D.3.1.1.3.3.1 Brouter Mode with VLAN Filtering Configuration
1) Use of the VLAN Filtering feature requires operation in Large Network Mode to
support the full 12-bit VLAN IDs field.
2) A maximum of 10 VLAN ID matches are supported. Unused VLAN ID match
fields must be set to values that DO NOT match any network VLAN IDs.
To configure Brouter Working Mode in a Point-To-MultiPoint network using VLAN Filtering with
CDM-IP modems and the CDD-564/L IP Quad Demodulator:
• At the Hub side, the only new configuration item required for the CDM-IP Hub Modem is to
enable VLAN Filtering. When enabled, the CDM-IP Hub Modem will transfer the first VLAN
ID to the 2-byte HDLC field.
• At each CDM-IP Remote Modem, VLAN Filtering must be enabled and the appropriate VLAN
IDs entered into the Match table.
• Figure D-9 shows a network comprised of a managed Hub Site and three Remote sites. In
this service, Remote Sites ‘A’ and ‘B’ share a common corporate service (Service ‘B’
Network) – a typical requirement in the oil and gas industry. All three sites employ a Shared
Voice Service. Sites ‘B’ and ‘C’ employ a Shared Internet Service. Each site additionally has
services (VLAN networks) that are exclusive to that site. The services provided in this
network are defined as follows:
Service Description VLAN ID Sites in Service
Shared Voice Services 0911 A, B, C
Shared Internet Services 1111 B, C
Management Services 1200 A, B, C
Corporate Network ‘A’ 0080 A
Corporate Network ‘B’ 0081 A, B
Corporate Network ‘C’ 0090 B
Corporate Network ‘D’ 0100 C
Corporate Network ‘E’ 0101 C
