disable multicast moh on wan

Posted by Andy on April 21, 2009

To prevent the central-site audio stream(s) from traversing the WAN, use one of the following methods:

•Configure a maximum hop count

Configure the central-site MoH audio source with a maximum hop count (or TTL) low enough to ensure that it will not stream further than the central-site LAN.

•Configure an access control list (ACL) on the WAN interface

Configure an ACL on the central-site WAN interface to disallow packets destined to the multicast group address(es) from being sent out the interface.

•Disable multicast routing on the WAN interface

Do not configure multicast routing on the WAN interface, thus ensuring that multicast streams are not forwarded into the WAN.
