Hello Everyone,
I have just enabled multicast on my routers for our voice paging system and everything seems to work fine. However, I'm afraid I maybe missing some commands I could use to prevent multicast traffic from being generated to other interfaces that are not needed. I was looking at this command "ip pim passive"
Do you think I should enable this command in all the interfaces that are not required to have multicast traffic ?
Thanks to all in advanced!
Here is my router config:
