Hi Experts

 

1- If we are using IGMP V1/V2 then in this what would be the destination address of IGMP report and leave messages?

2- Similarly what is the destintion address of IGMP query and group specific query?

 

Thanks for the input

Destination addresses:

Query:  224.0.0.1 (all-hosts) for both general and group-specific

Report:  the group address that is being reported on (i.e. if the group is 239.239.239.239, the destination address is 239.239.239.239)

Leave:  224.0.0.2 (all-routers)

 

From http://www.networksorcery.com/enp/protocol/igmp.htm and http://tools.ietf.org/html/rfc2236
