A vxlan routing isn’t available in default configuration on Arista DCS-7050TX, the switch born with vxlan bridging
For activate a feature is needed to dedicate a physical interface to vxlan routing and you can follow those simple steps :
Choose the physical interface and configure it as follow :
interface Ethernet1 traffic-loopback source system device mac no switchport channel-group recirculation 1
now you have to configure a virtual interface :
interface Recirc-Channel1 no switchport switchport recirculation features vxlan
well done, now the vxlan routing is operational!
