Using the AliasOptions and BroadcastOptions Properties

Table 7.2 summarizes the effect of each possible combination of the values of the
BroadcastOptions and AliasOptions properties.

Values

lcaAliasForSelectorConflicts

lcaAliasForUnicasts

lcaBroadcastNever

This is the default combination

applied to all LNS connections.

This combination allows for
subnet/node addressing and

multicast group addressing, but

it does not allow the use of
broadcast addressing.

This combination splits a

single multicast connection

into multiple unicast
connections using subnet/node

addressing, and allocates

aliases to the output network
variable. If no aliases are

available, LNS will use group

addressing instead.
