R2中的配置:
interface Tunnel0
no ip address
tunnel source Ethernet0
tunnel destination 172.16.0.2
!
interface Ethernet0
ip address 172.16.0.5 255.255.255.0
!
interface Serial0
no ip address
encapsulation frame-relay
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 301 interface Tunnel0 100
frame-relay route 302 interface Tunnel0 101
R5的配置:
interface Tunnel0
no ip address
tunnel source Ethernet0
tunnel destination 172.16.0.2
!
interface Ethernet0
ip address 172.16.0.5 255.255.255.0
!
interface Serial0
no ip address
encapsulation frame-relay
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 301 interface Tunnel0 100
frame-relay route 302 interface Tunnel0 101
DLCI的分配:
R4:201------->R1 ; 203---------->R3
R3:302------->R4 ; 301---------->R1
R1:103------->R3 ; 102---------->R4
注意要在全局配置模式启用fr switching。
