How to Configure Layer 2 Features

This section contains the following procedures:

Configuring Distributed Multilink Point-to-Point Protocol, page 40

Configuring Multilink Frame-Relay, page 42

Configuring Distributed Multilink Point-to-Point Protocol

Configuring Distributed Multilink Point-to-Point Protocol (MLPPP) is presented in the following

sections:

• Create a Multilink Bundle, page 40

• Assign a Serial Interface to a Multilink Bundle, page 41

• Disable PPP Multilink Fragmentation, page 42

MLPPP allows you to increase the bandwidth of your network links beyond that of a single T1/E1 line

without having to purchase a T-3/E3 line. You can combine T1/E1 lines in a 1-Port CHOC-12 ISE line

card on a Cisco 12000 Series Router into a bundle that has the combined bandwidth of multiple T1/E1

lines. This is done by using an MLPPP link. You choose the number of bundles and the number of T1/E1

lines in each bundle.

An individual MLPPP bundle can span across multiple T1/E1s on the same line card, but bundles cannot

span across multiple line cards.

Note Distributed Multilink PPP is not supported across multiple Cisco 12000 series line cards.

A bundle can be composed of the following:

• 1 to 8 T1/E1 lines

• Individual T1/E1 line that can span across both ports

• Each T1/E1 component must be of equal bandwidth

For additional information, refer to the document, Configuring Media-Independent PPP and Multilink

PPP at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_c/dcppp.htm.

Create a Multilink Bundle

A multilink bundle consists of a maximum of 8 T1/E1s. To create a multilink bundle, use the following

commands beginning in global configuration mode:

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 ... 57 58
