Route-Reflectors (RRs)

The number of spine switches that are used as route reflectors for transporting BGP traffic. Choose 2 or 4 from the drop-down box. The default value is 2.

To deploy spine devices as RRs, Nexus Dashboard Fabric Controller sorts the spine devices based on their serial numbers, and designates two or four spine devices as RRs. If you add more spine devices, existing RR configuration won’t change.

Increasing the count – You can increase the route reflectors from two to four at any point in time. Configurations are automatically generated on the other two spine devices designated as RRs.

Decreasing the count – When you reduce four route reflectors to two, remove the unneeded route reflector devices from the fabric. Follow these steps to reduce the count from 4 to 2.

1. Change the value in the drop-down box to 2.

2. Identify the spine switches designated as route reflectors.

   An instance of the rr_state policy is applied on the spine switch if it’s a route reflector. To find out if the policy is applied on the switch, right-click the switch, and choose View/edit policies. In the View/Edit Policies screen, search rr_state in the Template field. It is displayed on the screen.

3. Delete the unneeded spine devices from the fabric (right-click the spine switch icon and choose Discovery > Remove from fabric).

   If you delete existing RR devices, the next available spine switch is selected as the replacement RR.

4. Click Deploy Config in the fabric topology window.

You can preselect RRs and RPs before performing the first Save & Deploy operation. For more information, see Preselecting Switches as Route-Reflectors and Rendezvous-Points.

iBGP Peer-Template Config

Add iBGP peer template configurations on the leaf switches to establish an iBGP session between the leaf switch and route reflector.

If you use BGP templates, add the authentication configuration within the template and uncheck the Enable BGP Authentication check box to avoid duplicate configuration.

In the sample configuration, the 3DES password is displayed after password 3.

router bgp 65000
    password 3 sd8478fswerdfw3434fsw4f4w34sdsd8478fswerdfw3434fsw4f4w

The following fields can be used to specify different configurations:

• iBGP Peer-Template Config – Specifies the config used for RR and spines with border role.

• Leaf/Border/Border Gateway iBGP Peer-Template Config – Specifies the config used for leaf, border, or border gateway. If this field is empty, the peer template defined in iBGP Peer-Template Config is used on all BGP enabled devices (RRs, leafs, border, or border gateway roles).

In a brownfield migration, if the spine and leaf use different peer template names, both iBGP Peer-Template Config and Leaf/Border/Border Gateway iBGP Peer-Template Config fields need to be set according to the switch config. If spine and leaf use the same peer template name and content (except for the “route-reflector-client” CLI), only iBGP Peer-Template Config field in fabric setting needs to be set. If the fabric settings on iBGP peer templates do not match the existing switch configuration, an error message is generated and the migration will not proceed.

VRF Template

Specifies the VRF template for creating VRFs.

Network Template

Specifies the network template for creating networks.

VRF Extension Template

Specifies the VRF extension template for enabling VRF extension to other fabrics.

Brownfield Overlay Network Name Format

Enter the format to be used to build the overlay network name during a brownfield import or migration. The network name should not contain any white spaces or special characters except underscore (_) and hyphen (-). The network name must not be changed once the brownfield migration has been initiated. See the Creating Networks for the Standalone Fabric section for the naming convention of the network name. The syntax is [<string> | $$VLAN_ID$$] $$VNI$$ [<string>| $$VLAN_ID$$] and the default value is Auto_Net_VNI$$VNI$$_VLAN$$VLAN_ID$$. When you create networks, the name is generated according to the syntax you specify.

The following list describes the variables in the syntax:

• $$VNI$$: Specifies the network VNI ID found in the switch configuration. This is a mandatory keyword required to create unique network names.

• $$VLAN_ID$$: Specifies the VLAN ID associated with the network.

  VLAN ID is specific to switches, hence Nexus Dashboard Fabric Controller picks the VLAN ID from one of the switches, where the network is found, randomly and use it in the name.

  We recommend not to use this unless the VLAN ID is consistent across the fabric for the VNI.

• <string>: This variable is optional and you can enter any number of alphanumeric characters that meet the network name guidelines.

An example overlay network name: Site_VNI12345_VLAN1234

For example, if you require some additional configurations to be pushed to the device and be available post device bootstrap, they can be captured in this field, to save the desired intent. After the devices boot up, they will contain the configuration defined in the Bootstrap Freeform Config field.

Copy-paste the running-config to a freeform config field with correct indentation, as seen in the running configuration on the NX-OS switches. The freeform config must match the running config. For more information, see Enabling Freeform Configurations on Fabric Switches.

Hourly Fabric Backup

Select the check box to enable an hourly backup of fabric configurations and the intent.

The hourly backups are triggered during the first 10 minutes of the hour.

Scheduled Fabric Backup

Check the check box to enable a daily backup. This backup tracks changes in running configurations on the fabric devices that are not tracked by configuration compliance.

Scheduled Time

Specify the scheduled backup time in a 24-hour format. This field is enabled if you check the Scheduled Fabric Backup check box.

Select both the check boxes to enable both back up processes.

The backup process is initiated after you click Save.

The scheduled backups are triggered exactly at the time you specify with a delay of up to two minutes. The scheduled backups are triggered regardless of the configuration deployment status.

The number of fabric backups that will be retained on NDFC is decided by the Settings > Server Settings > LAN Fabric > Maximum Backups per Fabric.

The number of archived files that can be retained is set in the # Number of archived files per device to be retained: field in the Server Properties window.

You can also initiate the fabric backup in the fabric topology window. Click Backup Now in the Actions pane.

Enable Netflow

Check this check box to enable Netflow on VTEPs for this Fabric. By default, Netflow is disabled. On Enable, NetFlow configuration will be applied to all VTEPS that support netflow.

If netflow is not enabled at the fabric level, an error message is generated when you enable netflow at the interface, network, or vrf level. For information about Netflow support for Cisco NDFC, refer to Netflow Support.
