Overview

sd Configuring Infra: NDFC Site-Specific Settings

This section describes how to configure site-specific Infra settings for on-premises sites.

Procedure

1.

Log in to your Cisco Nexus Dashboard and open the Cisco Nexus Dashboard Orchestrator service.
2.

In the left navigation menu, choose Configure > Site to Site Connectivity.
3.

In the main pane, click Configure.
4.

In the left pane, under Sites, choose a specific NDFC.
5.

In the right <Site> Settings sidebar, specify the Multi-Site VIP.

This address is used for the intersite L2 BUM and L3 multicast traffic. The IP address is deployed in all border gateway switches that are part of the same fabric.

Note

If the site you are configuring is part of the NDFC Multi-Site Domain (MSD), this field will be prepopulated with the information imported from NDFC. In this case, changing the value and redeploying the configuration, impacts traffic between the sites that are part of the MSD.

You can choose to Auto Allocate this field, which allocates the next available address from the Multi-Site Routing Loopback IP Range you defined in the previous section.
6.

Within the <fabric-name> tile, choose the border gateway.
7.

In the right <border-gateway> setting sidebar, specify the BGP-EVPN ROUTER-ID and BGW PIP.

For border gateways that are part of a vPC domain, you must also specify a VPC VIP.

You can also choose to deploy a shared border configuration, this configuration allows you to share these services through these devices, while also providing a means to cross the "border" from the internal sites to the Internet. For more information on see, Configuring Shared Border in Cisco Nexus Dashboard Fabric Controller.
8.

Click Add Port to configure the port that connects to the IPN.

Note

This release does not support importing the port configuration from the NDFC. If you are configuring a site which is already part of the NDFC Multi-Site Domain (MSD), you must use the same values that are configured in NDFC.

You can use the Inherit BGP Authentication and BFD radio button to inherit settings across, sites and fabrics.

NDFC Settings - Add Port

Provide the following information specific to your deployment for the port that connects this border gateway to a core switch or another border gateway:

  • From the Ethernet Port ID drop-down, choose the port that connects to the IPN.

  • In the IP Address field, enter the IP address and netmask.

  • In the Remote Address field, provide the IP address of the remote device to which the port is connected.

  • In the Remote ASN field, provide the remote site's Autonomous System Number.

  • In the MTU field, enter the port's maximum transmission unit.

    Maximum transmission unit of the spine port must match MTU on the IPN side.

    You can specify either inherit or value between 576 and 9000.

  • For BGP Authentication, you can pick either None or Simple (MD5) or Cisco.

    Provide the Authentication Key if you choose Simple or Cisco authentication methods.

  • Check the BFD Enabled, Log Neighbor, and BGP Send Community radio buttons to inherit all these features to all the multisite underlay interfaces.

  • Route Tag is used to configure the data path across all the switches and is propagated to all the nodes in the fabric. Loopback 0, 1 and 100. Select Enable Redistribute Direct if the route tag is specified.
