Obs: para o cisco3 usar o comando 'write'
cisco3#
cisco3#write
#####[OK]

SHOW RUNNING -CONFIG
Este comando é utilizado para verificar a configuração do roteador.
Observar se a interface está UP/DOWN, quais os IPs de cada interface
e que redes são anunciadas por RIP e quais são anunciadas por OSPF.

Neste ítem serão mostrados dois comandos que são fundamentais para
que possamos tirar nossas conclusões.
São eles:show ip route e traceroute.
O primeiro nos mostra por qual interface e por qual protocolo o roteador
aprende as outras redes, já o segundo nos mostra os roteadores percorridos até o endereço de destino.

Verificamos que o roteador cisco2 aprende as outras redes por OSPF
através de suas interfaces Serial1, via 200.20.4.2 (Serial1 cisco3)
e Ethernet0 via 200.20.94.81 (Ethernet0 cisco1).
É importante ressaltar que as redes 192.80.209.0, 200.20.6.0
