question about inactive frame-relay connection?

Hello,

i'm configuring a frame relay connection between  two routers, and when i typed sh frame-relay map on both routers i got this output:

Serial0/0 (up): ip 140.1.245.5 dlci 405(0x195,0x6450), static,

              broadcast,

              CISCO, status defined, inactive

Serial0/0 (up): ip 140.1.245.4 dlci 504(0x1F8,0x7C80), static,

              broadcast,

              CISCO, status defined, inactive

and also i couldn't ping from any router to the other one, here is the configurations of the two router

R4(config-if)#interface Serial0/0

                     ip address 140.1.245.4 255.255.255.0

                     encapsulation frame-relay

                     frame-relay map ip 140.1.245.5 405 broadcast

                     frame-relay interface-dlci 504

                     no frame-relay inverse-arp

R5(config-if)#interface Serial0/0

                    ip address 140.1.245.5 255.255.255.0

                     encapsulation frame-relay

                     frame-relay map ip 140.1.245.4 504 broadcast

                     frame-relay interface-dlci 504

                     no frame-relay inverse-arp interface Serial0/0

by the way, the other configuration of both routers is just the basic configuration

and also i want to add something else, that router 4 is 2600 series  running IOS version 12.2(8r) and System image file is "flash:c2600-adventerprisek9-mz.124-23.bin"

router 5 is 2600 series  running IOS  Version 12.2(8r)  System image file is "flash:c2600-adventerprisek9-mz.124-12.bin"

so please can you tell me how i can resolve this problem,

thanks

Best Regards

Can you tell us how these routers are connected? The configuration seems to suggest that there is a frame relay switch that connects them. I am wondering whether that is the case or whether they are actually connected back to back. If you can clarify the connectivity we may be able to give you better answers.

Hi,

is this a back to back Frame-relay config ?

Then do this:

R4(config-if)#interface Serial0/0

                     ip address 140.1.245.4 255.255.255.0

                     encapsulation frame-relay

                     no keepalive

                     frame-relay map ip 140.1.245.5 405 broadcast

                     no frame-relay interface-dlci 504

                     no frame-relay inverse-arp

R5(config-if)#interface Serial0/0

                    ip address 140.1.245.5 255.255.255.0

                     encapsulation frame-relay

                     no keepalive

                     no frame-relay map ip 140.1.245.4 504 broadcast

                     frame-relay map ip 140.1.245.4 405 broadcast

                     no frame-relay interface-dlci 504

                     no frame-relay inverse-arp

 

Don't forget to no shut the interfaces.

Regards.

thanks for your reply,

when i tried the config of Alain and type the command sh fame-relay map i got this output on both routers:

R4#sh frame-relay map

Serial0/0 (up): ip 140.1.245.5 dlci 405(0x195,0x6450), static,

              broadcast,

              CISCO

R5#sh frame-relay map

Serial0/0 (up): ip 140.1.245.4 dlci 405(0x195,0x6450), static,

              broadcast,

              CISCO

and also i found the interface is up and the protocol is up on both routers but i still coudn't ping from both to the other one

Hi,

Are you connected to a Frame-Relay switch?

Can you post output from sh frame-relay PVC | in STATUS

Regards.

Alain

Hi,

sh frame-relay PVC | in STATUS

DLCI = 405, DLCI USAGE = LOCAL, PVC STATUS = STATIC, INTERFACE = Serial0/0

Hi,

you didn't answer if you were using a Frame-Relay switch ?

Hi,

sorry i forgot, this is a frame-relay switch

If you're configuring back-to-back frame relay you don't need to go through a frame relay switch. The whole point behind back-to-back is to configure a frame relay connection without a frame relay switch. This is why you use the 'no keepalive' command, because otherwise the routers would expect to hear keepalives from the frame relay switch via LMI. Also, as Cadet put in his configuration to you, you will need to use the same DLCI on each side of the back-to-back frame relay connection, because there is no switch to inform it on which different DLCI it should sent it out on.

Hi,

then put the keepalive command under each interface and configure appropriate frame map command with correct dlci and then post output of :

sh frame lmi

sh frame map

sh frame pvc | i STATUS

Regards.
