Dc Network Diagram With Core Switch And Internal Firewall

THe Dr site shall have p-2-p link with DC and have ROuter2900--gtASA--gtL2 switch--gtservers. Our routing is done in router and all vlans are in core switch and natting done in UTM. THe diagram is attached. i need help in figuring out how to configure this.Need to setup such that if the web services and internal app fail in DC then DR picks up.

This data center network architecture diagram, created using EdrawMax, illustrates the core components of a modern IT infrastructure. It includes a firewall, backbone switches, storage systems, virtual machines VMs, and hosts, all connected within a 15U server rack. This diagram provides a clear overview of how data flows between components, ensuring efficient network security and resource

Firewall, Distribution layer, Core Layer. 1. Access Layer. As the name suggests, access layers are there to grant access to the end devices and users. In a LAN network, this access is given to the end users, as against the WAN network, wherein the remote users are given access to a corporate network having WAN connections.

Internet lt--gt Fortigate lt--4x1G--gt Core lt--2x10G--gt Access Switches. The current network design consists of a firewall Fortigate 100D, a pair of stacked quotnetwork corequot L3 switches Netgear M4300 configured for redundancy and then an access layer of switches Spine and Leaf off the core for end-user devices. Switches are connected over 10G

Familiarize yourself with this diagram before reading the subsequent sections, which provide details on each layer of this recommended architecture. Figure 2-1 Data Center Multi-Tier Model Topology . Data Center Core Layer . The data center core layer provides a fabric for high-speed packet switching between multiple aggregation modules.

Note The VSG uses Two-Tier to refer to a topology consisting of Layer 2 multi-chassis LAGs between a collapsed routedLayer 2 core layer and a Layer 2 only set access switches compared to a spine-and-leaf network using routed links between spine and leaf layers. Host information in a two-tier data center is populated using traditional bridge learning and ARP methods.

Core Router The central router within the data center for core network routing. The network diagram shows the detailed configuration and connectivity among the components The service connection from Prisma Access terminates on the NGFW in the data center. The NGFW is connected to both Prisma SD-WAN IONs using Edge BGP peer configuration.

The advantage of a core switch is backplane switching the ability to pass traffic across the core without 1Gbps or even 10Gbps limits, achieving maximum performance. Generally, the backbone of the network is where switching ends and routing begins, with core switches serving as both switching and routing engines.

Very often, once a firewall is placed in the datacenter network, each firewall interfacezone is associated with one VLAN, and the hosts sit in that VLAN. The firewall serves as the default gateway. The diagram below illustrates a sample of this typical quotlayer 2quot network redundancy of firewalls, core switches are omitted for simplicity.

your question is a real world design and it depends, there would need to be some routing on both the firewall and core switch. these days ngfw and L3 core switches are really powerful and should be enough to handle extra services eg routing.
