 vEdge is the Cisco SD WAN component that provides a secure data plane with remote vEdge routers. vEdge routers are the devices that sit at the edge of the SD WAN fabric and connect to the WAN transports, such as MPLS, Internet, or LTE. vEdge routers establish secure IPsec tunnels with other vEdge routers in the fabric and exchange routing and policy information with the vSmart controller. vEdge routers also perform application-aware routing, QoS, and security functions on the data plane traffic. vEdge routers can be physical or virtual devices and can be deployed in branch, campus, data center, or cloud environments1.

The other options, vBond, vSmart, and vManage, are not the components that provide a secure data plane with remote vEdge routers. vBond is the orchestrator that performs the initial authentication and authorization of vEdge routers and assigns them to a vSmart controller. vSmart is the controller that distributes the control and data policies and the network topology information to the vEdge routers. vManage is the management platform that provides centralized configuration, monitoring, and troubleshooting of the SD WAN fabric1. References := : 1: Cisco SD-WAN Getting Started Guide - Cisco SD-WAN Overview [Cisco SD-WAN] - Cisco

 SD-Access Fabric is a network architecture that uses three key technologies to create a virtual overlay network on top of the physical underlay network. These technologies are:

VXLAN: Virtual Extensible LAN is a tunneling protocol that encapsulates Layer 2 frames in UDP packets and transports them over an IP network. VXLAN enables the creation of large-scale virtual networks that span multiple Layer 3 domains. VXLAN is used in SD-Access Fabric to carry user traffic between different fabric nodes and to provide network segmentation based on virtual network identifiers (VNIs).

TrustSec: Cisco TrustSec is a security framework that uses software-defined segmentation to enforce granular access policies based on the identity and context of users, devices, and applications. TrustSec uses scalable group tags (SGTs) to classify endpoints into logical groups and applies security policies based on the source and destination SGTs. TrustSec is integrated with SD-Access Fabric to provide micro-segmentation within a virtual network and to simplify policy management across the fabric.

LISP: Locator/ID Separation Protocol is a routing protocol that decouples the endpoint identity (EID) from its location (RLOC) in the network. LISP uses two types of devices: ingress tunnel routers (ITRs) and egress tunnel routers (ETRs) to map EIDs to RLOCs and to encapsulate and decapsulate packets. LISP is used in SD-Access Fabric to provide control plane functions, such as endpoint registration, discovery, and mobility. LISP also enables seamless integration of SD-Access Fabric with external networks, such as the Internet, WAN, or data center.

The other options, OTV, RSVP, and MPLS, are not used in SD-Access Fabric. OTV is another tunneling protocol that extends Layer 2 connectivity across Layer 3 domains, but it is not compatible with VXLAN. RSVP is a signaling protocol that reserves network resources for quality of service (QoS), but it is not required for SD-Access Fabric. MPLS is a packet-switching technology that labels packets and forwards them based on label switching routers (LSRs), but it is not involved in SD-Access Fabric. References := : Cisco SD-Access Solution Design Guide (CVD) - Cisco1, Cisco Software-Defined Access - Cisco Software-Defined Access Solution Overview2

Some of the statements that are true regarding Cisco SD-WAN license tiers are:

With Pro license, control and data policies are supported2. This license tier enables network operators to define and enforce policies for traffic shaping, quality of service (QoS), application optimization, and security2.

With Plus license, split-tunnel is supported3. This license tier enables network operators to use split-tunneling technology to route traffic through different paths based on application or user preferences3.

With Enterprise license, vAnalytics is included4. This license tier enables network operators to use vAnalytics feature to collect and analyze data from various sources such as endpoints, applications, devices, networks, and cloud services4.

Cisco ISE integrates with more than 60 third-party solutions that span across security and network portfolios. These solutions include network access devices, firewalls, threat detection and prevention systems, vulnerability scanners, endpoint management platforms, cloud services, and more. By integrating with these solutions, Cisco ISE can leverage the information and capabilities of these solutions to enhance the identity and access management, network visibility and segmentation, threat detection and response, and policy enforcement of the network. Some of the examples of third-party solutions that integrate with Cisco ISE are:

Fortinet: Fortinet integrates with Cisco ISE through pxGrid to share user and device information, security group tags, and endpoint posture status. This enables Fortinet to apply granular and dynamic firewall policies based on the identity and context of the endpoints1.

Tripwire: Tripwire integrates with Cisco ISE through pxGrid to share vulnerability and compliance data of the endpoints. This enables Cisco ISE to apply appropriate network access policies based on the risk and compliance level of the endpoints2.

Splunk: Splunk integrates with Cisco ISE through REST APIs to collect and analyze the logs and events generated by Cisco ISE. This enables Splunk to provide network and security insights, dashboards, reports, and alerts based on the Cisco ISE data3.

 ISE automation BYOD flow is a process that allows users to self-enroll their devices to the network without requiring IT intervention. The process consists of three main functions: certificate enrollment, device registration, and supplicant provisioning.

