    frame switch…

     

    what a pain in the ***… been about a year since i built one… sometimes there’s just too much bgp…

    frameswitch

    here’s a template…

     

    r3fr#sh run

    hostname r3fr
    !
    frame-relay switching
    !
    interface Serial1/0
    no ip address
    encapsulation frame-relay IETF
    clockrate 64000
    frame-relay lmi-type cisco
    frame-relay intf-type dce
    frame-relay route 301 interface Serial1/1 103
    !
    interface Serial1/1
    no ip address
    encapsulation frame-relay IETF
    clockrate 128000
    frame-relay lmi-type cisco
    frame-relay intf-type dce
    frame-relay route 102 interface Serial1/2 201
    frame-relay route 103 interface Serial1/0 301
    !
    interface Serial1/2
    no ip address
    encapsulation frame-relay IETF
    clockrate 64000
    frame-relay lmi-type cisco
    frame-relay intf-type dce
    frame-relay route 201 interface Serial1/1 102

    then set up the interfaces on the various routers…
