Ahora que
hemos anunciado todas las redes que tiene conectado directamente cada Router,
podemos responderestas preguntas:
¿Se puede
hacer un ping de la PC0 a la PC1? Si
¿Se puede
hacer un ping de la PC1 a la PC2? Si
¿Se puede
hacer un ping de la PC2 a la PC0? Si
¿Se puede
hacer un ping de la PC2 a la PC1? Si
Si a
todas las preguntas respondieron “Si”, ¿a que se debe que exista ahora una
conectividad entre todas las redes del diagrama? A que los router se
pueden ver entre si con sus respectivas lan lo cual indica una configuracion
correcta de OSPF
