Element		Description
Enable IP Multicast		Select to enable multicast transmissions across your GRE tunnels.
		IP multicast delivers application source traffic to multiple receivers
		without burdening the source or the receivers, while using a
		minimum of network bandwidth.
Rendezvous Point		Only available if you selected the Enable IP Multicast check box.
		If required, you can enter the IP address of the interface that will
		serve as the rendezvous point (RP) for multicast transmission.
		Sources send their traffic to the RP. This traffic is then forwarded to
		receivers down a shared distribution tree.
Save button		Saves your changes to the server but keeps them private.
		Note To publish your changes, click the Submit button on the
		toolbar.
Close button		Closes the Site-to-Site VPN window.
