Frame Relay Static Mapping


Jack and Emma are using an old frame-relay switch to connect their routers. Unfortunately they are unable to get any connection. Think you can help them out?


  • All IP addresses have been preconfigured for you.
  • Disable frame relay inverse ARP.
  • Configure frame relay mappings so the routers can ping each other.
  • Frame relay should support broadcast emulation.

It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNA.

Would you like to be a master of networking too? In a short time without having to read 900 page books or google the answers to your questions and browsing through forums?

I collected all my knowledge and created a single ebook for you that has everything you need to know to become a master of CCNA.

You will learn all the secrets about routers, frame-relay, inverse ARP and more.

Does this sound interesting to you? Take a look here and let me show you how to Master CCNA!

  1. I can ping each router. Here is my configuration . Anyone is welcome to let me know if I am missing something


    interface Serial0/0
    ip address
    encapsulation frame-relay
    serial restart-delay 0
    frame-relay map ip 102 broadcast
    no frame-relay inverse-arp


    interface Serial0/0
    ip address
    encapsulation frame-relay
    serial restart-delay 0
    frame-relay map ip 201 broadcast
    no frame-relay inverse-arp

  2. Hi Jawed,

    That’s it…disable Inverse ARP and create those frame-relay maps. Adding the broadcast keyword is a good idea if you want to run any protocols using broadcast or multicast over your frame-relay network.
