External Border Gateway Protocol (eBGP) is configured on the SmartFabric leaf switch interfaces to peer with the Tier-0 gateway on the m01 NSX edge cluster. ‎Figure 2 shows the eBGP autonomous system numbers (ASNs) and IP addresses used in this example and their locations. The example peer interface addresses and ASNs specified here are configured on the m01 NSX Tier-0 gateway during edge cluster deployment.

Table 4.      eBGP peer configuration policy examples

Note: Bidirectional Forwarding Detection (BFD) is enabled as a best practice. After deploying the NSX edge cluster, also enable BFD on the Tier-0 gateway in NSX Manager. For details, refer to VMware Cloud Foundation 4.5 on Dell VxRail.

To configure eBGP, do the following in the SFS UI or OMNI:

1. Select Network > Routing Configuration.

2. Expand eBGP Peer Configuration.
3. Click CREATE.
4. Enter the values from the first five columns of the first row in the table above.
5. Click CREATE to apply the settings.
6. Repeat steps 3 through 5 for each row in the table above. When complete, the eBGP peer configuration table appears as shown in the figure below. The Tier-0 gateway policies are outlined in red.

Figure 10.
eBGP Tier-0 gateway policies configured

Associate the eBGP policies with the SmartFabric leaf switches as follows:

1. Select the radio button next to the first policy, 1a-tier0-1 in this example.

2. In the right pane, click +ADD ROUTE TO SWITCH.
3. Select the applicable switch from ‎Table 3.
4. Click ADD.

When complete, the right pane appears as shown:
