Hi,
SRT is used when you have to bridge devices, some of which
use RIFs and some that don't.
I wouldn't used it for Token <> Ethernet - use Translational.
Example
A router with two token rings and two ethernets.
Bridging process checks for RIF, if present use SRB if missing
use TB
MTUs must be the same
I think thats correct..
Cheers
Mark
