On a router, you can always use HEX notation in order to make your life
easier:
r2(config-if)#source-bridge 0x119 1 0x23
r2(config-if)#^Z
r2#sh run in to 0
Building configuration...
Current configuration:
!
interface TokenRing0
no ip address
no ip directed-broadcast
shutdown
source-bridge 281 1 35
end
