1 Introduction
The first step is to modify the base interfaces configuration which use the PPP over ISDN to permit the use of the two
BRI channels. For this we need to execute the following sequence of commands.
Config>network ppp1
-- Generic PPP User Configuration --
ppp1 config>base-interface
-- Base Interface Configuration --
ppp1 Base IFC config>base-interface bri0/0 255 number-of-circuits 2
ppp1 Base IFC config>list
Base Interface
--------------------------
bri0/0
ppp1 Base IFC config>exit
ppp1 config>exit
Config>network ppp2
-- Generic PPP User Configuration --
ppp2 config>base-interface
-- Base Interface Configuration --
ppp2 Base IFC config>base-interface bri0/0 255 number-of-circuits 2
ppp2 Base IFC config>list
Base Interface
--------------------------
bri0/0
ppp2 Base IFC config>
Subsequently, we need to configure the multilink parameters in the PPP interfaces that are going to operate with
multilink. We strongly recommend enabling the option that only permits you to add new links to the multilink
if the PPP has been initiated from our side. In addition to the basic parameters (enable multilink and the option to
add links in outgoing calls only), you can configure the following:
• Activation Interval : This is the period of time that the traffic load on the line must remain above the activation
threshold so a new link is added.
• Deactivation Interval: This is the period of time that the traffic load on the line must remain below the activation
threshold so a link is released.
• Activation Threshold: This is the previously mentioned activation threshold.
• Deactivation Threshold: This is the previously mentioned deactivation threshold.
• Traffic Load : This is the direction of the traffic taken into account in order to calculate the amount of traffic on the
line (inbound, outbound or both).
• Max Links per Bundle: Maximum number of links that can be added to the same multilink.
We recommend that the remaining parameters take their default values.
Config>network ppp1
-- Generic PPP User Configuration --
ppp1 config>ppp
-- PPP Configuration --
ppp1 PPP config>multilink enable
ppp1 PPP config>multilink call-out
ppp1 PPP config>multilink activation interval 60
ppp1 PPP config>multilink activation threshold 80
ppp1 PPP config>multilink deactivation interval 90
ppp1 PPP config>multilink deactivation threshold 25
ppp1 PPP config>exit
ppp1 config>exit
Config>network ppp2
