Multicast Routes parameters

Digi TransPort routers support multicast routes, allowing them to route packets to multicast
group addresses. Up to 20 different static multicast routes may be configured.
Static multicast routes must be used in conjunction with the IGMP parameter on the outbound
interface. For example, after configuring a static multicast route for multicast traffic via PPP 1, the
IGMP parameter in Configuration – Network > Interfaces > IGMP needs setting to ON.
Multicast routing is configured using a table with the following parameters.
