Multicast TTL Threshold—Enter the Time-to-Live (TTL) threshold of
packets being forwarded on an interface.
Multicast packets with a TTL value less than the threshold are not forwarded
on the interface.
The default value of 0 means all Multicast packets are forwarded on the
interface.
A value of 256 means that no Multicast packets are forwarded on the
interface.
Configure the TTL threshold only on border routers. Conversely, routers on
which you configure a TTL threshold value automatically become border
routers.
Select an interface, and click Edit. Enter the values of the fields described above.
Click Apply. The Running Configuration file is updated.
