bundle. This enables you to issue a single command for the entire bundle instead of
having to issue individual commands for each member link in the bundle.
For example, the following commands configure MLPPP fragmentation and reassembly
for all member links in the bundle group1.
host1(config)# interface mlppp group1
host1(config-if)# ppp fragmentation 128
host1(config-if)# ppp reassembly 1590
host1(config-if)# exit
host1(config)#
Any member links added to the bundle after you issue an MLPPP configuration command
in the bundle context are not affected by the command. For example, if you add a member
link to the group1 bundle after you issue the
ppp fragmentation or ppp reassembly
command, MLPPP fragmentation and reassembly for this link and any member links
subsequently added to the bundle is not enabled.
Configuring Multiclass MLPPP
Multiclass MLPPP enables you to fragment data packets of different priorities into multiple
classes in an MLPPP bundle. It also enables you to send high-priority packets between
fragments of larger, lower priority packets. Multiclass MLPPP ensures that high-priority,
delay-sensitive traffic, such as voice and video, are received in the proper sequence.
For information about multiclass MLPPP, see “Configuring Multiclass Multilink PPP” on
page 345.
Monitoring MLPPP
Use the commands in this section to display information about MLPPP interfaces.
You can set a statistics baseline for MLPPP serial (member link) or bundle (multilink)
interfaces using the
baseline ppp command. Use the delta keyword with the show
commands described below to display statistics with the baseline values subtracted.
After you configure multilink PPP, you can use the show ppp interface commands to
display configuration and statistics information about MLPPP and MLPPP fragmentation
and reassembly.
You can use the output filtering feature of the show command to include or exclude lines
of output based on a text string you specify. For details, see section show Commands in
JunosE System Basics Configuration Guide .
NOTE: The E120 and E320 routers output for monitor and show commands is identical
to output from other E Series routers, except that the E120 and E320 routers output
also includes information about the adapter identifier in the interface specifier
(slot/adapter/port).
