Next we setup the layer 3 VLAN interfaces and configure IP addresses for these interfaces. The MTU value of layer 3 interfaces is set to 1450 to ensure there is enough space for the overlay VXLAN header. The switch will complain and refuse to commit the configuration if MTU size is not set to 1450.
Then we setup VXLAN VNIs, enable VLAN to VNI mapping and map VNIs to VLAN IDs. Finally we enable IP routing on the device and configure BGP related parameters such as router ID, BGP neighbor and enabling advertising all VNIs.
