Hi Wei,
Back-to-back FR connection, you need to set the same DLCI number, and no
keepalive under serial interfaces.
Your configuration will works as:
interface Serial3/0
no ip address
encapsulation frame-relay
no keepalive
interface Serial3/0.1 point-to-point
ip address 1.1.1.1 255.0.0.0
clockrate 64000
frame-relay interface-dlci 403
R4-4500#
interface Serial4/0
no ip address
encapsulation frame-relay
no keepalive
interface Serial4/0.1 point-to-point
ip address 1.1.1.2 255.0.0.0
frame-relay interface-dlci 403

Subject: Frame Relay back to back
Hi:
I have following topology with Frame relay back to back:
R3-3640 ---304(dlci) ----403(dlci)----R5-4500
I have following configurations:
R3-3640#sh run int s3/0
interface Serial3/0
ip address 1.1.1.1 255.0.0.0
encapsulation frame-relay
clockrate 64000
frame-relay map ip 1.1.1.2 304 broadcast
no frame-relay inverse-arp
frame-relay intf-type dce
end
R4-4500#sh run int s4/0
interface Serial4/0
ip address 1.1.1.2 255.0.0.0
encapsulation frame-relay
frame-relay map ip 1.1.1.1 403 broadcast
no frame-relay inverse-arp
end
Questions:
1) If I don't configure intf-type dce on R3-3640, why the interface and
line protocol will be both down at two routers, do I have to configure
one
side as FR switch?
2)with above configuration, why I can not ping each other. R4-4500 "show
frame map" shows 403 pvc deleted. in show frame pvc, R4-4500 shows 304
unused. If I change 403 to 304 which is the same as 304 in R3-3640,
everything works fine. Can not I have two different DLCI in this
topology?
Is that because the switch side advertise 304 which get messed up with
static map 403 in the R4-4500?
can somebody share some thoughts here?
Thanks
Wei
