So let's power on the PC.
And open up a console and see if it now receives an IP address.
So if config is zero.
Notice the difference.
It's now received a global IP address 2001 colon face the network portion is that.
Followed by some zeros.
This is the host portion, which you'll notice is the same as the link local host portion and is based
on the MAC address of the host.
So back in Wireshark.
They are the advertisements we saw previously.
And scrolling down, we see a rather solicitation message to f02 colon.
Colon two from a host with a mac address ending in six A for B so notice.
Yes six A4 be going to.
All routers on the local segment.
There's the Mac address, which is the layer to Mac address for IP version six multi costs in this case
for f02.
Colin.
Colin two.
And we can see that the multicast was sent from this host.
There is the link local address as shown here in Wireshark.
So the host is sending a router solicitation to all routers in the local segment and the router replies
back to all hosts on the local segment.
There is the IP version six multicast address from the router to the IP version six multicast.
Layer two address.
Sources.
The rudder destination is f02 Colin.
Colin one It's a rudder.
Advertisement And the rudder is once again.
Telling the host its local Mac address.
There's the link layer dress.
Here's the empty view and here is the IP version six prefix.
So the host has dynamically learnt this address.
So that was an example of Slack.
What I'll do now is add another address on the rudder.
So let's call this 2001 colon 0101.
So at an address.
Like this.
And let's see if the writer advertises that to the host.
Notice there's the advertisement sent to all hosts on the local segment.
And back on the PC and back on the pc.
I have config eith zero.
What we should notice is it after a while will learn that network.
And there you go.
After a while, the host has learnt that new address so can to the host ping.
The router show.
Run.
Interface gigabit.
Zero zero.
Shows us the two IP version six addresses on the router.
So ping 2001 face colon.
Colon one notice I'm using the wrong protocol.
I need to use ping six.
And that ping now succeeds.
So ping six 2001 0101.
Colin.
Colin one.
That ping also works.
On the rider.
We could do a debug.
IPV six ICMP and I can do the ping to face once again and notice we see that output on the router.
Echo request was received from a source with this IP version six address if config if zero shows us
that IP address as configured on the PC.
Notice it ends in six A for B.
The destination of the echo request was the rudder, and the rudder now sends a reply.
There's the IP version six echo request IP version six echo reply.
Here's a rata advertisement sent from the local rudder to the destination.
EF zero two Colin.
Colin one all nodes on the segment.
So that was a demonstration of how slack and rudder advertisements and rudder solicitation messages
can be used to automatically allocate networks to hosts.
This is once again using the Neighbor Discovery Protocol or MDP.
