• The unit ID number of the local unit is shown as the

LOCAL BRIDGE ID (Figure 39 (page 102)).

• The unit ID number of the Bridge unit to which the local unit

is linked is shown to the right of 'ASSOCIATED WITH

REMOTE BRIDGE ID'.

Configuring Multicast within a Layer-3 network

Within a typical Layer-3 network, consider a scenario in which Multicast

traffic must be routed in both directions between Fluidity-enabled, vehicle-

mounted radio transceivers, and the global gateway unit that governs data

traffic through the core network.

In the case above, since different multicast groups must be used for

upstream and downstream traffic, consider that group designator

224.5.5.5 is being used to route traffic from the vehicle radios to the global

gateway, and that group designator 224.5.5.6 is being used to route traffic

from the global gateway to the vehicle radios.

Apply the needed multicast rules by doing the steps that follow:

1. Identify all Mesh End units belonging to each subnet cluster in the

Layer-3 network.

2. Enable upstream (vehicle to infrastructure) Multicast traffic by

adding multicast route 224.5.5.5 / 5.a.b.c to the Mesh End unit in

each subnet cluster, where 5.a.b.c is the actual Mesh ID number

of the global gateway unit.
