  1. many thanks for the article; however the spoke-spoke mappings at the end of the article are not correct and we need a new DLCI mapping other than the one already used

    If I use the mappings defined here, when pinging from Spoke1-Spoke2 (and vice verca) I get UUUUU. Changing the mappings to 2:221-3:321 on the switch and the spoke configs solved the problem

    Spoke1 - frame-relay map ip 221
    Spoke 2 - frame-relay map ip 321

  2. Hi Rene,

    If we disable the split-horizon so how you can solve the counting to infinity problem ?


  3. Hello Rene,

    If a pvc has been created between hub-spoke1 and hub-spoke2, how is the traffic from spoke2 to spoke1 going to get to spoke1 by just creating mappings between spoke2 and spoke1?? Should the route table for spoke2 point to as the route to reach on spoke1 via the pvc since this is the next hop in its path? Then should Hub route the traffic via its pvc to reach on spoke1?

    If not, how does the Frame Relay switch know to pass data between spoke2 and spoke1 if a pvc has not been created between a dlci on spoke2 and dlci on spoke1?




  4. Hi,

    Here is my configuration

    interface Serial2/2
    ip address
    encapsulation frame-relay
    serial restart-delay 0


    interface Serial2/1
     ip address
     encapsulation frame-relay
     serial restart-delay 0



    interface Serial2/3
     ip address
     encapsulation frame-relay
     serial restart-delay 0

    interface Serial2/1
    description R1
    no ip address
    encapsulation frame-relay
    serial restart-delay 0
    frame-relay intf-type dce

  5. Hello,

    I configured this in GNS3 using just the physical interfaces, no subinterfaces, and static frame-relay mappings between the hub and spokes, and between each spoke. However, when RIP is enabled, Spoke2 has Spoke1’s loopback in its routing table even though I haven’t disabled split-horizon on the Hub router. I don’t see any default ‘no ip split-horizon’ in the Hub router’s configuration. Is this normal? I would expect it not to be advertised to Spoke2 because of split-horizon.

    Thank you for any help.
