Hi GS,

R5 join group 239.1.1.1 , and I ping it from R1 :
I configure all of enable multicast routers with "ip pim spt-threshold
infinity"

output of sh ip mroute of R5:

Does flag for (*, 239.1.1.1) -->SJCL correct???? solution stated that it
should not contain "J".
I don't know what cause this issue ,actually if R5 join any other group this
command work for it and it does not join SPT . but it does not work for
239.1.1.1 . I don't know what prevent executing "ip pim spt-threshold
infinity" for 239.1.1.1 group.
