Multi Protocol Label Switching (MPLS) Explained

[sandoval7]

your artwork/penmanship is atrocious, but the information so very helpful...thanks. Keep it up (the information, of course)

[johndoe1971]

You are the best thanks for another fine video sir!

[alarmus90]

make subtitles pls ^(

[paulspragg]

Succint, concise and clear - much appreciated. Thanks, Paul

i've got two questions , is this a layer 2 VPN ? i mean does the network in Atalanta is the same as the network in Miami ?

and number 2 : i assume this vpn works only on the "area" of the service provider ? what if the the sites are located on very distanced areas ?

[RayGunOfDeath]

The best rule of thumb is unless you have worked for a carrier in a technical capacity, it is best to abstain from commenting on carrier networks. They are NOT the same as enterprise. Anybody who thinks so ONLY knows the enterprise.

[RayGunOfDeath]

Actually a carriers network is a lot more than routers and switches. That is a common misconception and absolutely incorrect.

[Jisamaniac]

That was very helpful. Thank you.

[mrbobweaver]

Video #2 that I have seen of yours Just as good Use that white board brother !!!!

[roberto44699]

MPLS - Multiple Packe Loss Service. I use 1-VoIP for SIP peering.

[dkamle234]

crystal clear thoughts, thank you !- & keep those videos coming pls

[vijay85cisco]

all said...what else to tell ...

small video but it is a good one thanks prof.

[ybgururaj]

Hi Mike as usuall the videos are crisp and clear. I wanted to know how does VPN with in a MPLS network work.

[michaeljcavanaugh]

@ybgururaj By VPN I assume you mean IPSec? If so, yes. MPLS is a tunnel / VPN at layer 2, so it switches all traffic to the other side of the tunnel / VPN based on the layer 2 label. It doe not care if layer 3 and above are encrypted.

[adamfitch2010]

Thanks a lot for such a wonderful tutorial.

[arashpa80]

thanks so much. this video helps me alot to understand the MPLS for my EXAM.

many thanks again

[THAIGERTROY]

GREAT EXPLANATION!! Well done!

[heroics03]

Thanks for the video!

[amsimann]

who the f**k disliked it...great explaination

[chriskc04]

Thanks for taking the time to make this. It was very well explained.

[sajisunnyc]

forgot to add to my previous post. " this video clip is fantastic".. thanks for making it simpler to understand.

[sajisunnyc]

one doubt, you said all branch office are connected over the MPLS cloud to communicate to each other. how secure or reliable is the service provider who runs MPLS. If something happens to the service providers cloud backbone , wont it it affect all the connections globally.

[michaeljcavanaugh]

@sajisunnyc The security / reliability will depend on the service provider, but as a general rule there is a great deal of redundancy in a service provider's network to account for that very situation.

[172Break]

Well explained. I was watching the video thinking that your name was familiar. When I checked my book collection I found out why. I bought your QoS book many years ago!

[michaeljcavanaugh]

@172Break Thanks! Hope the book helped.

[MountiZuma]

Very informative and simply understood, many thanks Michael, pls do give us more lectures on this, thx again!

[amarsankar]

Hi Michael, I'm a java GUI developer but knew only a little in networking. Your video tutorial has just gave me a confidence that I can learn it faster.. Thanks a lot.. Actually I wanted to know about static LSP and landed here for some MPLS understanding.. you have made it clear. Well. thanks once again. Think I can find more video tutorials of yours here to know about .. Keep up the good work!

[mazharahmed01]

WOW,,,LOTS OF EXPLANATION IN SIMPLE WORDS,,THANKS

[jfedah]

thanks .... very well explained

[iluvgoldfrapp]

if u run ipsec over the mpls vpn, is there performance impact or risk of fragmentation?

[borisbonin]

First i would like to say thank you for this great video !!.i'm currently a ccna working as a network support for an IPS vendor in Atlanta.I would like to get more exposure to core routing and voice technologies which is not really possible with the company i work for.Do you have any advise for me? how can i get some mentoring ? do you know of any association of network professional that i can learn from in Atlanta.

