Chapter 19 Configuring Multilink Point-to-Point Protocol Connections
Configuring MLP Bundles and Member Links
Adding an ATM Member Link to an MLP Bundle
You can configure up to 10 member links per MLP bundle for Multi-VC MLP over ATM. However, you
can configure only one member link per MLP bundle for Single-VC MLP over ATM.
To add ATM member links to an MLP bundle, enter the following commands beginning in global
configuration mode:
Step 8 Router(config-if)# encapsulation ppp Specifies Point-to-Point Protocol (PPP) encapsulation for the
interface.
Step 9 Router(config-if)# no ip address Removes any existing IP address from the main interface.
Step 10 Router(config-if)# ppp multilink Enables MLP on the interface.
Step 11 Router(config-if)# ppp multilink group
group-number
Associates the interface with an MLP bundle.
group-number is a nonzero number that identifies the
multilink group. Valid values are from 1 to 9999.
The group-number must be identical to the specified
multilink-bundle-number of the MLP bundle to which you
want to add this link.
Command Purpose
Command Purpose
Step 1 Router(config)# interface atm
slot/module/port
Configures or modifies the ATM interface you specify and
enters interface configuration mode.
Step 2 Router(config-if)# hold-queue length {in |
out }
Limits the size of the IP output queue on an interface.
length is a number that specifies the maximum number of
packets in the queue. Valid values are from 0 to 4096. We
recommend 4096 packets for all line cards. By default, the
input queue is 75 packets and the output queue is 40 packets.
in specifies the input queue.
out specifies the output queue.
Note We recommend that you configure this command on
all physical interfaces, except when using the ATM
OC-12 line card.
Step 3 Router(config-if)# interface atm
slot/module/port.subinterface point-to-point
Creates or modifies a point-to-point subinterface. Enters
subinterface configuration mode.
Step 4 Router(config-subif)# ppp chap hostname
hostname
(Optional) Identifies the hostname sent in the Challenge
Handshake Authentication Protocol (CHAP) challenge.
hostname is the name of the bundle group. This name
uniquely identifies the bundle.
Note If you configure this command on the bundle and its
member links, specify the same identifier for both the
bundle and the member links.
Step 5 Router(config-subif)# no ip address Removes any existing IP address from the main interface.
