Subject: SPT-bit during Register process

Hello,

I have a remark concerning the new draft-ietf-pim-sm-v2-new-00.ps about the
SPT-bit during the Register process. This bit must be set to "1" when the RP
receives the 1st data packet on the SPT tree. The Update_SPTbit procedure (see
page 15) contains a line that should carry this action ( RPF_interface(S) !=
RPF_interface(RP)). But the definition of RPF_interface(RP) at the RP is "the
virtual interface on which register packets are received" (see page 13): so we
have RPF_interface(S)= RPF_interface(RP) and SPT-bit will not be set to "1".