[pepomk123]

Awesome. You sir, have earned my subscription.

[junai11]

Thank you!

[markaawi54]

Excellent, well explained !!!

[vvenkat007]

You rock. Explained in it very simply. A layman can understand whats mpls! Keep it up and hope to see in depth explanation of mpls from you. Thanks.

[noiseless2]

very well explaind. does not have any problems to understand you. now mpls make sense ^^

[behnamanisi]

Thanks alot man for making this video you have no idea how much you have helpe me today thank you again . i am doing my 4th year project based on MPLS tunnels

[daikyouju]

Very interesting. Nice job!

[jnstweety]

First thanks for the video - I am new to mpls.

However, I keep hearing that (as you mentioned to jsealey762) a major advantage of mpls is that it allows QOS. If the SP is not running mpls, they might be running plain old ethernet (most likely with 802.1q vlans) - this does allow qos (via diffserv and 802.1p). Most hardware (eth devices) vendors also allow redundancy (eaps, rep, rrpp, epsr). So my question - given that you have hardware which support rings on ethernet, are there any adv of mpls ?

[michaeljcavanaugh]

@jnstweety

“Plain old Ethernet” from a service provider is typically a Metro Ethernet offering. Meaning that Ethernet is used to connect two or more locations in one metropolitan area, while MPLS is typically used to connect both metro locations as well as wide area (WAN) locations. Some Metro Ethernet offering can support QoS across their backbone and some cannot. Check with your provider to see if they have this option.

[michaeljcavanaugh]

@jnstweety

Metro Ethernet is typically a point to point or a point to multipoint connection so redundancy becomes an issue if the host site is lost. Metro Ethernet does not typically provide SIP options, so keep that in mind if you want dialtone delivered over Ethernet at your locations.

[dkhadkladkl]

excellently explained micheal.. thanks a ton

[ni123tin]

nice one man very helpful , please is it possible for you to show us how to configure MPLS network ....simulating on GNS3.

thanks in advance

cheers!!!

[nishansekhon]

Hi Michael, its an excellent video, explanation is wonderful. thanks

[mailziyad]

Hi Michael, Your video is excellent, i could understand more than any other videos. You are a great instructor. keep it up..

[shoelessaj]

Hey Michael, really appreciate your taking the time to explain topics like this on YouTube. Excellent concepts.

[WedHashim]

Michael thanks for this brief and concise explanation excellent tutorial you are great instructor

[jsealey762]

First off, thank you for making this video!

I've been trying to understand the benefits of MPLS and why it is becoming more common for ISP's to switch from the original BGP backbone to the MPLS backbone. Attempting to understand the benefits it would provide to an ISP, the best I can come up with is that it allows QoS to be available over the WAN connection.

My question to you is, what other benefits are there for an ISP to use MPLS over BGP?

Thank you again, great video!

[michaeljcavanaugh]

@jsealey762 - The biggest benefit to a service provider is the ability to classify traffic. Once the SP has this capability they can set up different classes of traffic to provide different service level agreements (SLAs). SLAs can then be sold to a customer based upon their current needs. For example, voice and interactive video traffic both need priority while email traffic typically does not. So the SP can now customer how much of the link (if any) will receive SLAs for each customer.

[homecupe1]

Very useful !!

[JDALSystems]

Great Job explaining this. You should be a teacher!

[dieparra]

grate!!!!!!!!!!!!!!!

[fndsource]

Thank you!

[alisendme82]

Nice video.

[michaeljcavanaugh]

@alisendme82 Thanks. Glad you enjoyed it. :)

[davekrunal46]

How provider edge router determines destination address? I mean, as MPLS doesn't really examining the packet. It just see the labels so how it will come to know where exactly it needs to send (destination address)?

[michaeljcavanaugh]

@davekrunal46 Providers typically use BGP to associate IP addresses with labels. In this way a provider will know which location to switch the packet to reach the destination.

Hope that helps.

Michael

[davekrunal46]

Complex thing explained in simplest manner. Thanks a lot Michael. 

[michaeljcavanaugh]

@davekrunal46 Glad you found it useful. Have a great day.

Michael
