The end station should be assigned to a multicast group which it is intersted in. To make it clear, the end station application should be configured with one multicast IP address which it would like to receive data from. Imagine the end station is your TV at home and the sources are all the channels out there.
The RP doesn't. The RP joins the SP-Tree to each source router and forwards the traffic from both sources. The DR (the router directly connected to the receivers) initiates the SP-Tree join to the closest source, and then prunes itself from the RP-based shared tree.
Independent of whether the DR joins the shortest path tree towards the source, the IGMPv2 can only request a multicast group, it can't specify the source, so if using IGMPv2, and the PC requests group 188.8.131.52, and there are 20 sources sending to this group, the PC will receive traffic from all 20 sources. If you want the PC to select a group and a source you need IGMPv3.
This document gives several answers on frequently asked questions for PFRv3 channel state behavior.
Q1: What are all the channel operational states from a BR (border role) perspective and what are the rules/conditions to be in each st...
The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
I couldn't connect to the hos...
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
