network with an OSM-12CT3/T1 module. An OSM-12CT3/DS interface has been configured with
MLPPP to carry two bundles of four T1 lines each. Each of these bundles goes out to separate remote
Cisco 7200 series routers, which each have one MLPPP bundle of four T1 lines. Another
OSM-12CT3/DS interface has been configured with MLPPP to carry two bundles of two T1 lines. One
of these bundles goes out to a Cisco 2500 series router and the other goes out to a Cisco 3800 series
router.

Creating a Multilink Bundle
To create a multilink bundle, perform this task beginning in global configuration mode:
Command
Step 1
Router(config)# interface multilink
bundle-id
Step 2
Router(config-if)# ip address address
mask
Step 3
Router(config-if)# encapsulation ppp
Step 4
Router(config-if)# ppp multilink
Step 5
Router(config-if)# [no] multilink-group
bundle-id
The following example shows how to create a multilink bundle:
Router(config)# interface multilink 1
Router(config-if)# ip address 10.0.0.0 10.255.255.255
Router(config-if)# encapsulation ppp
Router(config-if)# ppp multilink
Router(config-if)# multilink-group 1
Router(config-if)# CNTL/Z

Purpose
Statically configures link bundles.
Note The Multilink PPP command is available on serial
interfaces only.
Assigns an IP address to the multilink interface.
Enables PPP encapsulation.
(Optional) Enables Multilink PPP.
(Optional) Designates an interface as part of a multilink bundle.
bundle-id is the bundle number created with the interface multilink
bundle-id command.
