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

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.

    set vlans vlan-id 1000 l3-interface 1000
    set vlans vlan-id 2000 l3-interface 2000
  3. Configure the te-1/1/1 interface VLAN ID to 1000.

    set interface gigabit-ethernet te-1/1/1 family ethernet-switching native-vlan-id 1000
  4. Configure the te-1/1/2 interface VLAN ID to 2000.

    set interface gigabit-ethernet te-1/1/2 family ethernet-switching native-vlan-id 2000
  5. Configure the te-1/1/10 interface VLAN ID to 10

    set interface gigabit-ethernet te-1/1/10 family ethernet-switching native-vlan-id 10
  6. Configure ip address for the loopback interface.

    set vlan-interface loopback address 10.10.10.1 prefix-length 32
  7. Configure ip address for the vlan-interface 1000.

    set vlan-interface interface 1000 vif 1000 address 100.10.1.1 prefix-length 24
  8. Configure ip address for the vlan-interface 2000.

    set vlan-interface interface 2000 vif 2000 address 100.20.1.1 prefix-length 24

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

    set vlan-interface interface 2000 vif 2000 address 100.20.2.1 prefix-length 24
  9. Configure static route for the VXLAN ECMP.

    set protocols static route 10.10.10.1/32 next-hop 100.10.2.2
    set protocols static route 10.10.10.1/32 qualified-next-hop 100.20.2.2 metric 1
  10. Configure VTEP interface sources ip address.

    set vxlans source-interface loopback address 20.20.20.1
  11. Configure a VLAN ID 10 to a VNI 1000

    set vxlans vni 1000 interface te-1/1/10 vlan 10
  12. Configure flood vtep ip address for a VNI

    set vxlans vni 1000 flood vtep 10.10.10.1
