Configuration Example for Creating an MLP Bundle Interface
Example 22-1
OL-2226-23
The router automatically adds the ppp multilink and ppp multilink group commands to the
MLP bundle configuration.
shows a sample configuration for creating an MLP bundle interface.
Configuring MLP Bundles and Member Links
Purpose
Creates a multilink bundle. Enters interface configuration
mode to configure the bundle.
multilink-bundle-number is a nonzero number that identifies
the multilink bundle. For Cisco IOS Release 12.2(28)SB and
later releases, valid values are:
MLP over Serial—1 to 9999 (Release 12.2(28)SB and
•
later) or from 1 to 9999 and 65,536 to 2,147,483,647
(Release 12.2(31)SB2 and later).
Single-VC MLP over ATM—10,000 and higher.
•
Multi-VC MLP over ATM—1 to 9999
•
(Release 12.2(28)SB and later) or from 1 to 9999 and
65,536 to 2,147,483,647 (Release 12.2(31)SB2 and
later).
For releases earlier than Cisco IOS
Note
Release 12.2(28)SB, valid values are from 1 to
2,147,483,647.
Specifies the IP address and subnet mask assigned to the
interface.
address is the IP address.
mask is the subnet mask for the associated IP address.
(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.
If you configure this command on the bundle and its
Note
member links, specify the same identifier for both the
bundle and the member links.
(Optional) Configures the maximum delay allowed for the
transmission of a packet fragment on an MLP bundle.
delay-max specifies the maximum amount of time, in
milliseconds, that is required to transmit a fragment. Valid
values are from 1 to 1000 milliseconds.
(Optional) Enables interleaving of real-time packets among
the fragments of larger nonreal-time packets on an MLP
bundle.
(Optional) Disables packet fragmentation.
