Multilink PPP
The Bay Networks implementation of PPP includes a multilink feature. Multilink
is similar to multiline; multilink, however, enables you to:
• Group lines of different speeds
• Preserve packet sequencing
• Distribute traffic more evenly among the data paths
• Monitor traffic volume
Multilink is particularly beneficial when you configure circuits to access BOD.
For more information about the Multilink PPP feature, see Configuring PPP
Services.
Bandwidth-on-Demand (BOD)
You can configure Bay Networks routers to access BOD to reduce line congestion.
This feature enables the router to access secondary dial-up lines when the primary
leased or dial-up line becomes congested. The router can then transmit excess
traffic over the secondary switched lines.
For more information about BOD, see Configuring Dial Services.
Configuring Multiline Services
The method you use to configure a multiline circuit depends on the types of lines
you need to group.
• For information on how to group logical lines into a multiline circuit, go to
“Grouping Logical Lines into a Multiline Circuit” on page 9-13
.
• For information on how to group physical lines into a multiline circuit, see
“Grouping Physical Lines into a Multiline Circuit” on page 9-6
or
“Adding Physical Lines to a Circuit” on page 9-7.
