    Respect to you. I’ve passed my CCNA same year as you in 2007, passed 1 paper in CCNP and 1 paper in CCIP. Until today I’m regret not completed by CCNP and CCIP😅. Being married in 2010 and had 4 kids, I’m simply didn’t have enough time to prepare for the certification.

  • @CCIEOnTheSpectrum
    @CCIEOnTheSpectrum28 күн бұрын

    Didn't understand your question. RD/RT are just like L3VPN, RT is used to install the routes in right MAC-VRF. VNI information helps for data plane forwarding. Split the concept in 2 parts control plan and data plane, would be easier to understand then. MAC to IP?? leaf switches don't need to learn about IP in this case, they are just acting like a layer 2 switch as its VXLAN bridging demo.

    Hello, if there is a server3 connected to a interafce on Cleaf1 with Vlan10, and it has the same IP address as the server 2 which is 172.16.10.2, if the server1 ping 172.16.10.2, will the cleaf1 send the traffic to server 2 through vxlan, or will send to server 3 ?

    Hello, if there is another server3 connected to Vlan 10 interface on Cleaf1 have the same IP address(172.16.10.2) as Server2 , if server1 pings to 172.16.10.2, how does the cleaf1 know where to forward to, will forward to server2 through vxlan , or server3 locally within cleaf1? Thanks

    Forget vxlan for a moment, What would happen if you do that to a layer 2 switch? Consider vxlan fabric a big switch.

  • @CCIEOnTheSpectrum

    Arp broadcast, but scope is only that particular layer 3 link between switches, because the switches know where to send the broadcast packet out, due to that point to point link subnet mask.

    Terrific Explanation. Having completed my CCIE written back in 1998, I think they just started calling it R&S at that point in time, VXLAN was not part of my vernacular, however conceptually it is not uch different than MPLS in concept. Thanks for breaking it down so everyone can get it. If I was to ask for anything additional would be how to troubleshoot and possibly debug end-to-end.

  • @CCIEOnTheSpectrum
    @CCIEOnTheSpectrum6 ай бұрын

    Thanks; a tshoot video is on the list. Hint: Breaking it down into 3 steps is indeed a tshoot strategy. 3 questions to ask for tshoot: is the underlay ok? Is the L2 btwn leaf sw and the host ok? Is the 'vxlan interface' config(vlan-to-vni mapping plus bum traffic) ok?

    Hello, can you explain more VXLAN EVPN L2, L3 and the advantages of using and not using VXLAN EVPN

  • @CCIEOnTheSpectrum
    @CCIEOnTheSpectrum6 ай бұрын

    Yup, its on the list. Bgp evpn is a routing protocol. Like any other routing protocol it advertises network reachability(mac/ip) information. The forwarding of the data remains the same as shown in this video. 2 main benefits of bgp evpn in vxlan: - Auto discovery of remote leaf switches where we have a VNI configured. The flood command used in this demo wouldn't be needed anymore. - MAC address advertisement via bgp evpn. Here in the manual method, MAC address learning is data plane driven. If you understand the manual method demonstrated in this video, then bgp evpn wouldn't be too difficult to understand.

    1) Do all kinds of nerd stuff 2) call your isp, they'll tell you it's in your end and to go back to step 1. 3) repeat steps 1 and 2 like 5 times. 4) get finally connected to the actual technical support which you thought you had already talked with but didn't. 5) "Yes. A network switch at your area broke like 6 hours ago, we've known it the whole time. Your connection should be back up in about an hour. Why are you calling here? Didn't the customer service tell you about this? 🙄"
