Re: MA on spoke router !! Rp on another spoke !! sender/receier

thanks Anthony,

ip pim nbma mode command should technically inject other spokes in OIL list
.

i have seen brain tricking a solution as follows

on spoke / hub configure static rp with access list that permits 224.0.1.39
and 224.0.1.40
so that hub can treat these two groups as sparse . so hub should forward
traffic out to every spoke
as present in OIL

theoretically logical when tested on gns3 , no success .