Certificate enrollment is the function that allows users to obtain a digital certificate from a certificate authority (CA) for their devices. This certificate is used to authenticate the device to the network and provide secure communication. ISE supports different CA options, such as Microsoft CA, Cisco ISE CA, or third-party CA .

Device registration is the function that allows users to register their devices to the network and associate them with their identity. This enables ISE to apply policies based on the device type, ownership, and posture. ISE supports different device registration methods, such as portal-based, API-based, or bulk import .

Supplicant provisioning is the function that allows users to install and configure a network access client (supplicant) on their devices. This client is used to connect to the network using the appropriate protocols and settings. ISE supports different supplicant provisioning methods, such as native supplicant, Cisco Network Setup Assistant (NSA), or Cisco AnyConnect Secure Mobility Client (AnyConnect) .

 The default interval for BFD packets is 1 second. BFD uses Hello packets to detect the liveness and faults on a connection. BFD Hello Interval packet is sent at the default interval of 1000 milliseconds on all connections1. This command can be used to change the hello interval for a transport color. The interval for transmitting and receiving BFD packets can also be configured on the interface level or the BFD session level, depending on the device and the protocol234. The BFD detection time is calculated as the product of the local detection multiplier and the agreed remote transmission interval. The lower the BFD detection time, the faster the BFD session can detect a fault. However, a lower BFD detection time also consumes more system resources and bandwidth. Therefore, the BFD detection time should be configured according to the network situation and performance requirements. References:

Self-healing functionality on vEdges refers to the ability of the vEdge routers to recover from failures or errors that affect their connectivity or performance. Two examples of self-healing functionality on vEdges are:

In software upgrade process, rolling back to the previously running software image when connectivity to vManage fails: When a vEdge router is upgraded to a new software version, it maintains a backup copy of the previous software image and configuration. If the vEdge router loses connectivity to the vManage controller during or after the upgrade process, it automatically reboots and restores the previous software image and configuration. This ensures that the vEdge router can resume its normal operation and reconnect to the vManage controller1.

With configuration change, rolling back the configuration change when loss of connectivity to vManage: When a vEdge router receives a configuration change from the vManage controller, it applies the change and verifies the connectivity to the vManage controller. If the vEdge router detects that the configuration change has caused a loss of connectivity to the vManage controller, it automatically reverts the configuration change and restores the previous configuration. This prevents the vEdge router from being isolated from the vManage controller and the rest of the SD-WAN fabric2.

According to the Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers document1, the three Cisco recommendations on “How to Win” are:

Explain support for 3rd party network devices: Cisco ISE can integrate with more than 60 third-party solutions that span across security and network portfolios. This enablesCisco ISE to leverage the information and capabilities of these solutions to enhance the identity and access management, network visibility and segmentation, threat detection and response, and policy enforcement of the network. By explaining this support, the customer can see the value and flexibility of Cisco ISE in their existing or heterogeneous network environment2.

Explain architectural advantage of holistic Cisco solution: Cisco ISE is part of the Cisco Digital Network Architecture (DNA), which is a comprehensive and open platform that provides end-to-end network automation, assurance, security, and analytics. By explaining the architectural advantage of the holistic Cisco solution, the customer can see how Cisco ISE works seamlessly with other Cisco DNA components, such as Cisco DNA Center, Cisco SD-Access, Cisco SD-WAN, Cisco TrustSec, and Cisco Stealthwatch, to deliver a unified and consistent network experience across wired, wireless, and cloud domains3.

Talk about Cisco’s focus on Security and integration with StealthWatch, Sourcefire, WSA, vulnerability scanner to make smarter policy decisions: Cisco ISE is a core component of the Cisco security portfolio, which provides comprehensive and integrated security solutions for the network. By talking about Cisco’s focus on security and integration with other security products, such as StealthWatch, Sourcefire, WSA, and vulnerability scanner, the customer can see how Cisco ISE can provide enhanced visibility, threat detection, and policy enforcement for the network. For example, Cisco ISE can use the data from StealthWatch to identify anomalous or malicious behavior of the endpoints and apply appropriate network access policies based on the threat level4.

The other options, show case Cisco portfolio or ISE feature set during PoC and demonstrate complex policy flows, rather show case Wizards and enhanced context visibility, are not Cisco recommendations on “How to Win”. Showing case Cisco portfolio or ISE feature set during PoC is a general best practice, but not a specific recommendation for winning the customer. Demonstrating complex policy flows, rather than showing case Wizards and enhanced context visibility, is a counterproductive approach, as it can confuse or overwhelm the customer with technical details, rather than highlighting the benefits and simplicity of Cisco ISE. References := : 2: Cisco Identity Services Engine Administrator Guide, Release 2.7 - ISE Security Ecosystem Integration Guides [Cisco Identity Services Engine] - Cisco2, 1: Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers1, 3: Cisco Identity Services Engine - Cisco3, 4: Cisco Identity Services Engine Administrator Guide, Release 2.7 - Stealthwatch Integration [Cisco Identity Services Engine] - Cisco4
