source Route Bridging) and connected to
the 3920,
remember to turn on SRB on the routers, otherwise no go:
Interface TokenRing 0
multiring all (or multiring ip, or multiring ipx, you get
the idea)
For transparent (SRT) you can just plain old SRB and
SPANNING explorers
under the interface. For purely SNA traffic, I do not
believe you need
spanning explorers. But, when in doubt, ask the proctor what
is the best
course of action is my opinion.
For translational you must do the global command:
source-bridge transparent 20 3 4 1
where
10 is the source-bridge ring-group
3 is a pseudo ring
4 is a dummy bridge to the Transparent Bridge
1 is the actual transparent bridge
All this for DLSw, yes :-)
One more thing. If you are doing RIF passthrough, make sure
your VIRTUAL
RING is the same on both ends of the peering relationship.
Or it will
not work (I assume it behaves just like RSRB)
