Connecting a logical switch to an NSX Edge services gateway or an NSX Edge logical router provides East-West traffic routing (among the logical switches) or North-South traffic routing to the external world or to provide advanced services.

Procedure

  1. In Logical Switches, select the logical switch to which you want to connect an NSX Edge.
  2. Click Actions > Connect Edge.
  3. Select the NSX Edge to which you want to connect the logical switch.
  4. Select the interface that you want to connect to the logical switch.
    A logical network is typically connected to an internal interface.
  5. Specify the interface details of the NSX Edge.
    1. Enter a name for the NSX Edge interface.
    2. To indicate whether this interface is an internal or an external (uplink) interface, click Internal or Uplink.
    3. Select the connectivity status of the interface.
    4. In Configure Subnets, click Add to add a subnet for the interface.
      An interface can have multiple non-overlapping subnets. Enter one primary IP address and a comma-separated list of multiple secondary IP addresses. NSX Edge considers the primary IP address as the source address for locally generated traffic. You must add an IP address to an interface before using it on any feature configuration.

      If the NSX Edge to which you are connecting the logical switch has Manual HA Configuration selected, specify two management IP addresses in CIDR format.

    5. Enter the subnet prefix length or subnet mask for the interface.
    6. If you are using NSX 6.4.4 or later, click the Advanced tab, and then continue with the remaining steps in this procedure. If you are using NSX 6.4.3 or earlier, directly go to the next step.
    7. Change the default MTU, if necessary.
    8. Under Options, specify the following options.
      Option Description
      Proxy ARP Supports overlapping network forwarding between different interfaces.
      Send ICMP Redirect Conveys routing information to hosts.
      Reverse Path Filter Verifies the reachability of the source address in packets being forwarded. In enabled mode, the packet must be received on the interface that the router might use to forward the return packet. In loose mode, the source address must appear in the routing table.
  6. Enter the fence parameters.

    Configure fence parameters when you want to reuse IP and MAC addresses across different fenced environments. For example, in a cloud management platform (CMP), fencing allows you to run several cloud instances simultaneously with the same IP and MAC addresses isolated or "fenced".

  7. Click Add or Finish.
