These routers have just booted and don't have any configuration on them.
As an example here you can see that Rotto one is asking us to enter the initial configuration dialog
and I'm going to say no because I don't want to do that
this router is a virtual Iowas Roddy running at vaunts enterprise services version 15 dot 6.
So these routers are essentially Iowas V routers.
So first thing I'll do is configure a hostname.
Note please that if I try to enable OSPF
or rather OSPF I'm told that my PV 6 routing is not enabled.
We need to do some initial configuration on these routers before we can enable OSPF version 3.
And one of the obvious things we need to do is configure IP addresses so on the loopback I'm going to
configure an IP address like this and on gigabit 00 all configure an IP address as per the diagram such
as this and no shut the interface so to show IP not IP version 4 here interface brief.
What you'll notice is that no IP addresses have been configured on this router.
In other words no IP version 4 addresses have been configured but show IPV 6 interface brief shows us
that this interface gigabit 00 has this IP address as well as a link local IP address configured and
the same is true for the loopback address.
Again IPV six router OSPF one shows us that IP V-6 writing is not enabled on the router.
So the first thing we need to do is enable IPV six unique cost routing.
Now we can configure a routing protocol and in this example we have Joe the network mobility OSPF and
rap but we will configure always SPF with a process Id always a version 3 is once again very similar
to OSPF version 2.
So the process ID is a locally significant number on the broader note.
This message however is Version 3 IPV 6 could not pick a router ID please configure manually.
So that's because we didn't configure an IP version 4 address.
So we now within the OSPF process need to configure a router ID of a 32 bit number set to show run pipe
begin with.
If this is the OSPF version 3 configuration that weve done on the router
now at this point show IPV 6 interface brief shows that no interfaces have been added to the OSPF version
3 process.
We need to go to each individual linked face and type IPV 6 OSPF the process number in our example that's
process ID 1 we need to specify the area and the area that we putting the interface into.
So in this example the loopback interfaces being put into OSPF So the command show IP V-6 OSPF interface
brief now shows us that the loopback interface has been added to the OSPF process process ID is one
area is one to form relationships with other routers and in this case Rodda two will need to enable
SPF on gigabit 0 0 on router 1.
So IP V-6 OSPF process ID is one area that will configure is one.
So now show IPV 6 OSPF interface brief shows that both of those interfaces are added to APF.
A lot of the commands that you've used previously still apply here so show IPV six protocols instead
of show IP protocols shows us that we are running OSPF with this Rodda ID with these interfaces added
to OSPF and a single normal area of the protocols are also listed here like a neighbor Discovery show
IPV 6 SPF.
Neva no neighbors at the moment of IPV six route
so theres the command.
We have no OSPF rats in the running table because we haven't formed a neighbor relationship with any
other Rodda show.
IP The six SPF.
Lot of options here.
But let's choose
database.
We have a very similar database output to what we have in OSPF version 2.
In other words IP version 4.
So as an example we have one router in the database at the moment.
There are other Elisei types which we won't talk about as part of the CCMA.
But notice Elisei type 8 is also listed in the database show IPV 6 OSPF enter.
So there's the command.
We're running a version 3 OSPF process with number one Rodda ID is 1.
A lot of other information shown here including the areas configured.
In this case it's Area 1 and 2 interfaces are being put into that area.
The SPF algorithm has run once show IP V-6 OSPF interface instead of brief.
So here's the command and notice on the gigabit interface the link local addresses this.
It's a broadcast network type.
In other words a election will take place rodder one is the designated router on the interface and it
has this Rodda ID which we configured manually.
Notice that time is haloed time is 10 seconds.
Date interval is 40 seconds.
There is no backup.
A router on the interface.
So once again show IPV six SPF neighbor shows us that there are no neighbor relationships formed on
this network.
So let's configure the other routers and form neighbor relationships and exchange routes between the
routers.
