TOPOLOGIA



Asi debemos configurar el switch FRAME-RELAY




Configuracion R1

hostname R1
!
interface Loopback0
ip address 192.168.1.3 255.255.255.0
!
interface Serial1/0
ip address 192.168.192.1 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
!
router ospf 1
log-adjacency-changes
network 192.168.1.0 0.0.0.255 area 0
network 192.168.192.0 0.0.0.255 area 0

Configuracion R2

hostname R2
!
interface Loopback0
ip address 192.168.200.1 255.255.255.0
!
interface Serial1/0
ip address 192.168.192.2 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
!
router ospf 1
log-adjacency-changes
network 192.168.200.0 0.0.0.255 area 0
network 192.168.192.0 0.0.0.255 area 0

Configuracion R3

hostname R3
!
interface Loopback0
ip address 192.168.232.1 255.255.255.0
!
interface Serial1/0
ip address 192.168.192.4 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
!
router ospf 1
log-adjacency-changes
network 192.168.232.0 0.0.0.255 area 0
network 192.168.192.0 0.0.0.255 area 0
__________________________________________________________________________
Otra manera de hacerlo es configurando un Router como switch frame-relay



De esta manera fue configurado dejo un vistaso al running-config

hostname Switch-RF
!
frame-relay switching
!
interface Serial1/0
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 102 interface Serial1/1 201
frame-relay route 103 interface Serial1/2 301
!
interface Serial1/1
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 201 interface Serial1/0 102
!
interface Serial1/2
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 301 interface Serial1/0 10

***El resto de los Router's (R1,R2 y R3) quedan igual a la configuracion anterior, o si queremos agregamos los mapas de frame-relay manualmente de la siguiente manera en cada una de las interfaces de los Router's:

R1
interface Serial1/0
ip address 192.168.192.1 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
frame-relay map ip 192.168.192.2 102 broadcast
frame-relay map ip 192.168.192.4 103 broadcast

R2
interface Serial1/0
ip address 192.168.192.2 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
frame-relay map ip 192.168.192.1 201 broadcast

R3
interface Serial1/0
ip address 192.168.192.4 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
serial restart-delay 0
frame-relay map ip 192.168.192.1 301 broadcast
