R2 tiene una ruta por defecto configurada hacia R3, entonces hay que utilizar el comando default-information originate en la
configuración para trasferir esta ruta al protocolo rip.

Explicaciones de algunos comandos:
• Al protocolo RIP hay que transferirle las rutas OSPF, esto se hace con el comando redistribute ospf 1, al que hay que
indicarle una métrica y algunos datos mas.
•
Por el mismo motivo al protocolo OSPF hay que transferirle las rutas RIP con el comando redistribute ospf 1, al que hay
que indicarle una métrica (en este caso 65) y algunos datos mas.
•
Y por ultimo en la Red se transfiere una ruta por defecto en RIP (la generada en R2) que también hay que trasferirsela al
protocolo OSPF con el comando default-information originate (si no lo hacemos no hay comunicación entre el Sr1 y
PC3).
•
Como hay un enlace troncal con el Switch por el que van 2 VLAN hay que configurar Subinterfaces en el puerto Fa0/0
Configuración Switch (partiendo de Switch#):
conf t
hostname S1
enable secret class
banner motd &!!!AUTHORIZED ACCESS ONLY!!!&
line console 0
password cisco

exit
line vty 0 4
password cisco
login
exit
interface fa1/1
switchport access vlan 10
interface fa2/1
switchport access vlan 20
interface fa0/1
switchport mode trunk
no shutdown
exit
exit
copy running-config startup-config
En el Switch se crean 2 VLAN una para el PC1 y otra para el PC2 y el enlace troncal con el Router R4.
