Good afternoon - I am turning up a circuit (4 t1's actually, bonding them together) and I am a little unsure how to do this. This will not be a point-to-point circuit, but 4 t1's bundled into a multilink interface. This is a Cisco 2951 ((C2951-UNIVERSALK9-M), Version 15.1(3)T1) with 3 open wic slots. I have 1 VWIC2-2MFT-T1/E1 card and 2 VWIC2-1MFT-T1/E1 cards.
We are controlling BGP, and this is on an MPLS network.
I think I have it configured correctly, but I was unsure if I put the total bandwith on the multilink interface or if I it on each serial interface respectfully.
I will have it programmed as such:
card type t1 0 1
card type t1 0 2
card type t1 0 3
Controller t1 0/1/0
framing esf
linecode b8zs
clock source line
channel-group 0 timeslots 1-24
Controller t1 0/1/1
framing esf
linecode b8zs
clock source line
channel-group 0 timeslots 1-24
Controller t1 0/2/0
framing esf
linecode b8zs
clock source line
channel-group 0 timeslots 1-24
Controller t1 0/3/0
framing esf
linecode b8zs
clock source line
channel-group 0 timeslots 1-24

Any input is greatly appreciated; I'm pretty sure I have this set up correctly
Thanks!

Looks right to me. Your provider needs to know they're going to bond them with you in order for the multilink interface to come up.

That looks right to be. The bandwidth statement goes on the interface with the IP address. It's used by routing protocols and QoS commands to make load calculations.
Are you not running an inside routing protocol like OSPF or EIGRP? You might look int the new EIGRP-OTP stuff. It really helps with BGP based MPLS networks.

John and hypnotoad - Thank you for the quick replies! I am using eigrp, I just failed to put that in the config
