Using MP

Enabled as a Multilink PPP Link,

Use as a dedicated Multilink PPP link? [No]: yes Multilink PPP net for this Multilink PPP link [1]? 9

NOTE: PPP configuration will be obtained from the Multilink PPP net. It is NOT necessary to configure PPP for this net!

Note: You cannot con®gure PPP parameters for dedicated links from this prompt. Dedicated links use the existing MP interface's PPP con®guration.

By answering ªYesº to the question ªUse as a dedicated Multilink PPP link?º the link becomes dedicated to the speci®ed Multilink PPP interface (9 in this example). In this case, the link must be used for an MP bundle and must join the speci®ed MP interface. The link cannot be used as a regular PPP dial circuit.

Answering ªNoº to ªUse as a dedicated Multilink PPP link?º will allow this PPP dial-circuit to join any MP interface. At least one PPP dial-circuit must be a dedicated link to an outbound MP interface.

A dedicated PPP dial circuit obtains all PPP parameters (LCP options, authentication, and others) from its MP interface. MP enabled PPP dial circuits joining the same MP bundle must negotiate the same LCP parameters and authentication name.

4. Con®gure the MP interface. The ªDialout MP link netº should be a dedicated

 

PPP dial circuit.

 

Config>net 9

 

Circuit configuration

 

MP config: 9>set calls out

 

Dialout MP link net for this MP Net [0]? 7

 

MP config: 9>

 

Protocols, BAP, BRS, WAN restoral, WAN reroute, and dial-on-demand are all

 

run on the MP interface and not the PPP dial circuits.

Con®guring MP on PPP Serial Links

To con®gure MP on a PPP serial link, you enable MP on the interface using thenet

command. The link obtains its PPP con®guration from the MP net.

Example:

Config> net 1

PPP 1 Config> enable MP

Multilink PPP net for this Multilink PPP link [1]? 8

NOTE: PPP configuration will be obtained from the Multilink PPP

net. It is NOT necessary to configure PPP for this net!

PPP 1 Config>

 

Con®guring MP on Layer-2-Tunneling Nets

To con®gure MP on an L2TP net, you enable MP through the L2TP encapsulator.

You then must con®gure the same PPP negotiation parameters (see ªCon®guring

L2TPº in Using and Con®guring Features) for information about all nets joining in a

single bundle.
