- In this video, Charles shares another topic he's been studying while going down the CCIE Enterprise Infrastructure blueprint: VRF-aware routing. Here he takes a look at configuring an MPLS Layer 3 VPN to route separate VRF traffic over that connection.

I started watching KV 7-8 years ago at a time when I knew nothing about networks and I mean practically zero. I now have an Msc in Data Networks and Security and I continue to come back and watch his videos. I have always referred to his material when Im have trouble comprehending a concept and he has been my backbone along my journey. I always learn something, what a legend of modern day computer networking!
Excellent job , keep doing labs as clear and concise as this one .
Excellent video, very well presented, clear and concise and no filler. Straight to the point of content 👍
Excellent demonstration, I’m fairly sure it’s the best I’ve come across so far!
I'm currently doing an internship at a networking company and my tasks deal with this kinda stuff, so this video really was helpful to me. Good job, I really appreciate it.
This is the best MPLS lab video I've seen so far. Thanks.
Marvelously explained. Loved every bit of it. Great work.
You are brilliant ....thanks from India
thanks for the clear and straight forward example and explanation. More power to your channel!
This should be a template for all the tutorials. Excellent piece of work.
Very informative, thanks charles & Kevin
Excellent Piece , straight to the point
Thank You for this important video fro those who want to learn about mpls and vpn.
Awesomely clear explanation and easy to follow. Just enrolled in your ENARSI Udemy course.
Outstanding Video and presentation.. Very informative, quick and to the point! :)
Thanks immensely. Well explained as usual
Clear and easy to understand,
Thank you…
Clearly explained, great piece
Very good session, thanks Charles.
Beautiful! Thanks Charles, Kevin. ✌🏻
thank you.. very helpful, presentation and pacing and making it easy to understand.. thank you so much!!!!
Clearly explained. Thank you!
Thank you Charles
Aazing tutorial THANKS for such effort!!
Great work....very informative
Nicely explained, thank you!
Great video man!
thank you so much for this vids
Great Content!!!
Excellent
Hello, great video and thank you! How would you implement internet breakout for each CE uplink?
Excellent ...Thank you
Excellent!!!!!
Excellent video. Is the complete configuration for the lab available? Especially the MPLS core section?
I'd just like to interject for a moment.
What you guys are referring to as VRF with MPLS,
is in fact, VRF/MP-BGP, or as I've recently taken
to calling it, VRF plus MP-BGP. VRFs are not a
routing construct unto itself, but rather another
component of a fully functioning prefix advertisement
system made useful by MP-BGP's NLRI, underlying use of
TCP, and vital scalability capabilities comprising a
full dynamic routing protocol as defined by the IETF.
Excellent video, what if we want to add another PE and another CE for Customer A? i've configured a lab and everything works fine (mpls, ospf between new PE and CE and ospf between new PE and ISP Core) but i cant redistribute routes in BGP-VPN between PE1 and newPE, and PE2 and newPE
Nice.
On point.
Great video, I need to watch it twice though. lol
Tq Kevin - frm Malaysia
Sir thank you sir!
thanks charles
Good job thank you
Great job of explaining this subject.. Q: rather than configure each OSPF/BGP neighbor using OSPF1-3 and BGP using various VRFs, can the there be a GLOBAL OSPF/BGP neighbor relationship between the VRFs and use RD and Import/Exports?
Perfection
Because i am unable to pay my fees thats why my tutuor is not teach to me mpls L3.....but your video is helpful for me to understand the mpls L3
Thanks so much
Hi, I tried to do the laboratory similar to your topology, I can see on the routing table of the customer Edge router the subnets on the other side of customer subnets, but when I tried to ping, it cant's reach, and tried to traceroute it stops on the PE router.
I am using GNS3 for my laboratory, I am thinking that maybe its not working the same as the actual cisco devices
Thank you for this video. It was very helpful.
Would it also be possible to use OSPFv3 with address-families on the PE Routers to avoid the multiple OSPF processes?
That would be smart decision , and less , less work and less complicated
also more advanced and secure than OSPFv2
Thank you thank you thabk you :D
WOW! It is very enterprise loaded!
But is that not also possible If you have BGP-Routing in the Core?
Excellent!! I got a doubt, maybe it's a silly one, but why did you use a public IP address between PEs and CEs?
Another question is...
In this scenario, I thought it'll be used things like IPSEC and GRE Tunnels to do the VPN, how the VPN was implemented in this case?
In many VPN services like L3VPN or VXLAN EVPN the VPN does not mean encryption it's basically mean that you separate customer 1 routes from customer 2 routes.
why when we redistribute bgp to OSPF in PE1, we don't need the command "address-family ipv4 vrf Customer-A", but when we redistribute OSPF to BGP, we need to use it
I love you sir
Did i miss something? Maybe Im just confused.. How come you are seeing mpls labels at the end when all that was done was bgp, vrf to segmentate and some ospf? Didnt see any commands that ive read about on cisco's documentation like, mpls bgp forwarding on interface, enabling of LDP etc. New to mpls so maybe there are many different ways to do it.
he did not show it, my assumption is that it was already configured.
Mpls was already configured 1:48
i think you should set rd ASN:1
and route target 1:1for first vrf and 1:2 for second and then show how to import 1:1 on 2nd vrf so they could be interconnected.
What's the command to have the two of them connected?
😀😀😀

Thanks
That’s a lot of CDs.
redistributing from ospf to bgp is understandable -Customer routes will be advertised in backbone.
why there is a need to redistribute again bgp to ospf.Customer dont want to know about the service providers routes.
don't use ospf against customers unless you want problems. EIGRP instead or BGP or even RIP.
First viewer thanks for this video
