Subject: [Ipsec] Multicast Traffic support within IPSec VPN Tunnel?

Hi,

Can IPSec VPN Site-to-Site tunnel carry Multicast traffic or Broadcast
traffic with in the tunnel?

If yes, is it just the bare IPSec protocol which can allow Multicast
or Broadcast traffic to pass through the tunnel or do GRE or any such
protocol is mandatory?

If No, why IPSec by itself can not carry Multicast or Broadcast
traffic through the tunnel?

Looking forward for reply.

Thanks and Regards,
Madhukesh.
