Chapter 22 Configuring Multilink Point-to-Point Protocol Connections
Valid Ranges for MLP Interfaces
Using unnumbered IP interfaces enables you to work around IP problems and configure an IP address
on an MLP-enabled link. The following example shows how to configure Multi-VC MLP over ATM
using an unnumbered IP interface:
!
interface Multilink1
ip unnumbered Loopback0
peer default ip address pool mlpoa_pool
ppp chap hostname m1
ppp multilink
ppp multilink group 1
!
interface atm 2/0/0
no ip address
!
interface atm 2/0/0.1 point-to-point
pvc 0/32
ppp multilink group 1
vbr-nrt 128 64 20
encapsulation aal5mux ppp Virtual-Template1
!
!
interface atm 2/0/0.2 point-to-point
pvc 0/33
ppp multilink group 1
vbr-nrt 128 64 20
encapsulation aal5mux ppp Virtual-Template1
!
interface Virtual-Template1
no ip address
keepalive 30
ppp max-configure 110
ppp max-failure 100
ppp multilink
ppp timeout retry 5
!
ip local pool mlpoa_pool 100.1.1.1 100.1.7.254
