what is difference between topmost exp and exp  on mplsqos ?

 when i want change exp on P1 to P2 (from 5 to 3 ) ,i should use what
command ?

R3(config-pmap-c)#set mpls experimental ?
  <0-7>       Experimental value
  imposition  Set Experimental value at tag imposition
  topmost     Set Experimental value on topmost label


icmp packets from ce1 to ce2 on pe1 marked by ef . packets capture between
PE1 ,P1 that have exp 5 .
I want change exp to 3 from P1 to P2 .then i config policy-map on P1 and
set mpls experimental topmost 3 on it and config on ingress interface.
When capture traffic ,i see pachets have exp 5 .
please have a sulotion for this problem .
