Hello!

You have a sample configuration. If you are using MPLS and want MPLS MPPP then there are some restrictions (this document will help: http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/mplsdmlp.html#wp1059434)

You need the config below in both sides RouterA and RouterB

interface Multilink1

ip address XXX.XXX.XXX.XXX 255.255.255.252

no cdp enable

ppp multilink

ppp multilink fragment disable

ppp multilink group 1

!

interface Serial0/0

bandwidth 2048

no ip address

encapsulation ppp

no cdp enable

ppp multilink

ppp multilink group 1

!

interface Serial0/1

no ip address

encapsulation ppp

no cdp enable

ppp multilink

ppp multilink group 1

The utility of MPPP is that it allow to bundle multiple E1/T1 link in one logical interface with and increased bandwidth. For example if you have 2 E1 bundled in 1 MPPP then you have 4Mbps interface (2 x 2Mbps).

Please tell if it is working or need you need more info.

Cheers,

Hello!

What IOS do you have? I wrote version 12.0, but can you put here the full name to see the features?

command. pls explain..

Hi Vinoth

I feel your IOS is not supporting the multilink interface related commands and doesnt support multilink.

Can you try doing an upgrade to the IOS and config the multilink.

you can make use of this link to get your router configured with multilink...
