Multi Frame Relay

Can someone help me out on why this configuration doesnt work?  It is to connect one location to another via (2) T1's.  i believe it has something to do with the interface-dlci command, since it is showing inactive, but I dont know what im doing wrong

Router A:
!
interface Serial0/2/0:0
 description Bonded T1 - 1 of 2
 bandwidth 1536
 no ip address
 no ip redirects
 no ip proxy-arp
 encapsulation frame-relay MFR1
 no arp frame-relay
!
interface Serial0/2/1:0
 description Bonded T1 - 2 of 2

where did you get the DLCI numbers? where they assigned by the carrier? Are the physical circuits up?

Post the output of "show frame pvc" and show frame map" from both routers.

I did not get the DLCI numbers from the carrier.  I only have Circuit ID's  Yes The physical circuits are up
The carrier has to provide you with the DLCI numbers. The router and the local frame relay switch communicate using that DLCI- it identifies the PVC. The numbers may be different on the 2 sides. You may be able to figure it out using the commands I gave you- let's look at the output.
I removed the  frame-relay interface-dlci 101 IETF command since the 101 is a number I made up and the commands have blank returns.

Are you connecting to a frame cloud or are these T1 dedicated circuts between the two sites?
Dedicated Circuits BTW the two locations
I'm reading up on this.  I had it wrong about the carrier but still, the DLCI has to be matched by something on the other side. I'm wondering if one side has to be set for frame relay switching.

What's the output of "show frame multilink" on both sides?
Just for fun, put the same DLCI number on both sides.

you can also see what comes of "debug frame multilink"
FPMG#debug frame multilink
This may severely impact network performance. Continue? [confirm]

Well, it depends how busy the router is. Is it in production right now? Try "show proc cpu" and see how busy it is.

You can stop the debugging with "u all"
I made the DLCI 500 on both sides.  Here is some output

FPMG#show frame multilink
Bundle: MFR1, State = down, class = A, fragmentation disabled
 BID = MFR1
 Bundle links:
  Serial0/2/1:0, HW state = up, link state = Add_sent, LID = Serial0/2/1:0
  Serial0/2/0:0, HW state = down, link state = Down, LID = Serial0/2/0:0

FPCoLo#show frame-relay multilink
Bundle: MFR1, State = down, class = A, fragmentation disabled
 BID = MFR1
 Bundle links:
  Serial0/3/0:0, HW state = down, link state = Down, LID = Serial0/3/0:0
  Serial0/3/1:0, HW state = up, link state = Add_sent, LID = Serial0/3/1:0
I think giltjr said clearly what I was moving toward- put the same DLCI number on both sides. the doc he pointed to is good.

What is output of "sho frame-relay pvc" ?
ok the command "No keepalive" got the MFR interface up...However I screwed up and followed the wrong part of the example and typed in clock speed 64000 on the S0/2/0 interface and it is now down on the router, how do I correct that?
Just type "no clock speed 64000"
Ok it looks like I am working.  One more question.  If I am downloading a file across this connection, should I be getting it at 3.0 Mbps or 1.5?  Im currently only getting it at half of 3.0
When you do "show frame-relay multilink" do both links show as being up?
Nevermind, It was a DNS issue.

Thanks for all the help!
frame-relay multilink output-threshold
To configure the number of bytes that a bundle link will transmit before the load-balancing mechanism causes transmission to roll over to the next available link, use the frame-relay multilink output-threshold command in interface configuration mode. To reset this value to the default setting, use the no form of this command.

frame-relay multilink output-threshold [bytes]

no frame-relay multilink output-threshold

Syntax Description
 bytes
 Number of bytes that a bundle link will transmit before the load-balancing mechanism causes transmission to roll over to the next link. Range: 20 to 2147483647. Default: 300.
 
Command Default
The number of bytes transmitted is set at 300.

Usage Guidelines
Multilink Frame Relay enables load balancing across bundle links that are in the same bundle. When a bundle link has reached its output threshold, transmission rolls over to the next available bundle link in the bundle.

The output threshold mechanism applies only when the bundle interface is using FIFO output queueing. When the bundle interface is not using FIFO output queuing, the algorithm for choosing a bundle link interface for output selects the bundle link that has the empty or shortest output queue.

The default output threshold is 300 bytes. This default value will work effectively if all the bundle links in the bundle have the same speed. To efficiently use bundle links with different speeds, use the frame-relay multilink output-threshold command to adjust the output threshold of the links as appropriate.

The frame-relay multilink output-threshold command can be used on the bundle interface and the bundle links. If the command is used on the bundle interface, the configured output threshold will apply to all bundle links in the bundle. If the command is used on a specific bundle link, the output threshold will overwrite the current setting for that bundle link.

Examples
The following example shows how to configure the bundle link output threshold at 600 bytes. When the bundle link reaches the threshold, transmission will roll over to the next link.

interface serial0
 encapsulation frame-relay mfr0
 frame-relay multilink output-threshold 600
Oh, you fixed it... D'oh!
