2.5 Point to Multi-Point
In this application, the traffic is transported to remote destinations based on the incoming
VLAN C-Tag. To support the point to multipoint management, the IP Proxy mode is used
with device A acting as the server and B/C acting as clients.
In this application, WCM1800-A is operating with VLAN mode enabled and is operating
LAN Port 2 in VLAN Trunk Mode. Incoming packets must be tagged and are switched
based on the incoming tag. Individual VLAD ID’s or ranges may be allocated to each
VCG. In this case, VLAN 101 and 102 are allocated to VCG1 serving remote device B,
whilst VLAN 103, 104 are allocated to VCG2 serving remote device C.
The remote devices, B and C are both operated in VLAN mode but with the LAN ports in
access mode stripping the tags from egress packets and tagging packets on ingress.
