frame-relay switching

Hi guys.

Do thse commands look correct for configuring frame relay
Router B is a 2500 series router configured as a frame-relay switch.
cisco say it needs the Ip unnumbered loopback command but other sources say the no ip address command is needed.

any help would be great

router A
Int s 0
Encapsulation frame-relay
Ip address 199.6.13 .3 255.255.255.0
No shut

router C
Int s 1
Encapsulation frame-relay
Ip address 199.6.13 .2 255.255.255.0
No shut

router B
Frame-relay switching
Int s 0
Ip unnumbered loopback 0
Encapsulation frame-relay
Clack rate 64000
Frame-relay intf-type dce
Frame-relay route 21 interface serial 1 20
No shut
Int s 0
Ip unnumbered loopback 1
Encapsulation frame-relay
Clack rate 64000
Frame-relay intf-type dce
Frame-relay route 20 interface serial 0 21
No shut

any help would be great

"clack" should be "clock".

Happy frame switching!

You do not need the "ip unnumbered" command onthe frame switch. they are acting as a L2 interface so the L3 configuration is not needed.
