Building DataCenter networks with VXLAN BGP-EVPNCisco Canada
The session specifically covers the requirements and approaches for deploying the Underlay, Overlay as well as the inter-Fabric connectivity of Data Center Networks or Fabrics. Within the VXLAN BGP-EVPN based Overlay, we focus on the insights like forwarding and control plane functions which are critical to the simplicity operation of the architecture in achieving scale, small failure domains and consistent configuration. To complete the overlay view on VXLAN BGP-EVPN, we are going to the insides of BGP and its EVPN address-familiy and extend to about how multiple DC Fabric can be interconnected within, either as stretched Fabrics or with true DCI. The session concludes with a brief overview of manageability functions, network orchestration capabilities and multi-tenancy details. This Advanced session is intended for network, design and operation engineers from Enterprises to Service Providers.
During this presentation, we will cover a deep dive into Aruba Central and its features. Check out the webinar recording where this presentation was used:

This presentation was presented at MUM Indonesia at Bali in 2008. Discussed about how to put extra layer of security into your MikroTik Router using Port Knocking mechanism.
How to manage internet clients of an ISP with PPPoE and MikroTik. For
centralized AAA (Authentication, Authorization and Accounting), freeRadius is used.

In Red Hat Enterprise Linux 7 a new method of interacting with netfilter has been introduced: firewalld.
firewalld is a system daemon that:
Can configure and monitor the system firewall rules
Applications can talk to firewalld to request ports to be opened using the Dbus messaging system
Both covers IPv4, IPv6, and potentially ebtables settings is installed from the firewalld package. This package is part of a base install , but not part of a minimal install
Simplifies firewall management by classifying all network traffic into zones.
The Secret Sauce is the Control Plane, not the Encapsulation
Host Route Distribution decoupled from the Underlay protocol
Use MultiProtocol-BGP (MP-BGP) on the Leaf nodes to distribute internal Host/Subnet Routes and external reachability information
Route-Reflectors deployed for scaling purposes
VXLAN terminates its tunnels on VTEPs (Virtual Tunnel End Point).
Each VTEP has two interfaces, one is to provide bridging function for local hosts, the other has an IP identification in the core network for VXLAN encapsulation/decapsulation.
VXLAN Encapsulation and De-encapsulation occur on T2
Bridging and Gateway are independent of the port type (1/10/40G ports)
Encapsulation happens on the egress port
Decapsulation happens on the ingress port
Service Oriented Architecture
2 or 3 layer network to Leaf & Spine
High density and bandwidth required
Layer 3 ECMP
No oversubscription
Low and uniform delay characteristic
Wire & configure once network
Uniform network configuration
Workload Mobility
Workload Placement
Segmentation
