All things related to multicast

[Ramrao Deshpande <>]

Hi All,

How to handle following scenarios in
IGSv3 snooping switch

1. IGMPv3 Report message is received and contains three group record

• GR1 igmp join to multicast address G1
• GR2 igmp leave to multicast address G2
• GR3 igmpv3 current state record for G3

In the above case whether report message
should be sent router port or it can be discarded?

2. Interface is enabled with "Fast
Leave"  but that interface contains following hosts

• Host1-->IGMPv1 host joined to group G1
• Host2-->IGMPv2 host joined to group G1
• Host3-->IGMPv3 is sending leave message(state change record) to G1

Whether the interface to be pruned because
there is a leave message coming? or any other method to handle it.

Thanks and regards,

Ramrao G Deshpande
