The EVPN introduced the concept of Integrated Routing and Bridging based on EVPN to address inter-subnet communication between VMs which are belong to different VxLAN segments. It is also called inter-VxLAN routing with 2 options; Symmetric IRB and Asymmetric IRB. In the asymmetric IRB we only have the concept of L2VNI. We also have another …
The distributed IP anycast gateway applies the anycast network concept“one to the nearest association.” Anycast is a network addressing and routing implementation in which the data traffic from an endpoint is routed topologically to the closest node in a group of gateways. The function of the Anycast Layer 3 gateway is natively embedded with the …
VXLAN allows us to create a logical topologies in the Data Center for our virtual machines. With VxLAN we are able to create a layer 2 network on top of layer 3 infrastructure. In the Data Centers VMs needs to be deployed in a specific segment of the network. These VMs can be moved from …
VXLAN allows us to create layer 2 networks over layer 3 infrastructure. The VXLAN base use case is to connect two or more layer three network domains and make them look like a common layer two domain. In the Data center environment this allows virtual machines on different networks to communicate as if they were …
A gateway is a device that ensures communication between VXLANs identified by different VNIs and between VXLANs and non-VXLANs. With the centralized gateway routing Layer 3 gateways are configured on one device, usually on Spine layer. It is the easiest way of deploying gateways but it has some disadvantages; There will be a lot of …
VxLAN is becoming de facto standard for the Data Center networking envitoments. In current and future implementations, VxLAN provides an overlay over a Data Center Spine-Leaf networks. It is decoupled from the Underlay which is static and robust. In the early implementations of Data Center Networks, there was no such a thing that applications are …
