Level 1

I am trying to set a frame relay lab so I can create the cloud and proceed with my BCSI exam training. I have

2 x 2610 with 2 serial interfaces

1 x 2510 w/ 2 serial interfaces

2 x 2900 XL switches

Please help

Thanks

Hope to help

Giuseppe ,

I changed my config so many times that I am lost right now.

can you pls help w/ full config for r1 , r2 and r3 ..can do it anymore.. I just get more confuse.

Thanks

here is my current config

r1

interface Serial0/0

ip address 192.168.10.5 255.255.255.252

encapsulation frame-relay

no keepalive

serial restart-delay 0

frame-relay interface-dlci 103

r3

interface Serial0

ip address 192.168.10.6 255.255.255.252

encapsulation frame-relay

no keepalive

no fair-queue

r2

interface Serial0/0

ip address 192.168.10.10 255.255.255.252

I forgot to include encapsulation frame-relay in my previous post, my apologies - I was doing the commands from the top of my head.

Can you please go back to that config and include that command as well on R3?

It should work and R3 will become your FR Switch device.

Using R3 as the FR Switch, and not being too sure of what the author was actually trying to do, here are my working configs below. From R1 I can ping R3 and vica versa. I used Cisco NetLabs for this fyi, so I couldnt change the cables, hence the DCE config on the FR switch and the clockrate on the R2 sw. And my ports changed alittle bit. I forgot one thing, why from R1 can I not ping R1? Would I need a fr map statement?

R3#

In order to ping the serial interface of R1 from R1, you need a frame-relay map statement pointing to the remote DLCI or you can use subinterfaces.

When pinging the local serial, the packet actually tries to exit the interface and since there isn't any mapping for that IP, it fails.

Got it, thank you.

ok , Thank you all for your help. got the frame-relay up and running,
