titleNote

Note: Single homed ports connecting a single device with the EVPN VXLAN fabric are not yet supported on VTEP devices. If a server is dual homed to two VTEPs and the connecting link to one of the VTEP fails, the server will still be considered a dual homed device even if there is only one active link connecting it to the fabric.


EVPN MH Basic Configuration

To configure EVPN multihoming on a LAG interface, the user needs to configure an Ethernet Segment identifier (ES-ID) and an Ethernet Segment System MAC. A type-3 ESI value is automatically generated by using these two parameters. The resulting 10-byte ESI value has the following format, where the XXs denote the 6-byte ES System MAC and the YYs denote the 3-byte local ES ID.
