Sorry Guys I forgot to post the configs of R1 which is very important for
this set up. ( Thanks for reminding me Annu)
hostname R1
!
enable password cisco
!
ip subnet-zero
no ip domain-lookup
isdn switch-type basic-ni
!
interface Serial0
no ip directed-broadcast
no ip mroute-cache
no fair-queue
clockrate 72000
!
interface Serial1
no ip directed-broadcast
ip ospf cost 1
!
interface TokenRing0
ip address 10.10.10.5 255.255.255.0
no ip directed-broadcast
ring-speed 16
multiring ip
Very important command on R1 for this set up to work.

R1#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 10.10.10.4 0 0007.787c.8598 SNAP TokenRing0
Internet 10.10.10.5 - 0007.ef8a.5bde SNAP TokenRing0
R1#ping 10.10.10.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.10.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/34/36 ms
Again SR/TLB works.
It was ot working in the beginning and suddenly it started working. Again be
careful about putting any layer three address on the bridge ( even though u
have turned off IP routing).
SR/TLB STRANGE SET UP- but works
Set is as follows
R1
------T0-------------R2-------------so------------R3------------------Eo----
--------------R4
R1 and R4 end hosts.
R2 is doing the Source route Translational bridging.
R3 is doing Transparent bridging.
Criteria : SR / TLB.
