Frame Relay Routing...

jgaude
Level 1
Level 1

Hello,

I'm trying to route Frame Relay in a test lab and have not been successful yet. I've got two 7206 routers, with IOS 12.0, and E1 serial cards. I've got the E1's cross connected with an RJ45 cable... link lights are good. I've setup each E1 as a frame relay with dlci 16.... sh frame-relay pvc looks good. I've alos got a PC on each router hanging off the Eth0 port.... My goal is to have each PC able to ping the other through the routers. So far on each side, the PC can ping it's Eth interface and the Serial5/0:0 interface, but no further....

Here are a copy of my configs for each router... Can someone tell me where I'm going wrong?

Thanks,

...Joe

Gateway of last resort is 192.168.34.0 to network 0.0.0.0

156.23.0.0/24 is subnetted, 1 subnets

C 156.23.150.0 is directly connected, Ethernet1/1

C 192.168.34.0/24 is directly connected, Serial5/0:0

S* 0.0.0.0/0 [1/0] via 192.168.34.0

This is the second routers config:

Hello,

you only need to enable frame-relay switching on one of the routers. I would take it out of the config of the second router. In addition, you need to add the ´clock rate´ command to the interface configuration of your first router:

interface Serial5/0:0

description ppp channel 5

ip address 192.168.34.1 255.255.255.0

no ip directed-broadcast

encapsulation frame-relay IETF

ip mroute-cache

no fair-queue

--> clock rate 64000

frame-relay interface-dlci 16

frame-relay lmi-type ansi

frame-relay intf-type dce

Can you try and see if that helps ?

Regards,

Georg

Hi Georg,

I'll go over and try the clock rate and remove the frame-relay switching off the second router and report back.

Thanks!!!

...Joe

Hi Georg,

Nope, the clock rate and removal of the second frame-relay switching did not help...

Should i have both router interfaces set to dlci 16? Or should they be different?

Do I need to run rip? Or maybe specify a neighbor?

I'm really lost as to why this doesn't work....

Is there some show commands that would be helpful in finding out where I've gone wrong?

Thanks,

...Joe

From the config of the first router:

interface Serial5/0:0

description ppp channel 5

ip address 192.168.34.1 255.255.255.0

From the config of the second router:

interface Serial5/0:0

description ppp channel 5

ip address 192.168.32.2 255.255.255.0

If this is in fact your back to back connection then put them into the same network and subnet.
