Section 4.5.4 says:
The compound Join/Prune message contains a Prune(S,G,rpt). The (S,G,rpt) downstream state machine on interface I transitions back to the Prune state. The Expiry Timer (ET) is restarted, set to maximum of its current value and the HoldTime from the triggering Join/Prune message.
It should say:
A compound Join/Prune message containing a Prune(S,G<rpt) is received on interface I with its Upstream Neighbor Address set to the router’s primary IP address on I. The (S,G,rpt) downstream state machine on interface I transitions back to the Prune state. The Expiry Timer (ET) is restarted, set to maximum of its current value and the HoldTime from the triggering Join/Prune message.
Notes:
This section does not consider “Upstream Neighbor Address” as does “Receive Prune(S,G,rpt)” in “Transitions from Prune State” on page 60 or “Receive Prune(S,G,rpt)” in “Transitions from Prune-Pending State” on page 59. Is that information not important in this state transition?
