frame switch…

what a pain in the ass… 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…
