access policies configured on the selected TMS zl device(s).
Figure 2-9. TMS-Firewall Tab, Access Policies > Multicast Subtab
Access policies for multicast traffic are aimed at traffic destined to a multicast
address between 224.0.0.0 and 239.255.255.255. Traffic destined to a multicast
address is delivered to any endpoint that has joined the group for that address.
Multicasting is often used for applications such as video streaming and some
routing protocols.
Note: Multicast routing is disabled by default, so creating a multicast policy has no
effect (except for traffic to/from self) unless routing is enabled.
