    Study Notes

    VMware NSX-T Data Center Exam Study Notes

    • Core Concepts: The VMware Certified Professional (VCP) 2V0-11.24 NSX-T Data Center exam assesses knowledge of VMware NSX-T, a network virtualization platform. Topics often include Border Gateway Protocol (BGP).

    BGP Fundamentals in NSX-T

    • Establishment: BGP peering and adjacency establishment is a fundamental aspect of network communication.
    • Advertisement and Propagation: BGP uses attributes like AS-PATH, MED, and Local Preference to advertise and propagate routes across networks. Weight is also considered, but is vendor-specific.
    • Path Selection: The path selection process in BGP considers attributes like AS-PATH, MED, and Local Preference to choose the optimal route. Weight is also considered, but is vendor-specific.

    NSX-T Implementation

    • Configuration: Configuring BGP in NSX-T Tier-0 Gateways is a key exam topic.
    • Deployment Modes: Candidates should understand Active-Active and Active-Standby deployment modes in NSX-T.
    • Route Redistribution: Redistribution between Tier-0 and Tier-1 gateways is crucial for proper network routing.
    • Timers: BGP timers (Keepalive and Hold Time) are important for maintaining the BGP session.

    Route Management

    • Prefix Lists: Filtering routes using prefix lists is a technique used in BGP configuration.
    • BGP Policies: Route maps and BGP policies are used in route management to control which routes are accepted and distributed.
    • Equal Cost Multipath (ECMP): ECMP is a feature supporting BGP which enables optimal routing with multiple paths between equal-cost routes. A key benefit is improved north-south traffic throughput and redundancy.

    Troubleshooting

    • Peer Status: Diagnosing BGP peer status is critical for troubleshooting routing problems.
    • Debugging: Using NSX CLI commands facilitates debugging and troubleshooting in NSX-T environments. Specific commands include get bgp neighbor, get logical-routers, get route table.
    • Route Inspection: Inspecting received and advertised routes helps determine the path of traffic, allowing for easy identification of network issues. -Specific CLI commands to inspect routes include get bgp advertised-routes, get bgp neighbor received-routes, and get route table.
    • CLI Commands (Specific): Knowledge of specific CLI commands (e.g., get bgp neighbor, get logical-routers, get route table, show ip bgp summary, show ip bgp) is essential for troubleshooting.

    NSX-T Tier-0 Gateway Configuration

    • Primary Function: Providing north-south connectivity between the NSX environment and the physical network is the core function of a Tier-0 Gateway.
    • Deployment Mode: Active-Active mode is recommended for high availability and redundancy in Tier-0 Gateways.
    • Connectivity to Physical Network: The Tier-0 Gateway connects to the physical network through Edge Nodes configured with uplinks to external routers.
    • ECMP Benefits: Using ECMP with Tier-0 Gateways can improve north-south traffic throughput and redundancy by using equal-cost multiple paths.

    Tier-0 & Tier-1 Gateway Relationships

    • Interaction: Tier-0 and Tier-1 Gateways interact to manage traffic flow in the NSX-T network; Tier-0 is primarily responsible for north-south traffic and Tier-1 for east-west traffic.
    • Uplink Management: Uplink interfaces connect the Tier-0 Gateways to the physical network and require proper configuration.
    • Routing Protocols: Route maps and redistribution help manage traffic between gateways using protocols like BGP or OSPF.

    Additional Important Topics

    • Dynamic Routing (BGP, OSPF): Mastering dynamic routing configuration, including BGP and OSPF, in NSX-T environments is vital.
    • NAT Types (DNAT, SNAT): Understanding and configuring various NAT types in NSX-T to allow private networks to reach the public internet is necessary.
    • Logical Switches: An understanding of logical switches and segments in NSX-T is required.
    • Distributed Firewall (DFW) and Edge Firewall: Overview of these firewall features and related security policies are important.
    • High Availability (HA): Configuring HA for Tier-0 and Tier-1 Gateways is critical for high availability and redundancy.
    • Monitoring and Troubleshooting: Utilizing vRealize Network Insight (vRNI), CLI commands, and other monitoring tools is vital for proactive troubleshooting.
    • Network Function Virtualization (NFV): Understanding NSX-T's role in virtualized network functions is a key area.
    • VPN Configurations: Learn about various VPN configurations in NSX-T (IPSec VPN, Site-to-Site VPN) for security and remote access.
    • Virtualization and Networking fundamentals: A solid foundation of networking and virtualization principles is essential.
    • ECMP Configuration: Understanding ECMP configuration on NSX-T Tier-0 Gateways.
    • vRNI Usage: Using vRNI for monitoring and troubleshooting NSX network issues.
    • Traceflow: Use Traceflow to simulate and trace traffic across your NSX network.
