Configuring MLPPP Fragmentation. When a packet is to be transmitted
across an MLPPP connection, the demand interface divides the packet into
fragments of equal length. If possible, the number of fragments equals the
number of active links in the MLPPP and are transmitted simultaneously over
each link. Fragmentation may also be controlled by the MTU setting of the
demand routing interface.
To enable fragmentation for MLPPP, enter the following command from the
demand interface configuration mode context:
ProCurve(config-demand 1)# ppp multilink fragmentation
Configuring the Minimum and Maximum Channels. When you config-
ure MLPPP for primary BRI interfaces, you must configure the minimum and
maximum number of B channels that can be aggregated into a single MLPPP
connection. Aggregated channels belong to BRI interfaces that are in the same
ISDN group, so you specify the minimum and maximum numbers from an
ISDN group configuration mode context. Enter:
Syntax: min-channels <number>
Syntax: max-channels <number>
Although the range for <number> is between 1 and 255, the actual number
of channels you can enter is limited by the number of BRI interfaces assigned
to the ISDN group. For example, if the ISDN group includes two BRI inter-
faces, the highest number of channels that can be used is 4 (two channels from
each interface.)
