To route unicast/multicast addresses specifically into a GRE tunnel, use the CLI command ip addroute
Example
# ip addroute 225.0.0.2 255.255.255.255 4
The above configuration will forward multicast datagrams with IP address 225.0.0.2 from the STM
SatLink VSAT LAN interface to the GRE tunnel identified by the specific GRE interface ID..
Forwarding of multicast IP traffic from DVB interface to GRE interface is not supported
in the current release
As shown by the CLI command
ip show -mcast
# ip show -mcast
