Hi

I would appreciate if someone could tell me if device Catalyst 4510R-E supports MLDv2 snooping when use of vlan mapping to a vlan tunnel QinQ design.

CPE--vlan100--Cat4500E--QinQ

MLDv2 snooping on vlan 100. Map the vlan 100 to e.g. 1:1000. Multicast router belongs to 1:1000. MLDv2 report is sent be CPE to join multicast group. Cat4500E snoops this report to build L2 forwarding entry for this multicast group.

Thank you for your response and where I could find the documentation concerning QinQ, Vlan mapping and MLDv2 snooping.
