When designing for a multi-site fabric that uses an IP-based transit between sites, consideration must be taken if a unified policy is desired between the disparate locations. Lab 8-5: testing mode: identify cabling standards and technologies related. Tight integration with security appliances such as Cisco Adaptive Security Appliances (ASA) and Cisco Firepower Threat Defense (FTD) and analytics platforms such as Stealthwatch and Cognitive Threat Analytics (CTA) enables the network to have the intelligence to quarantine and help remediate compromised devices. Control plane nodes and border nodes should be dedicated devices deployed as redundant pairs. The fabric-mode APs are Cisco Wi-Fi 6 (802.
PIM ASM is used as the transport mechanism. For simplicity, the DHCP Discover and Request packets are referred to as a DHCP REQUEST, and the DHCP Offer and Acknowledgement (ACK) are referred to as the DHCP REPLY. What would most likely solve your problem? The graphic on the right shows square topologies that are created when devices are not connected to both upstream/downstream peers. ● BGP-4—This is the current version of BGP and was defined in RFC 4271 (2006) with additional update RFCs. Lab 8-5: testing mode: identify cabling standards and technologies video. SD-Access supports two options for integrating wireless access into the network. This allows for efficient use of forwarding tables. Two approaches exist to carry SGT information between fabric sites using an IP-based transit, inline tagging and SXP. In SD-Access, the user-defined overlay networks are provisioned as a virtual routing and forwarding (VRF) instances that provide separation of routing tables. During LAN Automation, default-information originate is provisioned under the IS-IS routing process to advertise the default route to all discovered devices. When a host connected to extended node sends traffic to destinations in the same VN connected to or through other fabric edge nodes, segmentation and policy is enforced through VLAN to SGT mappings on the fabric edge node. ● Cisco Plug and Play IOS Agent—This software component is embedded in Cisco devices and communicates to the Cisco Network Plug and Play process using the open plug and play protocol over HTTPS.
NAC—Network Access Control. Ideally, the uplinks should be from the member switches rather than the stack master. The SD-Access fabric control plane node is based on the LISP Map-Server and Map-Resolver functionality combined on the same node. Other fabric sites without the requirement can utilize centralized services for the fabric domain. Each site has its own independent set of control plane nodes, border nodes, and edge nodes along with a WLC. Lab 8-5: testing mode: identify cabling standards and technologies used. Traditional, default forwarding logic can be used to reach these prefixes, and it is not necessary to register the Data Center prefixes with the control plane node. MDF—Main Distribution Frame; essentially the central wiring point of the network. SNMP—Simple Network Management Protocol. ● Group-based policies—Creating access and application policies based on user group information provides a much easier and scalable way to deploy and manage security policies.
SGT value 8000 is leveraged on the ports between the policy extended node and the edge node. The Core layer is the backbone interconnecting all the layers and ultimately providing access to the compute and data storage services located in the data center and access to other services and modules throughout the network. Edge nodes should maintain a maximum 20:1 oversubscription ratio to the distribution or collapsed core layers. In locations where physical stacking is not possible due to the wiring structure, Fabric in a Box can support up to two daisy-chained edge nodes creating a three-tier topology. When connecting PoE devices, ensure that there is enough available PoE power available.
As described later in the Fabric Roles section, the wired and wireless device platforms are utilized to create the elements of a fabric site. Transit control plane nodes are only required when using SD-Access transits. This provides complete control plane and data plane separation between Guest and Enterprise traffic and optimizes Guest traffic to be sent directly to the DMZ without the need for an Anchor WLC. The transit control plane nodes are deployed in their own area, accessible through the SD-Access transit Metro-E network though not in the direct forwarding path between fabric sites. This services block is deployed as a VRF-aware peer if DHCP/DNS and other shared services are site-local. ● VXLAN encapsulation/de-encapsulation—Packets and frames received from outside the fabric and destined for an endpoint inside of the fabric are encapsulated in fabric VXLAN by the border node. When an electrical current travels along the length of a wire, an electromagnetic wave is radiated at right angles to that wire. This assignment is used to implement an equivalence of a peer-to-peer blocking policy. This is analogous to using DNS to resolve IP addresses for host names. Cisco DNA Center has two different support options for extended nodes: classic extended nodes and policy extended nodes. The important concept in fabric site design is to allow for future growth by not approaching any specific scale limit on Day 1 of the deployment.
A border may be connected to in ternal, or known, networks such as data center, shared services, and private WAN. One other consideration for separating control plane functionality onto dedicated devices is to support frequent roaming of endpoints across fabric edge nodes. For optimal forwarding and redundancy, they should have connectivity through both cores, and if interfaces and fiber is available, crosslink to each other though this is not a requirement. The basic concept is that the fusion router is aware of the prefixes available inside each VPN (VRF), generally through dynamic routing, and can therefore fuse these routes together.
