This is a really confusing area!
OK...SRT (Source-Route Transparent) Bridging enables bridging between both a TR and Ethernet segment, but hosts will not communicate with other hosts on the other type of network. This means a TR host will not be able to communicate with an Ethernet host. All the bridging provides here is a transport to get from one network to another. Imagine this topology:
TR1---E---TR2
SRT will enable a host from TR1 to communicate with a host on TR2 through E. Even though the TR traffic will travers the Ethernet segment, the Ethernet hosts will not be able to read the data.
SR/TLB does indeed enable communications between a TR segment host and an Ethernet segment host. There are some things lost in the translation (isn't there always?) so it's not a great way to go. I think I would prefer routing in this case to bridging sonce the layer 3 stuff is independent of the layer 2 incompatibilities.
Here is a great link to help explain it all (watch the wrap!):

Hope this helps!

Subject: Question about SRT and SR/TLB
I know that with SR/TLB, the bridge add and remove RIF according the
direction of the frame. My question is, with SRT, does the bridge add
and remove RIF? Thanks.
I am reading two books here. One book says yes, the other book says
no. So I am confused.
