VxLAN on HPE Aruba Networks Networks Campus Access Switches

[@evamartinserrano5202]

those access switches con interoperate with VMware NSX solutions? VTEP and/or VXLAN interop?

Hi, as far as i understood, VXLan is working as an GRE tunell, isn´t it?

As I read, you can terminate vxlan not just to loopback interfaces but to any L3 interface. Since access switches already have in your demo an IP on VLAN 1 (which is I assume the in band management IP), can the VXLAN be deployed between the in band management IP of VLAN 1?This way, if we have L2 switches that have in band management IP on one of the VLAN that is already routed in the network, and have a trunk port to a central firewall doing the routing (static), then we don't have to add extra routing for L0 interfaces, but just add tunnels between the VLAN 1 IP addresses. Is this a possible idea? I keep seeing that the recommended is the L0 interface, but can this type of setup work too? Thanks!

Hi Daniel, yes you can potentially do that. The IP interfaces have to be reachable by the VTEP's. reason for using loopback interfaces is that typically loopback interfaces are always up. In case a physical L3 interface (or a VLAN) ends up in a down state, you will also lose the VxLAN connectivity. In conclusion, yes you can use physical IP's, but best practice is to use loopback interfaces.

With VXLAN, is it possible for VLAN 1 to communicate with other VLANs such as 100 and 110 and vice-versa?

[@hermanrobers]

Yes, but it is not done in VXLAN, it is done on the VTEP which has L3 capabilities after the VXLAN has been removed. You typically do this on your core or aggregation to reduce the complexity.

What application are you using for the topology demo? in 1:46. Thanks

[@AirheadsBroadcasting]

Not sure if I understand the question. The client can use 802.1X, or MAC Auth, or Captive Portal. It's independent of the client and authentication source, which can be any source that is supported by ClearPass (local, or remote like an AD).

@@AirheadsBroadcasting Sorry I meant the application you are using for the presentation. I need to show topology diagrams with animation and thought yours looked good :) Thanks

@@nickhughes5777 I think those are powerpoint animations. If you ever see a presentation from Dik it ALWAYS has bouncing balls flying around the screen. It's like his trademark. In powerpoint you select an object and go animation > path animation.

@@nickhughes5777 As Joe said, it's just PowerPoint. Moving and bouncing balls is my signature.. :-).

great thanks for the reply's guys! :)

great video! what about mtu?

[@AirheadsBroadcasting]

Hi Denis, yes MTU is important. Make sure that you have jumbo frames (or at least mini jumbos) enabled in the datapath.

Hi could you write your name correct ?
