DATA CENTER CORE NETWORKING

Traditional Data Center networks utilized a three-tier design that consists of a core, distribution and access layer of switches.

Cisco Application Centric Infrastructure (ACI) is a software-defined networking (SDN) solution designed for data centres.

INTRODUCTION TO SWITCHING PROTOCOLS

Spanning Tree Protocol

Although you have several alternatives to STP that are available for your data center, STP is still a fairly popular technology in the data center environment. SPT build a loop-free logical topology when you have redundant paths in your network.

Rapid PVST+

Rapid Per VLAN Spanning Tree Plus (Rapid PVST+) is an updated, faster implementation of STP that allows you to create one spanning tree topology for each VLAN.

INTRODUCTION TO SWITCHING PROTOCOLS

Port Channels

INTRODUCTION TO SWITCHING PROTOCOLS

Virtual Port Channels

A pair of Cisco Nexus switches that use vPC present themselves to other network devices as a single logical Layer 2 switch. However, the two switches remain as two separately managed switches with independent management and control planes. 1998-2022

INTRODUCTION TO ROUTING PROTOCOLS

OSPFv2 and OSPv3

OSPF is an IGP, used to distribute routing information within a single autonomous system (AS). Designed expressly for IP networks, OSPF supports IP subnetting and tagging of externally derived routing information. OSPF also allows packet authentication and uses IP multicast when sending and receiving packets. OSPFv3 expands on OSPF Version 2, providing support for IPv6 routing prefixes. 1998-2022 NetCom Learning Interested in training?

INTRODUCTION TO ROUTING PROTOCOLS

Border Gateway Protocol

BGP is a routing protocol that provides loop-free routing between different domains, such as organizations or autonomous systems. Cisco Nexus Switches support BGP version 4, which also includes multiprotocol extensions, referred as Multiprotocol-Border Gateway Protocol (MP-BGP). It allows BGP to carry routing information for IP multicast routes and multiple Layer 3 protocol address families.

ABOUT FIRST HOP REDUNDANCY PROTOCOL

FHRP

First Hop Redundancy Protocol (FHRP) is a general term for a networking protocol that is designed to protect the default gateway by allowing two or more routers or Layer 3 switches to provide a backup for the gateway IP address. If one first-hop router fails, the backup router will within a few seconds by default take over the address.

ABOUT FIRST HOP REDUNDANCY PROTOCOL

HSRP

HSRP uses a group of routers to provide redundancy. You would configure each router an individual routerspecific IP address. All routers in the HSRP group are also configured with a shared group IP address known as the virtual IP address. Routers generate a shared virtual group MAC address from the HSRP group number. This group IP address presents the image of a single, fault-tolerant router to the client network.

ABOUT FIRST HOP REDUNDANCY PROTOCOL

VRRP

Virtual Router Redundancy Protocol (VRRP) is similar to HSRP, both in operation and configuration. The VRRP primary is analogous to the HSRP active gateway, while the VRRP backup is analogous to the HSRP standby gateway. A VRRP group has one primary device and one or multiple backup devices. A device with the highest priority is the elected primary.

ABOUT MULTICAST PROTOCOLS AND OVERLAY

• IP multicast is a bandwidth-conserving technology that reduces traffic by delivering a single stream of information simultaneously to potentially thousands of businesses and homes.

• IP multicast routing enables a host (source) to send packets to a group of hosts (receivers) anywhere within the IP network by using a special form of IP address called the IP multicast group address.
