PPP Multillink and VWIC-2MFT-T1

[mark-johnson]

Hello,

I am trying to find out for sure if the VWIC-2MFT-T1 card will support ppp multilink. We have a situation where we will be linking 4 T1s between our site and a remote site. I was thinking of placing a 3600 series router at both ends and dropping 2 VWICs in them to handle the 4 T1s. Before we go ahead and buy it all, I have been trying to find out if this is supported by the card. Amy reccomendations are also helpful. Thanks in advance.

Mark,

I'm successfully using the 2MFT-T1 today with PPP Multilink on 2 T1's in a 3640. I see no reason why it wouldn't work for 4.

Happy Routing.

Could you send me your config on how you set up the controller's...I am lost on how to create serial interfaces with this card...

Here are a few steps.

1) Enter config mode ( config t )

2) type 'controller t1 (number)

3) setup the linecode and the framing here.

4) then you can type channel-group (number) timeslots (number of channels) speed 64

This will then create a Serial interface for you using the channels you alloted in the group. Hope this helps.

Mark,

Just a word of caution...This might not have anything to do with 3600 series routers, but only something to do with the IOS (bug) and specific hardware. I had a customer who had a 3745 router with NM-HDV and VWIC-2MFT-T1 used on a PPP multilink. The router crashed every time we sent a packet across the link. Finally the only IOS that fixed this problem was 12.3.9T which came out weeks ago..
