Requirements

This example uses the following hardware and software components:

  • An Trident-II Series switch

  • PICOS OS Release more than 2.5 version

Overview

In this example, VXLAN ECMP is configured to run on a VXLAN domain. VTEP interfaces sources are configured to the loopback address. Interfaces are configured for VLAN tagging and encapsulation. Static route protocols is configured to facilitate unicast routing.

Topology

The VXLAN that comprise the networks include:

  • SW1 VNI 1000: VTEP 10.10.10.1: VLAN 10

  • SW2 VNI 1000: VTEP 20.20.20.1: VLAN 10

  • SW1 IP Adress: 100.10.1.1 and IP Address: 100.20.1.1

  • SW2 IP Adress: 100.10.2.1 and IP Address: 100.20.2.1

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and copy and paste the commands into the CLI.

Configuring VXLAN Step-by-Step Procedure

The following example shows how to set up a basic VXLAN ECMP configuration with VXLAN domain. To configure VXLAN ECMP on Trident-II Series switches, follow these steps:

Configure VXLAN Step-by-Step for SW1

  1. Configure the VLAN ID to 10 for vxlan domain. 

    set vlans vlan-id 10

     

  2. Configure the VLAN ID to 1000 and 2000 for ip routing.

     

  3. Configure the te-1/1/1 interface VLAN ID to 1000.

     

  4. Configure the te-1/1/2 interface VLAN ID to 2000.

     

  5. Configure the te-1/1/10 interface VLAN ID to 10

     

  6. Configure ip address for the loopback interface.

     

  7. Configure ip address and MTU for the vlan-interface 1000.

     

  8. Configure ip address and MTU for the vlan-interface 2000.

     

  9. Configure static route for the VXLAN ECMP.

     

  10. Configure VTEP interface sources ip address.

     

  11. Configure a VLAN ID 10 to a VNI 1000

     

  12. Configure flood vtep ip address for a VNI

     

Configure VXLAN Step-by-Step for SW2

  1. Configure the VLAN ID to 10 for vxlan domain. 

     

  2. Configure the VLAN ID to 1000 and 2000 for ip routing.

     

  3. Configure the te-1/1/1 interface VLAN ID to 1000.

     

  4. Configure the te-1/1/2 interface VLAN ID to 2000.

     

  5. Configure the te-1/1/10 interface VLAN ID to 10

     

  6. Configure ip address for the loopback interface.

     

  7. Configure ip address and MTU for the vlan-interface 1000.

     

  8. Configure ip address and MTU for the vlan-interface 2000.

     

  9. Configure static route for the VXLAN ECMP.

     

  10. Configure VTEP interface sources ip address.

     

  11. Configure a VLAN ID 10 to a VNI 1000

     

  12. Configure flood vtep ip address for a VNI
