We have a 2821 router with (3) VWIC2-2MFT-T1/E1. We are adding a fractional DS3 and I want to know how to "bundle" all of the cards to combine for a 9MB circuit.
Here is our existing 3MB multilink config. I will be adding 2 more VWICs on this router.
interface Multilink1
bandwidth 3072
ip address 10.x.x.10 255.255.255.252
ip route-cache flow
delay 100
no keepalive
ppp multilink
ppp multilink group 1
service-policy output VOICE-POLICY
interface Serial0/0/0:0
description MPLS 0/0/0
bandwidth 1536
no ip address
no ip redirects
ip flow egress
encapsulation ppp
ip route-cache flow
no fair-queue
ppp multilink
ppp multilink group 1
interface Serial0/0/1:0
description MPLS 0/0/1
bandwidth 1536
no ip address
no ip redirects
ip flow egress
encapsulation ppp
ip route-cache flow
no fair-queue
ppp multilink
ppp multilink group 1

Hi,
The additional T1s could just be added to the multilink interface the same way the two existing ones are configured.
There is one question I have however: Why are you mentioning a fractional DS3? Do you have additional equipment, which will multiplex the T1s into a fractional DS3? Or do you get a DS3 interface from a provider, which you would like to terminate on the router? In other words: how many cables do you connect to the 2800?
If you need a single DS3 interface, then the existing VWIC2-2MFT-T1/E1 will not be of much assistance.

Thanks Martin.
My mistake....its not a frac DS3 (that was our second option instead of installing the multiple T1's).
