Additionally, HDLC addresses can be used to select or filter multicast traffic on the hub
outbound common carrier. Hub CDM-IP 1 has two multicast routes defined with two
Next Hop HDLC addresses, 0x10 and 0x11. Remote CDM-IP 2 has RX HDLC Address
0x10 enabled to receive one of the multicast streams. Remote CDM-IP 3 has RX HDLC
Addresses 0x10 and 0x11 enabled to receive both of the multicast streams.
Additonal remote sites can be added through a dedicated RX Only CDM-IP at the hub for
each remote.

Full or partial “Mesh Network” Configuration – The “Star Network” configuration
works for a “hub-centric” network, where all traffic is either coming to, or from, one
central hub. There are several ways to send traffic between remote sites.
