First off, sorry for such a long email. But I figured I would give as much
information as possible upfront to try and give a clear picture about what I
have and what I am currently running.
Central Office Equipment:
Juniper M20 running v7.5R1.12
1x Link Services module (ls-3/0/0)
Customer Equipment:
Cisco 2611 running c2600-ipbase-mz.124-23
2x Eth (e0/0, e0/1)
4x T1 wic (s0/0, s0/1, s1/0, s1/1)
The following is the important parts of the config of the Cisco router
interface MFR0
description my interface
no ip address
frame-relay lmi-type ansi
frame-relay intf-type dce
interface MFR0.16 point-to-point
ip address 66.39.177.130 255.255.255.252
no cdp enable
frame-relay interface-dlci 16 IETF
interface MFR1
description Loop2
no ip address
load-interval 30
frame-relay lmi-type ansi
interface MFR1.16 point-to-point

no cdp enable
frame-relay interface-dlci 16 IETF
interface Ethernet0/0
ip address 66.39.177.133 255.255.255.252
half-duplex
interface Serial0/0
no ip address
encapsulation frame-relay MFR0
no arp frame-relay
interface Serial0/1
no ip address
encapsulation frame-relay MFR1
no arp frame-relay
If I place a cross over cable connecting S0/0 and S0/1, all the links come up.
So I am pretty sure that I have it all configured correctly. I think the
problem is with my Juniper setup, hence the reason I am posting this here.
Here is my Juniper config:
> show configuration chassis fpc 3 pic 0
mlfr-uni-nni-bundles 32;
> show configuration interfaces t1-1/1/0:0
description "Bendtel Test leg #1";
encapsulation multilink-frame-relay-uni-nni;
lmi {

}
unit 0 {

}
}
> show configuration interfaces t1-1/0/0:19
description "Bendtel Test leg #2";
encapsulation multilink-frame-relay-uni-nni;
lmi {

}
unit 0 {

}
}
> show configuration interfaces ls-3/0/0:0
dce;
encapsulation multilink-frame-relay-uni-nni;
unit 16 {
dlci 16;
family inet {

}
}
unit 17 {
dlci 17;
family inet {
address 10.100.100.1/30;
}
}
Here is the current status of all these interfaces

Here is the show chassis
jim at b1-bend-re0> show chassis hardware
Hardware inventory:
Item Version Part number Serial number Description
Chassis 20934 M20
...
FPC 3 REV 01 710-001292 AE7635 FPC
PIC 0 REV 01 750-007924 HM0123 1x Link Service(32)
...
For both t1s you can see that they show connected, but for some reason (that
escapes me) the ls interface shows "Hardware-Down" Does this mean the Link
services module is not turned up? To me it isn't clear.
Any help would be great!
Thanks
