Video para instalar un switch capa 3 en gns3
Montaje
Realizamos el siguiente montaje:
En el switch cambiamos la configuración del slot.
Configuración del Router
Configuramos la interfaz f0/0 en el router
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address dhcp
R1(config-if)#no shutdown
R1(config-if)#e
*Jan 18 13:17:47.199: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
*Jan 18 13:17:48.199: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R1(config-if)#exit
R1(config)#exit
R1#
*Jan 18 13:17:55.183: %SYS-5-CONFIG_I: Configured from console by console
R1#ping 8.8.8.8
*Jan 18 13:18:02.059: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0/0 assigned DHCP address 192.168.122.164,
mask 255.255.255.0, hostname R1
Esperamos un poco a que el router coja una ip (en mi caso, 192.168.122.164)
R1#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/20/36 ms
R1#
Succes rate => Conexión a internet correcta.
Vemos la configuración de ips en el router.
R1#sh ip int br

Configuramos la interfaz f1/0 en el router
Activamos el puerto f1/0 y creamos las 3 subinterfaces para las vlans.
R1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. R1(config)#interface f1/0 R1(config-if)#no shutdown R1(config-if)#exit R1(config)# *Jan 18 13:22:41.867: %LINK-3-UPDOWN: Interface FastEthernet1/0, changed state to up *Jan 18 13:22:42.867: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0, changed state to up R1(config)#interface f1/0.10 R1(config-subif)#encapsulation dot1Q 10 R1(config-subif)#ip address 192.168.10.1 255.255.255.0 R1(config-subif)#exit R1(config)#interface f1/0.20 R1(config-subif)#encapsulation dot1Q 20 R1(config-subif)#ip address 192.168.20.1 255.255.255.0 R1(config-subif)#exit R1(config)#interface f1/0.30 R1(config-subif)#encapsulation dot1Q 30 R1(config-subif)#ip address 192.168.30.1 255.255.255.0 R1(config-subif)#exit R1(config)#
