Hi,
The source-bridge commands will have no effect...
The issue is more likely related to the way the Cisco router is
translating the frame to Ethernet and vice versa...as the other guy
said, you'll need the global command on R2:
bridge 1 bitswap-layer3-addresses
This command bitswaps MAC addresses contained in ARP packets (the router
bitswaps only the Layer 2 fields by default). So in combinations with
adding the to0 interface to bridge-group 1, should work...
See

Ok, I think I am getting warmer. Would I also remove the two global
commands
that say source-bridge ring-group and source-bridge transparent plus the
source-bridge interface command? In an earlier attmept I had both
interfaces in bridge-group 1 but they still wouldn't pass info.

Sorry, I misread your config, I thought R2 was performing SRB...
Because R2 is not performing SRB, it sends frames without a RIF.
Therefore, you must enable SRT on R1 to make this work. This is done
by:
R1:
int to0
bridge-group 1

In my home lab, I setup R1 as a translational bridge and I put R2 on the
token segment and put R3 on the Ethernet segment but they don't talk.
Here is the config:
R1
source-bridge ring-group 10
source-bridge transparent 10 3 1 1
!
int e0
no ip add
bridge-group 1
!
int to0
no ip add
source-bridge 1 1 10
ring 16
!
bridge 1 protocol ieee
end
R2
int to0
ip add 10.1.1.1 255.255.255.0
ring 16
!
end
R3
int e0
ip add 10.1.1.2 255.255.255.0
!
end
