Subject: FRAME-RELAY ENCAPSULATION QUESTION

Hi all,

I have a question for the following scenario, let's say we have 3
routers, R1, R2, R3.

The following topology is used (Hub-Spoke) R1 is the hub, and R2 and R3
area spokes. If R3 is set with the following config:

Interface serial0/0
 encapsulation frame-relay ietf

How should I configure R2 and R1 with frame-relay map statements in
order to match the correct encapsulation for R3 ?

Should I set the following config:

R1 (HUB)
Interface serial0/0
 encapsulation frame-relay
 ip address 200.200.200.1 255.255.255.0
 frame-relay map ip 200.200.200.3 103 broadcast ietf
 frame-relay map ip 200.200.200.2 102 broadcast

R2 (SPOKE -CISCO ENCAPSULATION-)
Interface serial0/0
 encapsulation frame-relay
 ip address 200.200.200.2 255.255.255.0
 frame-relay map ip 200.200.200.1 201 broadcast
 frame-relay map ip 200.200.200.3 201 broadcast

R3 (SPOKE -IETF ENCAPSULATION-)
Interface serial0/0
 encapsulation frame-relay IETF
 ip address 200.200.200.3 255.255.255.0
 frame-relay map ip 200.200.200.1 301 broadcast
 frame-relay map ip 200.200.200.2 301 broadcast

Or should I set it up this way:

R1 (HUB)
Interface serial0/0
 encapsulation frame-relay
 ip address 200.200.200.1 255.255.255.0
 frame-relay map ip 200.200.200.3 103 broadcast ietf
 frame-relay map ip 200.200.200.2 102 broadcast

R2 (SPOKE -CISCO ENCAPSULATION-)
Interface serial0/0
 encapsulation frame-relay
 ip address 200.200.200.2 255.255.255.0
 frame-relay map ip 200.200.200.1 201 broadcast
 frame-relay map ip 200.200.200.3 201 broadcast ietf

R3 (SPOKE -IETF ENCAPSULATION-)
Interface serial0/0
 encapsulation frame-relay IETF
 ip address 200.200.200.3 255.255.255.0
 frame-relay map ip 200.200.200.1 301 broadcast
 frame-relay map ip 200.200.200.2 301 broadcast

Regards,

Luis
