Problems with frame relay (Lab scenario)

[t0mm0]

currently have a Cisco 1700 connected to a 2600 via their serial ports.

Meanwhile I'm trying to configure frame relay between the two devices, but not getting any joy.

I either get the ports are up, but can't ping to each other OR as in this scenario the ports are in up/down stautus.

I've completely changed the config since the first scenario and so the following config outlines my current situation;


===========================================================

Cisco 2600


testpod1#sh run int s0/0
Building configuration...

Current configuration : 205 bytes
!
interface Serial0/0
description Interface to Testpod2
ip address 192.168.2.101 255.255.255.0
encapsulation frame-relay
frame-relay map ip 192.168.2.102 220 broadcast
no frame-relay inverse-arp
end


testpod1#sh ip int br
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 10.10.1.200 YES NVRAM up up
Serial0/0 192.168.2.101 YES manual up down



-----------------------------------------------------------

Cisco 1700


Testpod2#sh run int se0

no frame-relay inverse-arp
frame-relay intf-type dce
end


Testpod2#sh ip int brief

HELP!!

There are so many things wrong with that set up...where shall I begin?
You need a frame relay switch in between, first of all. You cannot set up frame relay between two routers in a point to point config like that without a frame relay switch in between! Also, you have the same DLCI configured on both routers! Read the other posts in here that are recent about frame relay!

That's not true Burt, you can indeed set up back to back frame-relay. You do not need to have the frame-relay switch between, although in order to emulate a service provider frame switch it may make more sense to do so. I do this all the time in my CCIE lab. As a matter of fact, it is a requirement. Here is the link to the rather easy configuration to do so.

My bad...wow...did not know that! Thanks for clearing that up!
Okay, T0mm0---looks like you just need to enable frame-relay switching on the 1700.

Awesome guys!!

Post your posts got me thinking.

Burts got me thinking on the vibe that the SP's out there are not just fluffy clouds!

Belushi's breakdown is brain cell saving (& money)

THANKS AGAIN...Got it working too..Brill

 

[burtsbees]

What fixed it?

 

[t0mm0]

Sorry Burts bees, went for the option that Belushi suggested;

interface Serial0
frame-relay switching
ip address 192.168.2.101 255.255.255.0
encapsulation frame-relay
clockrate 128000
frame-relay map ip 192.168.2.102 220 broadcast
frame-relay intf-type dce
no frame-relay inverse-arp



interface Serial0/0
description Interface to Testpod2
ip address 192.168.2.102 255.255.255.0
encapsulation frame-relay
frame-relay map ip 192.168.2.101 220 broadcast
no frame-relay inverse-arp
end
