"Bonding" 4 T1's using ppp encapsulation and Multilink interface

[jasongrubbs]

We currently have 1 T1 connected to our facility. We are upgrading to a total of 4 T1's. We would like to bond them together to form a 6MB link to the building. Here is the config we have so far, is this right?

interface Multilink1
description Four T1 Circuits to DO
ip address 10.1.1.6 255.255.255.252
ppp multilink
ppp multilink group 1

interface Serial1/0:0
description T1 To DO
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
interface Serial1/1:0
description New T1 To DO
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
interface Serial1/2:0
description New T1 To DO
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
interface Serial1/3:0
description New T1 To DO

Looks good to me. We have a similar setup but use chap authentication due to upstream specifications and the config is the same.
