Hello folks, I have question with regards to IGMP on the Avara ERS 4800s. I am looking at the following commands and was wondering how they relate to each other if they do at all
1. ers(config)#vlan igmp unknown-mcast-no-flood {enable|disable}
2. ers(config)#ip igmp multicast-filter-mode {enable|disable}
I know that the first command enables unknown multicast filtering but I am not sure about the second command and what it does? The documentation doesn't seem to be very clear with regards to the purpose of the second command. Is the second command required in order for the first command to work? Thanks for all the help.
