Forgive me, I am a self learner. Now studying basic frame relay multipoint.
I have done configure hub (R1) and spoke routers (R2 and R3) but I am confuse of how to configure the frame relay router (R4) in this hub and spoke situation. Can you tell me how can I configure that Frame relay router (R4) by using this topology please.
Here is an example to get R1 talking to R2 via R4
R4#show running-config Building configuration... <output omitted> ! hostname R4 ! <output omitted> ! frame-relay switching ! interface Serial0/0 no ip address encapsulation frame-relay clockrate 64000 frame-relay intf-type dce frame-relay route 122 interface Serial0/1 221 ! interface Serial0/1 no ip address encapsulation frame-relay clockrate 64000 frame-relay intf-type dce frame-relay route 221 interface Serial0/0 122
Validation command: show frame-relay route
Parameters such as clock rate can be changed.
Hope this helps.
R1 interface configuration is this:
R1(config)#interface Serial0/0 R1(config-if)#encapsulation frame-relay R1(config-if)#interface serial0/0.123 multipoint R1(config-if)#ip address 10.54.123.1 255.255.255.248 R1(config-if)#frame map ip 10.54.123.2 122 broadcast R1(config-if)#frame map ip 10.54.123.3 123 broadcast R1(config-subif)#end
Is there any missing information in the topology?
not that I can think of, you need to put an additional route in on your frame-relay switch which is R4 for the other mapping.
