the frame-relay intf-type command is used on a frame relay switch, as part of the switch to switch config. it should not be used on a customer edge device.
if you were to enter the "frame-relay switching" commands on R1 and R3, the interfaces would come up and the routers would engage in frame-relay switch signaling. You probably want to remove the frame-relay intf-type commands from R1 and R3, making them customer edge devices, at which point they will communicate with R2 ""tigers zheng"" wrote in message news:[EMAIL PROTECTED] > I have a question about frame-relay!Please tell me why it happened? > the topolofy :r1(s0)---(s0/0)r2(s0/1)---(s0/0)r3 > r1:2511,r2:2620,r3:2621 > > the configuration: > r1: > interface s0 > ip address 10.10.10.1 255.255.255.0 > encapsulation frame-relay > frame-relay lmi-type ansi > frame-relay intf-type dte > frame-relay interface-dlci 100 > ! > r3: > interface s0/0 > ip address 10.10.10.2 255.255.255.0 > encapsulation frame-relay > frame-relay lmi-type ansi > frame-relay intf-type dte > frame-relay interface-dlci 101 > ! > r2: > frame-relay switching > int s0/0 > no ip address > encapsulation frame-relay > clockrate 64000 > frame-relay route 100 interface s0/1 101 > frame-relay lmi-type ansi > frame-relay intf-type dce > ! > int s0/1 > no ip address > encapsulation frame-relay > clockrate 128000 > frame-relay route 101 interface s0/0 100 > frame-relay lmi-type ansi > frame-relay intf-type dce > ! > But the serial of all of the router is shutdown,line protocol is also down! > I want to know what happen! > Thanks very much!
