Please Check, I think the correct option is to configure interface bandwidth on all routers, I tested in LAB, 
and traffic did flow through CapeTown --> Tokyo --> Dubai router after following

! Configuration for Cape Town
interface E 0/0
bandwidth 5000
interface E 0/1
bandwidth 10000

! Configuration for Dubai
interface E 0/0
bandwidth 50000
interface E 0/1
bandwidth 5000

! Configuration for Tokyo
interface E 0/0
bandwidth 50000
interface E 0/1
bandwidth 10000
