Hi all,
 I have a question regarding DVMRP v3 as explained in draft-ietf-idmr-dvmrp-v3(September 
1999).

 Prune messages are sent to prune the multicast tree and graft messages to add the 
branches.I donot understand the need for prune timers. Why do we need to maintain prune 
timers and join back the branches which have already been pruned after the timer expires, 
There is a specific graft messages to join back the branches. 

Regards,
Vijay