Originator-ID allows the MSDP speaker originating a source-active (SA) message to use the IP address of the defined interface as the RP address of the message. When Layer 2 flooding is enabled for a given subnet, all edge nodes will send multicast PIM joins for the respective underlay multicast group, effectively pre-building a multicast shared tree. This is potentially highly undesirable. Most environments can achieve the balance between optimal RP placement along with having a device with appropriate resources and scale by selecting their border node as the location for their multicast Rendezvous Point. The following are the key requirements driving the evolution of existing campus networks. Layer 2 overlays are identified with a VLAN to VNI correlation (L2 VNI), and Layer 3 overlays are identified with a VRF to VNI correlation (L3 VNI). Colocated Control Plane Node and Border Node. The goal of Cisco TrustSec technology is to assign an SGT value to the packet at its ingress point into the network. The edge nodes must be implemented using a Layer 3 routed access design. ● Outside the fabric over devices without Cisco TrustSec capability—SXP allows the control plane communication of SGT to IP mappings over a TCP connection. The SD-Access fabric replaces sixteen (16) of the reserved bits in the VXLAN header to transport up to 64, 000 SGTs using a modified VXLAN-GPO (sometimes called VXLAN-GBP) format described in The Layer 3 VNI maps to a virtual routing and forwarding (VRF) instance for Layer 3 overlays, whereas a Layer 2 VNI maps to a VLAN broadcast domain, both providing the mechanism to isolate data and control plane to each individual virtual network.
The external routing domain is on upstreaming routing infrastructure. Because the default behavior, suppression of broadcast, allows for the use of larger IP address pools, pool size of the overlay subnet needs careful consideration when Layer 2 flooding is enabled. A virtualized control plane node also follows the NFV (Network Function Virtualization) concepts of Software-Defined Networking (SDN) which calls for separating network functions from specialized hardware through virtualization. This allows network systems, both large and small, simple and complex, to be designed and built using modularized components. BGP is used to exchange the reachability information between the two routing domains.
This is a central and critical function for the fabric to operate. An alternative is to deploy a UCS E-series blade servers on the routing infrastructure to virtualize the shared services. As with DNS, a local node probably does not have the information about everything in a network but instead asks for the information only when local hosts need it to communicate (pull model). If this next-hop peer is an MPLS CE, routes are often merged into a single table to reduce the number of VRFs to be carried across the backbone, generally reducing overall operational costs. Hierarchical network models are the foundation for modern network architectures. Together, these make up the Layer 2 and Layer 3 LISP VNIs, respectively, which maintain fabric segmentation even at the control plane communication level. Key Components of the SD-Access Solution.
IS-IS, EIGRP, and OSPF each support these features and can be used as an IGP to build a Layer 3 routed access network. In a fusion device environment, the device performing the leaking may not even be the direct next hop from the border. Finally, the VRF configuration imports and exports routes that are filtered based on these route-maps. In the event of the RADIUS server being unavailable, new devices connecting to the network will be placed in the same VLAN as the development servers. SSO—Stateful Switchover. This upstream infrastructure, while a necessary part of the overall design, is not part of the fabric site and is therefore not automated though SD-Access workflows in Cisco DNA Center. By using Scalable Group Tags (SGTs), users can be permitted access to printing resources, though the printing resources cannot directly communicate with each other. Layer 3 overlays abstract the IP-based connectivity from the physical connectivity as shown in Figure 6. In SD-Access the control plane is based on LISP (Locator/ID Separation Protocol), the data plane is based on VXLAN (Virtual Extensible LAN), the policy plane is based on Cisco TrustSec, and the management plane is enabled and powered by Cisco DNA Center. For example, concurrent authentication methods and interface templates have been added. Once in Inventory, they are in ready state to be provisioned with AAA configurations and added in a fabric role. When PIM-ASM is used in the overlay and multiple RPs are defined within the fabric site, Cisco DNA Center automates the MSDP configuration on the RPs and configures the other fabric nodes within a given fabric site to point to these RPs for a given virtual network.
GRE—Generic Routing Encapsulation. Enabling the optional broadcast flooding (Layer 2 flooding) feature can limit the subnet size based on the additional bandwidth and endpoint processing requirements for the traffic mix within a specific deployment. In traditional networking, network cores are designed to interconnect all modules of the network together, providing IP reachability, and generally have the resources, capabilities, and scale to support being deployed as a Rendezvous Point. For unicast and multicast traffic, the border nodes must be traversed to reach destinations outside of the fabric. HTDB—Host-tracking Database (SD-Access control plane node construct). A shared tree must be rooted at a Rendezvous Point, and for Layer 2 flooding to work, this RP must be in the underlay. The enterprise edge firewall (perimeter firewall) is usually deployed at this location, and Internet traffic from remote sites is tunnel back to this site to be processed by the perimeter security stack before being forwarded to the Internet. A fabric is simply an overlay network. In Figure 15, the graphic on the left shows triangle topologies which are created by devices crosslinking with each other and with their upstream/downstream peers. For OT (Operational Technology), IoT, and BMS (Building Management Systems) migrating to SD-Access, the Layer 2 border handoff can be used in conjunction with Layer 2 Flooding. Users and devices on the corporate overlay network have different access needs. The services block is not necessarily a single entity. Additional design considerations exist when integrating the LAN Automated network to an existing routing domain or when running multiple LAN automation sessions. PD—Powered Devices (PoE).
This brings the advantages of equal cost path routing to the Access layer. This border is the default exit point, or gateway of last resort, for the virtual networks in the fabric site. For campus designs requiring simplified configuration, common end-to-end troubleshooting tools, and the fastest convergence, a design using Layer 3 switches in the access layer (routed access) in combination with Layer 3 switching at the distribution layer and core layers provides the most rapid convergence of data and control plane traffic flows. NBAR—Cisco Network-Based Application Recognition (NBAR2 is the current version).
