Frame-relay Serial interface up down

NaveenJakhmola

Level 1

Hello Everyone,

This is my First ever post.

Recently i was doing a lab for PBR using some serial interface. below is the topologypbr-topology21.png

 

But i am stuck as the between R2 and R3 is not coming up. i am using frame-relay between them.

P.S :  i just have basic understanding of frame-relay

 

below is the run config 

R3 #

 

interface Serial0/0

Hello,

 

I cannot tell if you have a frame relay switch in your topology. In any case, you need one. Check the video below:

Hello,

 

is this a simulator, or are you using real equipment ? In the latter case, typically one router is configured as DCE (frame-relay intf-type dce) and provides the clock. Also, try and disable keepalives (no keepalive interface command)...

Hi Georg,

I am using a simulator

Which one ?

Hi Georg,

 

Thanks for your prompt Response.

I am using GNS3 2.1.5 and IOS c3725-adventerprisek9-mz.124-15.T14.bin
