LINUX: Understanding Bridging Interfaces in Linux

119 ratings | 30447 views
More videos like this on http://www.theurbanpenguin.com : Bridging is not new, but many admins may have only studied this in class and not used the technology until they now see it in Virtualization hosts like XEN or VMWare. Bridges connect network segments together and we will see this on my SUSE lab machines

do both networks have to exist on the same subnet? or does bridging also work if one network is 192.168 and one is 10.0?

i've been studying for the RHCSA exam lately and every once in a while i come across a topic i'd like more explanation on. and every time i look for a topic here on youtube looking for a video tutorial, i see you've made a video on it... and you're usually at the top of my search results. i gotta congratulate you on the sheer variety of topics and depth of your videos. you're becoming my go-to resource for anything linux. keep them coming!

Good stuff. I was confused but seeing the concrete example really helped. Going to set up bridging on my multi-nic test box to play with it.

@kdpawson I agree it's a great video. I hope I can clarify the difference between bridging and bonding. According to linuxfoundation, a bridge transparently relays traffic between network interfaces. As its name implies, it just passes packets from one interface to the other, transparently. Bonding is used to make multiple interfaces behave as one, it's usually done for redundancy reasons. HTH

@theurbanpenguin Oops sorry I missed that one, will check it out now, thanks.

Great Video! One thing I find a little confusing, is that some distros use the term bonding and bridging. For example my understanding is that Debian/CentOS term bonding is for configuring 2 or more NICs to act as an aggregate for either redundancy/aggregate - just like NIC Teaming. I don't work with SUSE so I'm not sure if it's the same, but certainly this video is the same bridging method that I understand with other distros. Perhaps you could clarify this and make a video on network bonding?

a hub with Linux Power - excellent to see how 2 devices communicate when br0 is on eth0 and eth1 :) nice video sir
