So show IP interface brief.
Various interfaces are found, we need to no shut VLAN 1 on the switch, so interface, VLAN 1no shut,
we can see that VLAN 1 has come up and a new EIGRP neighbour relationship has been formed.
So show IP interface brief,
we can see that both the loopback and a VLAN 1 are up.
So interfaces are up
but I mustn't forget the most important piece, which is to set the secret password of the switch, so
enable secret Cisco, save the configuration.
So again, show IP interface brief,
interfaces are up.
Show run shows us the secret password, if I exit out of the switch and type enable, I can log back
in with the password of Cisco.
So this looks good.
I'm going to save the device configuration now, show IP route shows us various routes and we should
be able to ping the loopback of router 1 and the loopback of router 2 which we can. So again, show IP
route, shows us the routing table
and we can ping the loopbacks of the routers.
Now, on router 1, router 1 was rebooted when we reset the power of the switch, but I can log
in and I should be able to ping the switch, which I can same on router 2.
Should be able to ping the loopback of the switch, which I can. So at this point I've reset passwords,
I've restored device configurations and proven that we can ping the loopbacks of old devices.
Now, we need to verify that when devices are reloaded, configurations are restored using the new passwords.
So again, I'll save the configuration of the switch to make sure show startup-
config shows us the switch configuration.
So I'll power cycle the devices, devices are rebooted, switch 1 is booting up.
So here's router,
so is router 2.
So let's see if the devices boot and apply
their configurations correctly
and allow us to log in.
So here's switch 1 type enable password is Cisco, I can log into the switch, show IP interface brief shows me the
various interfaces that are up.
We need to wait for spanning tree to converge.
Here's router 1 enable can log in with the password of Cisco, that looks good.
Neighbor relationships
are being formed.
Router 2 enable password of Cisco, that looks good, show IP Interface Brief shows me that interfaces are
up.
Can we ping router 1?
Yes, we can, can we ping the switch?
Yes, we can, on the switch
can we ping the loopback of router 1?
Yes, we can, loopback of router 2? Yes, we can and our local loopback.
So I've successfully verified that when devices are reloaded, configurations are restored using the
new passwords of Cisco.
So we've completed that lab.
Make sure that you know how to restore passwords for the CCNA exam.
So how did you do with this lab?
Were you able to complete the lab and successfully restore passwords? Make sure that, you know how passwords
work and how password recovery works for the CCNA exam.
