I'm studying multicast. While I was reading a book, I saw this: "A multicast router can have more than one interface in the outgoing interface list, but it can have only one interface in the incoming interface list.".
The excerpt above is talking about the "show ip mroute" command.
The question is: what if I have to routes to the same source of multicast traffic - let's say, through two different interfaces using the same cost? I'll have two routes in my unicast routing table, right?
How can PIM handle this? Will it choose one of them and discard the other one?
These doubts are obvious to come when you start reading multicast. Keep going ahead and you will come to know across the way PIM take different decisions.
For now coming to your doubt you can read these 2 links and I am sure you will be clear about many stuff
Read section 2.9 from this link
Please come back if you have any doubts.
