Important: The area ID for the interconnect link must not be the same as the area ID for the uplink.

To configure the Fabric Link Configuration for a Layer 3 distributed core fabric:

1. Navigate to the Network >

Fabric Name

> Configure and Deploy screen.

2. From the Deploy Fabric pull-down menu, select the Pre-Deployment Configuration option.

The Introduction screen displays.

3. Review the Introduction screen and gather the useful information to prepare your fabric for deployment.

4. Click the Next button.

The Fabric Link Configuration screen displays.

5. In the Start IP Address Range/Prefix area, enter the starting IP address and prefix.

The prefix must be from 8 to 29.

6. In the Loopback IP Address Range/Prefix area, enter the loopback address range and prefix.

The prefix must be from 8 to 26.

7. In the Area ID field, use the default setting of 0 or enter the area ID.

The area ID is a value from 0 and 65535. The uplinks or interlinks must be in area 0 for OSPF.

Pre-deployment – Step 1b: Uplink Configuration

The Uplink Configuration screen for a Layer 3 and Layer 3 with Resiliency (Routed VLT) fabric displays the port

bandwidth and the number of specified ports (read-only fields) entered on the Bandwidth and Port Count screen. To

configure the uplink protocol for the edge port uplinks to the WAN, use the Uplink Configuration screen. For information

about for a uplinks for a Layer 3 distributed core fabric, see Distributed Core Terminology.

NOTE: When the Open Shortest Path First (OSPF) is selected for both uplinks and interlinks, one of uplinks or

interlinks must be in area 0.

To configure the uplink protocol for the edge port uplinks to the WAN for a Layer 3 distributed core fabric:

1. Navigate to the Network >

Fabric Name

> Configure and Deploy screen.

2. From the Deploy Fabric pull-down menu, select the Pre-deployment Configuration option.

3. Navigate to the Uplink Configuration screen.

4. In the Protocol Settings, select a routing protocol (OSPF, IBGP, or eBGP) for the edge port uplinks. The number of

uplinks is specified in the Bandwidth and Port Count screen.

AFM automatically populates the range of IP addresses that belong to the /30 subnet.

a) For OSPF, for each specified uplink, enter the local IP address, remote neighbor IP address, and area ID. A valid

area ID area is from 0 to 65535.

b) For iBGP, for each specified uplink, enter the local IP address, remote neighbor IP address, local AS number.

For the AS number, enter a value from 1 to 4294967295.

c) For eBGP, for each specified uplink, enter the local IP, remote neighbor IP address, local AS number, and

remote AS number. For the AS number, enter a value from 1 to

4294967295.

5. Click Next to go the Downlink Configuration screen.

Pre-deployment – Step 1d : Downlink Configuration (Layer 3)

Downlinks are edge port links which connect to servers, switches, or ToRs. When you enable the ToR configuration, the

leaves function as a ToR. When you disable the ToR configuration, the leaves function as a switch. The port bandwidth

for the downlinks is 1 Gb, 10 Gb, or 40 Gb (a read-only field). For more information about downlinks, see Distributed Core

Terminology and VLT Terminology.
