Set the Multicast Scope TTL Value

Updated: October 16, 2008

Applies To: Windows Server 2008

You can use this procedure to set the multicast scope Time-To-Live (TTL) value, which specifies the number of routers (hops) that multicast traffic is permitted to pass through before expiring on the network. For each router (hop), the original specified TTL is decremented by one (1). When its TTL reaches a value of zero (0), each multicast datagram expires and is no longer forwarded through the network to other subnets.

Membership in the Administrators or DHCP Administrators group is the minimum required to complete this procedure.

To set the multicast scope TTL value

  1. Open DHCP.

  2. In the console tree, click the applicable multicast scope.

  3. On the Action menu, click Properties.

  4. In Time to live, specify a new value.
