Frame Relay Hub-Spoke without Mapping between Spoke

This is example topology hub-spoke use frame-relay, but between spoke there isn't mapping.

      -102---201-- R2
R1 --|
      -103---301-- R3

R1 hub
ip add 192.168.0.1 255.255.255.0
frame map ip 192.168.0.2 102 broadcast
frame map ip 192.168.0.3 103 broadcast

R2 spoke
ip add 192.168.0.2 255.255.255.0
frame map ip 192.168.0.1 201 broadcast

R3 spoke
ip add 192.168.0.3 255.255.255.0
frame map ip 192.168.0.1 301 broadcast

Between spoke never be communication, but we can test connectivity between spoke without add mapping.

R2(config-if)#do ping i  
Target IP address: 192.168.0.3
Repeat count [5]: 
Datagram size [100]: 
Timeout in seconds [2]: 
Extended commands [n]: y
Source address or interface: 
Type of service [0]: 
Set DF bit in IP header? [no]: 
Validate reply data? [no]: 
Data pattern [0xABCD]:

Sweep range of sizes [n]: 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.3, timeout is 2 seconds:
