Frame Relay

[Flow21]

Hi

How do I establish a Frame Relay connection between two serial ports (ports on two Cisco 1720) without anything in between?

Hi

This is just from the top of my head, so don't expect it to work...
However it might give you some clues on how to get it all done.

Router A
int s0
ip address 10.0.0.1 255.255.255.0
encap frame-relay

Router B
frame-relay switching
int s0
ip address 10.0.0.2 255.255.255.0
encap frame relay
frame-relay map dlci 100

Hope this helps you a bit, if you still don't make it work, I can look up the correct way for you later.

Here you find an example for a Frame Relay Back-to-Back configuration (you just need a DCE and a DTE serial cable):

This helped me perfect folks, but how can I check if there´s
a conn. ?
The show commands show all the relevant things, but i can´t ping

 

[ak8899]

What's the interface status? (sh int serial x)
Line and protocol up?
Did you assign correct DLCI?

 

[jeter]

type this ( sh ip int brief) this will show the stat of all your interfaces.

or sh int serial 0 or what ever the interface is. Jeter@LasVegas.com

Both are up line and protocol!!

Status is static but i can´t ping!

Do you ping from one router to the other or from your pc to the remote router? Can you post the config's?

 

[Flow21]

I used the config you gave me:

http://www.cisco.com/warp/public/125/frbacktoback.html

I ping from router to router

 

[ak8899]

i just wanted to check IP addresses, clock setting, etc.

OK here they are:

Router 1:
!
interface Serial0
description connection to Internet
no ip address
encapsulation frame-relay
no keepalive
fair-queue
!
interface Serial0.1 point-to-point
description connected to CI-Labor-2
ip address 111.1.1.1 255.255.255.0
frame-relay interface-dlci 101
!
router rip
version 2
network 111.0.0.0
no auto-summary
!
ip classless
ip route 13.1.1.0 255.255.255.0 111.1.1.2 name CI-Labor-2
no ip http server
no ip pim bidir-enable

Router 2:

!
interface Serial0
description connection to Internet
no ip address
encapsulation frame-relay
no keepalive
fair-queue
!
interface Serial0.1 point-to-point
description connected to CI-Labor-1
ip address 111.1.1.2 255.255.255.0
frame-relay interface-dlci 101
!
router rip
version 2
network 111.0.0.0
no auto-summary
!
ip classless
ip route 12.1.1.0 255.255.255.0 111.1.1.1 name CI-Labor-1
no ip http server
no ip pim bidir-enable

 

[ak8899]

specify a clock rate on one of the routers:
interface Serial0
no ip address
encapsulation frame-relay
no keepalive
clock rate 64000
