Chapter 22 Configuring Multilink Point-to-Point Protocol Connections
Configuring MLP Bundles and Member Links
Configuration Example for Adding ATM Links to an MLP Bundle
Example 22-3 shows how to add ATM links to an MLP bundle. In the example, the virtual template
named Virtual-Template 1 is applied to PVCs 0/34, 0/35, and 0/36. Each of these PVCs is assigned to
MLP bundle group 1. Notice that all of the member links have the same encapsulation type. The router
does not support member links with different encapsulation types.
Example 22-3 Adding ATM Links to an MLP Bundle
Router(config)# interface Multilink 1
Step 8
Router(config-if-atm-vc)# encapsulation
{aal5mux ppp virtual-template number |
aal5ciscoppp virtual-template number |
aal5snap}
Configures the ATM adaptation layer (AAL) and
encapsulation type for an ATM virtual circuit (VC).
aal5mux ppp specifies the AAL and encapsulation type for
multiplex (MUX)-type VCs. The keyword ppp is Internet
Engineering Task Force (IETF)-compliant PPP over ATM. It
specifies the protocol type being used by the MUX
encapsulated VC. Use this protocol type for Multi-VC MLP
over ATM to identify the virtual template. This protocol is
supported on ATM PVCs only.
aal5ciscoppp specifies the AAL and encapsulation type for
Cisco PPP over ATM. Supported on ATM PVCs only.
aal5snap specifies the AAL and encapsulation type that
supports Inverse ARP. Logical Link Control/Subnetwork
Access Protocol (LLC/SNAP) precedes the protocol
datagram.
virtual-template number is the number used to identify the
virtual template.
Step 9
Router(config-if-atm-vc)# protocol ppp
virtual-template number
Enables PPP sessions to be established over the ATM PVC
using the configuration from the virtual template you specify.
Use this command only if you specified aal5snap as the
encapsulation type and you are configuring MLP on multiple
VCs.
number is a nonzero number that identifies the virtual
template that you want to apply to this ATM PVC.
Step 10
Router(config-if-atm-vc)# ppp multilink group
group-number
Associates the PVC with an MLP bundle.
group-number is a nonzero number that identifies the
multilink group. Valid values are:
• 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).
The group-number must be identical to the specified
multilink-bundle-number of the MLP bundle to which you
want to add this link.
