Horizontal split-by-the-art-VPN)

Topology of the test on the Kerberos split horizon Node

The network type we tested is frame Relay HUB-SPOKE. R1 establishes frame ing with R2 and R3, R1 is the hub end, and 2 and 3 are the spoke ends respectively. R2 only establishes a ing with R1, and R3 only establishes a ing with R1.

Configure Frame Relay:

R1 Configuration:

 
 

  
  
R1 # conf t
  
  
R1 (config) # int lo 0
  
  
R1 (config-if) # ip add 1.1.1.1 255.255.255.0
  
  
R1 (config-if) # no sh
  
  
R1 (config-if) # int s0/0
  
  
R1 (config-if) # ip add 11.1.1.1 255.255.255.0
  
  
R1 (config-if) # encapsulation frame-relay
  
  
R1 (config-if) # no arp frame-relay
  
  
R1 (config-if) # no frame inverse-arp
  
  
R1 (config-if) # frame map ip 11.1.1.2 102 broadcast
  
  
R1 (config-if) # frame map ip 11.1.1.3 103 standard broadcast frame Relay configuration)
  
  
R1 (config-if) # no sh
