>> Hello there Cybrarians and welcome back
00:00
to the Linux plus course here at Cybrary.
00:00
I'm your instructor Rob Goelz and in today's lesson,
00:00
we're going to be discussing network bridging.
00:00
Upon completion of this lesson,
00:00
you'll be able to understand the use of
00:00
the brctl command. Network bridging.
00:00
A Linux system connected to
00:00
two separate networks can be configured as a bridge.
00:00
It's just a way to connect
00:00
the separate networks together into one network.
00:00
The command used to do this is the brctl command.
00:00
Bridge CTL, bridge control, brctl command.
00:00
Now the brctl command can create
00:00
a bridge and you're going to want to
00:00
do this in a few steps.
00:00
The first thing that you need to do
00:00
is add the bridge using
00:00
brctl addbr, and then you give it a bridge name.
00:00
Then from there you can add
00:00
interfaces like the interfaces we saw in
00:00
the previous lessons using brctl addif.
00:00
Brctl addif, for example,
00:00
amp0s3 like we saw previously.
00:00
Now the bridge can be taken down just as easily.
00:00
We can do a bridge delete.
00:00
We say bridge delete interface,
00:00
brctl delif and then the interface name and
00:00
then once you've removed all the interfaces
00:00
on either side of the bridge,
00:00
you delete the bridge itself,
00:00
brctl delbr, and the bridge name.
00:00
If you want to show bridges on a Linux system,
00:00
you use the brctl show command and if you
00:00
want to get information about a very specific bridge,
00:00
you type brctl showbr,
00:00
and then provide the bridge name.
00:00
We've reached the end of this lesson
00:00
and in today's lesson,
00:00
we covered network bridging and
00:00
the use of the brctl command.
00:00
Thank you so much and I look forward to
00:00
seeing you in the next lesson.
