| - | * ESI—An Ethernet segment must have a unique nonzero identifier, called the Ethernet segment identifier (ESI). The ESI is encoded as a 10-octet integer. When manually configuring an ESI value, the most significant octet, known as the type byte, must be 00. When a single-homed CE device is attached to an Ethernet segment, the entire ESI value is zero. The Ethernet segment of the multihomed Device CE1 has an ESI value of 00: | ||
| - | * EVI—An EVPN instance (EVI) is an EVPN routing and forwarding instance spanning all the PE routers participating in that VPN. An EVI is configured on the PE routers on a per-customer basis.
