V Extensible Local are network

a network virtuiliztion trchnology that addresses the limitations posed by traditional networking.

encapsulates ethernat frames within a udp packet. VLANs had a 12 bit ID so could only have 4096 users .

layer 2 ethernat frames within layer 3 UDP packets. has a vni whish is 24 bit. 16 million IDs

VXLAN tulnnel end pints - performes the encap and decap of ethernet fames into VXLAN packets .normally within hypervisors

VXLAN segments - layer2 network overlaid onter a layer3 network that is then identefied by a unique 24 bit VNI.

Scalability - supports up to 16 million virtual networks.

Flexability - Extend layer 2 networs across diffeent data centers or cloud environments.

improved utilization - Optimizes traffic flows within and across data centers.

Complex to configure.

latency- increased packet size and overhead

configuration - multicast support and unknown unicast traffic is needed. you’ll want to use management and orchestration tools.
