Frame-Relay with two Routers(frame-relay switches) in frame-relay cloud

Hi,

I am using following lab in GNS3 with two routes (frame-relay switches) in Frame-Relay cloud.

The interaces of these two routers connected to each other have been configured with nni type. However, my PVCs are not coming up.

nni.PNG

configurations of the R1 and R6 are as follows:

_______________________ R1_______________________

interface Serial0/0

no ip address

encapsulation frame-relay

serial restart_delay 0

clockrate 1008000

frame-relay lmi-type cisco

frame-relay intf-type dce

frame-relay route 103 interface Serial0/1 553

!

interface Serial0/1

no ip address

encapsulation frame-relay

shutdown

serial restart_delay 0

clockrate 1008000

no frame-relay inverse-arp

frame-relay lmi-type cisco

frame-relay intf-type nni

frame-relay route 551 interface Serial0/0 103

__________________________R6_______________________

!

interface Serial0/0

no ip address

encapsulation frame-relay

serial restart_delay 0

clockrate 1008000

frame-relay lmi-type cisco

frame-relay intf-type dce

frame-relay route 301 interface Serial0/1 551

clockrate 1008000

no frame-relay inverse-arp

frame-relay lmi-type cisco

frame-relay intf-type nni

frame-relay route 553 interface Serial0/0 301

May be I am missing some command.Please help in resolving the issue.

Hello Daud,

After so many suggestions about corrections, I have lost track of what is your final state of configuration.

Please try to paste the following lines into your routers R1 and R6. They will reset the configuration of your S0/0 and S0/1 interfaces to default and configure them from scratch. If it does not help then please post the complete config of S0/0 and S0/1 interfaces from both R1 and R6. I have tested this configuration and it worked for me.

Hi,

Can you try this:

R1

int s0/1

frame-relay route 553 interface Serial0/0 103

R2

int s0/1

frame-relay route 551 interface Serial0/0 301

Regards.

May I ask if you enabled frame relay switching in global mode?

Hope this helps

Re: Frame-Relay with two Routers(frame-relay switches) in frame-

On a back to back frame relay, you have to turn LMI off by issuing a "no keepalive" on the interfaces. You may also have to convert these to point-to-point

links by moving your dlcis and addressing to a subinterface.

But, I also see your s0/1 is shut on R1....

Tried the "no keepalive" command too but with no result.

Here are the outputs of few show commands for R1 and R6:

Frame-Relay with two Routers(frame-relay switches) in frame-rela

Check this configs:

R1

frame-relay route 103 interface Serial0/1 553

frame-relay route 551 interface Serial0/0 103

R6

frame-relay route 301 interface Serial0/1 551

frame-relay route 553 interface Serial0/0 301

The mappings don't match. Should be the same 2 DLCI on each router just inverse them. R1 has 103 and 553 adn R6 has 301 and 551

Hope this helps

Dearest Peter and other friends,

Thankyou very much for your sincere help. At last my PVCs got up with the configuration suggested by Peter. Frame - Relay is really screwing my mind now a days, but many things got cleared to me with your kind guidence and help.

The thread with OSPF over NBMA has been left un pursued by me due to my engagement in the current thread. Now that this problem is solved, I will continue to this from tomorrow. Will request your help in case I got stuck at some point.

Once again, Thanks all for your support.
