The most important part of configuring multiline is setting the PVC DLCI

number. This number identifies each PVC, thereby specifying a path for the router

to direct data to the network. For each frame relay PVC that you configure, check

that PVCs with the same destination have the same DLCI number.

For more instruction on configuring multiline mode, see “Grouping Service

Records for Multiline Mode” on page 4-27.

Traffic Distribution Between Data Paths

To distribute traffic between multiline data paths, you can use one of two methods:

• Random distribution

• Address-based distribution

Random Distribution

Random distribution means that as the router sends out each packet, it alternates

between the lines. This option determines which line the packet uses based on a

randomly assigned number. For each outbound packet, the router generates a

random number that designates the line to use.

Random distribution balances traffic across lines and lets the router use the two

lines efficiently. Because packets travel on different paths, they arrive at the

destination out of sequence, and the upper-layer protocols, for example, IP and

Open Systems Interconnection (OSI), have to resequence the information. Some

protocols cannot tolerate packets arriving out of sequence, so be sure this option is

appropriate for your application.

Note:

If you use multiline, packets traveling on the two paths may arrive at

their destination out of sequence. Some protocols do not tolerate packets

arriving out of sequence and, as a result, you may experience poor

performance or failures.
