So let's power on the P.C. and open up a console and see if it now receives an IP address.
So I have config eith zero.
Notice the difference.
It's now received a global IP address.
2001 Cole on 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 wire shock
there are the right advertisements we saw previously and scrolling down we see a rather solicitation
message to f f 0 2.
Colon colon 2.
From a host with a MAC address ending in 6 a 4 b center this year 6 a 4 B going to all routers on the
local segment.
There's the MAC address which is the layer to MAC address for IP version 6 multi costs.
In this case for f f 0 2 colon colon 2 and we can see that the multicast was sent from this host.
There is the link local address as shown here in y shock so the host is sending a rider solicitation
to all riders in the local segment and the rider replies back to all hosts on the local segment.
There is the IP version 6 multicast address from the broader to the IP version 6 multicast layer to
address sources the rider destination is FFA 0 2 Collin Collin 1 it's a run advertisement and the rider
is once again telling the host it's local MAC address there is the link layer address.
Here's the empty you man here is the IP version 6 prefects.
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 Rada so let's call this 2001 on 0 1 0 1 so at an address
like this and let's see if the Rada advertises that to the host.
Notice there's the advertisement sent to all hosts on the local segment and back on the P.C. and back
on the P.C. I have conflict eith zero.
What we should notice is it after a while we'll learn that network and there you go.
After a while the host has learnt that a new address.
So can the host ping and the router show run interface gigabit to 0 0 shows us the 2 IP version 6 addresses
on the router so ping 2001 face colon colon 1 Notice I'm using the wrong protocol I need to use ping
6 and that ping now succeeds so ping 6 2001 there 1 0 1.
Colon colon 1 that ping also works on the right or we could do a debug IP vs 6 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 6 address.
I have config eith 0 shows us that IP address as configured on the P.C. notice it ends in 6.
A 4 b the destination of the Echo request was the rudder and the rudder now sends a code reply.
There's the IP version 6.
Echo request IP version 6.
Echo reply he has a rudder advertisement sent from the local rudder to the destination.
F f 0 2 col on column 1.
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 NDP.
