original config between BB1 and R6
Greets again, i'm trying to validate if there's something specific i'm missing in original Layer2 configuration that should be applied to BB1 and R6.
In my case it seems they are connected over frame relay switch cloud connection...
I am running dynamips so here how my BB1 interfaces assigned :

=====================================================================================
Whenever i setup frame relay end-to-end connection between them and set "no keepalive" ping works fine !!!
Enable FR debug packets but there's not much chatter, perhaps something in my .net file or its something simple i'm not seeing ?

Looks OK to me. Can you paste how R6 is connected in your .net file. Can you also paste running config of interfaces for R6 and BB1.
If you debug LMI do you see anything?

Hey Daniel, here it is... i've noticed slot1 commented out for some reason...

Can you post configs from routers as well? Looks like there could be a mismatch in LMI type? Not sure what the unexpected pak message means but could have something to do with LMI type since it is working with back to back frame relay.
Can you please post the config of BB1 and R6? This could also be that the interface type on BB1 is dce, just a thought..

I don't think this is back to back frame-relay...at least I did not make it back to back, so I think you should remove the fram-relay intf-type dce.
qqabdal - I said FR back-to-back because I always thought that INE had r6-bb1 configured as FR back-to-back. However unsobill decided not to configure that way.
unsobill - How are you configured the FR switch? What is the status of PVC on bb1+r6?
In case you decide to configure them as back-to-back, this is your config.

andrius got it now..if this is not b2b, then he should remove the fram-relay intf-type dce..
Also, " frame-relay map ip 54.1.1.254 101 broadcast", needs to be
change to 100 or whatever PVC have you assigned to r6 end.
correct config below:
============================================================

I guess my question was : was it intended to be B2B and R6 missing "no keepalive" command, or there's mistake in default INE configuration file that i need to fix ?
unsobill - I guess it depends if there is a FR switch in between
But they never display how BB are interconnected.
However looking at the diagram above you can guess b2b, as there is only one dlci shown.
Andrius
on my .net file I am using a FRSW between BB1 and R6, so don't use the no keepalive command. You will only need this command if you have B2B...
I am using an old .net, so I am not sure if they recently changed to B2B frame.
Is it possible for you to share that old .net file so i can compare ?
Thanks.
I don't have it handy now, but it was something like this:
[[ROUTER R6]]
model = 3725
console = 2006
aux = 2105
wic0/0 = WIC-2T
s0/0 = FRO 6
f0/0 = SW2 f1/6
f0/1 = SW4 f1/6
[[ROUTER BB1]]
model = 3725
console = 2011
aux = 2110
wic0/0 = WIC-2T
s0/0 = FRO 11
s0/1 = BB3 s0/0
Should not be B2B FR!
Can you see if you can load Layer 2 configuration on all routers and BBB's and then try to ping from R6 to BB1 over DLCI 101?
You should use the .net from http://www.ine.com/resources/iosonpc.htm
Just make the IOS and dirs match with your computer. If you have any issues after that I'll help you out.
You right indeed, that initial config for BB1 worked with R6 without any changes...
Here is difference between BB1 initial config from there and BB1 Layer 2 config:
BB1 initial config :
!
interface Serial1/1
description Serial to FRS
no ip address
encapsulation frame-relay
no fair-queue
no shutdown
BB1 Layer 2 config :
!
interface Serial1/1
description Connected to R6
no ip address
encapsulation frame-relay
clockrate 64000
frame-relay intf-type dce
no shutdown
Apparently layer 2 config using "frame-relay intf-type dce" statement for some unknown reason...
Yes - as I said you should remove the frame-relay intf-type dce in order to have it working.
Glad you sorted it out.
