SRv6 End.DX2 Function

In the MPLS Data plane, we have a lot of experience over P2P L2VPN services. SRv6 can provide same functionality with MPLS Data plane and MPLS VPN label. Instead of MPLS Tunnel label and VPN label we can use Segment Routing Header (SRH). SRH is a new type of IPv6 Routing Extension Header. Any kind of function …


Why VxLAN

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 …


Segment Routing and LDP Interoperability

Segment Routing TI-LFA Double Segment Example

Segment Routing TI-LFA Repair Path Insertion

Before Segment Routing was introduced, IP FRR and Loop-Free Alternates (LFAs) were not widely deployed. In these implementations the level of coverage depended on the network topology. When SR combined with FRR techniques, Fast Reroute can deliver 100% network coverage regardless of the topology. That is called TI-LFA (Topology Independent – Loop Free Alternate) Here …

VxLAN Bridging

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 …


VxLAN Fundamentals

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 …
