All right guys.
That's the last time spanning three configuration lab.
Welcome.
We have anthropology.
We have four suites connected to each other and in the first step we need to create the topology abo
and that are mine the root bridge and the question says mean that spanned three more will be rapid.
PTSD alright.
Second fourth one of the none group operates to be a root bridge by changing the priority while you
are right and the last step is force.
One of the number root breaks to be a root bridge.
But don't change the priority value.
Okay let's go ahead with the first step.
What I'm going to do is I will configure spanning three month rapid periods the and I'll check which
is my route bridge
okay call there spanning three most rapid PTSD is the whole configuration but
if I use a question mark I can see that I can also use the previous t to indifferent chairs of tweets
and different aisles versions can support different types of SDP but in this question is saying need
that to configure rapid pace the end my choices is supporting this so I'm using rapid PBS I'm going
to make the same configuration on switch to
three
and the
switch for
all right I changed my configuration and I'm using grep at PBS to right now and now it's time to check
who is my root branch I want to start with switch three and take a look at efforts my route bridge on
that two way of flying the spring tree I'm using shore spanning three command Oh my God I'm so lucky
as you can see that I've found the route bridge at my first try so how I got that because when I type
shows spanning three I's so that this bridge is the route output if we check the another switch for
example switch for oh is not typing okay start paying now
and if you're on the road show spanning three command as you can see that we don't see anything that
is saying this where is the route so all right step one accomplished let's take a look to this second
step force one of the non route brakes to be a road bridge by changing the priority value
as you can see that different priority value is thirty two thousand seven hundred and sixty eight.
So I'm going to make the switch port of switch for as my road rage now by changing the prior to Lee
County
spanning three
four wheeler man.
I'm gonna set the priority of this switch to a lower volume than
my default volume but please pay attention that bridge per t in increments of four thousand and ninety
six.
Warning so it's okay that I can use for 2010 ninety six because that's lower from my default value and
lowering the priority means that I'm making I'm forcing that switch to be the route.
Okay
I had to wait for a few seconds
and that's to ensure spending to recommend as you consider from the output.
This time
switch 4 is my route bridge switch one and switch three was the route bridge before
as you can see that but now it's not true anymore
okay.
Pretty cool and let's get into the last step the last step of the question is saying that force one
of the noun root breads to be a rope root bridge but don't change the priority value.
Let's make this switch one route bridge
because of the question saying me that don't change the priority really.
I just have one option to make this guy the route.
All right spanning three Willem van and question mark as you can see that I can see my option here.
Route
rail on my route.
Question mark again I can set the primary route or second the route but I'm going to set the primary
route.
All right when I type the show spanning three now this time I should see that.
So which one is my route bridge so let's hit the enter enter and yes I can easily see that this bridge
I mean switch one is the route Bridge right now as you can see that pretty straight forward and so easy
to configure the SDP and we can have a few options to change the route bridge and we completed the three
steps through in the configuration lap and thanks for waiving.
