Note: I initially sent this to the Juniper-NSP list. I was told by Nilesh
Khambal (Juniper Engineer) that I have setup the Juniper side correctly. So,
I'm hoping someone here might have a little more information on the Cisco side
of it all.
TIA!
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

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
