configuring Multilink PPP

Hi,

I need some info on configuring a cisco 2811 with 3 T1 lines bound as
one, as far as I have read everywhere it seems like Multilink PPP is
the best options.

Can someone give me me some information and sample confg on this topic.

questions:

1) Can Cisco VWIC 2MFT-T1 - will this wic be good for the config.(it
has 2 physical ports) as I would need 2 of these for 3 T1's

2) After configuring Multilink PPP on my router do I need to ask the
provider to configure their side as well, as my router will only access
internet.

3) what exactly is the config I need and what config I need to give the
provider.

All responses are really appreciated.

Thanks

RTR

FYI, multilink PPP must be configured on both sides and all 3 T1s must
be on the same device (and DS3 for the provider) so make sure you order the
T1s as "bonded".

Hi RTR,

I don't know if this is any help to you but I happened to do something
similar a few weeks ago for a UK customer, albeit with 2 x E1's. FYI the
Telco provided me with a sample config so I recommend that you speak to
yours to clarify the position.

1) I used a 2801 with the VWIC 2MFT-E1 - you shouldn't have a problem
with a T1. I used 1 x existing 3640 for my config.

2) The Telco configured their end at the same time I did mine. They
stated that the Multilink had to be done this way as you can hit
problems if you do them out of sync.

3) My config was as follows:

Note that the Serial interfaces are assigned to a Multilink group. The
Serial Interfaces have no ip address. The Multilink interface has 1 x IP
address that is for the Multilink group.

!
controller E1 3/0
framing NO-CRC4
channel-group 0 timeslots 1-31
!
controller E1 3/1
framing NO-CRC4
channel-group 0 timeslots 1-31
!
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 Serial3/0:0
bandwidth 2048
no ip address
encapsulation ppp
no cdp enable
ppp multilink
ppp multilink group 1
!
interface Serial3/1:0
no ip address
encapsulation ppp
no cdp enable
ppp multilink
ppp multilink group 1
!

Hope that helps.

Just for clarification, the statement below doesn't make sense. It
should have read - I used a 3640 with the VWIC not a 2801. Apologies for
any confusion in my earlier reply.
