Deployment Guide

An EVPN instance (EVI) spans across the VTEPs that participate in the EVPN. In OS10, configure an EVI in auto-EVI or manual
configuration mode.
• Auto-EVI mode
a. Enable the EVPN control plane in CONFIGURATION mode.
evpn
b. Enable auto-EVI creation for overlay virtual networks in EVPN mode. Auto-EVI creation is supported only if BGP EVPN is used
with 2-byte AS numbers and if at least one BGP instance is enabled with the EVPN address family. No further manual
configuration is allowed in auto-EVI mode.
auto-evi
• Manual EVI configuration mode
a. Enable the EVPN control plane in CONFIGURATION mode.
evpn
b. Manually create an EVPN instance in EVPN mode. The range is from 1 to 65535.
evi id
c. Configure the Route Distinguisher in EVPN EVI mode.
rd {A.B.C.D:[1-65535] | auto}
Where:
• rd A.B.C.D:[1-65535] configures the RD with a 4-octet IPv4 address then a 2-octet-number.
• rd auto automatically generates the RD.
d. Configure the RT values in EVPN EVI mode.
route-target {auto | value [asn4] {import | export | both}}
Where:
• route-target auto auto-configures an import and export value for EVPN routes.
• route-target value [asn4]{import | export | both} configures an import or export value for EVPN
routes in the format
2-octet-ASN:4-octet-number or 4-octet-ASN:2-octet-number.
• The 2-octet ASN number is 1 to 65535.
• The 4-octet ASN number is 1 to 4294967295.
To configure the same value for the RT import and export values, use the both option. asn4 advertises a 2-byte AS
number as a 4-byte route target value. If you specify the
asn4 option, configure the VXLAN network ID associated with
the EVPN instance in EVPN EVI mode, from 1 to 16,777,215. You must configure the same VNI value that you configure for
the VXLAN virtual network. For more information, see Configure VXLAN.

3. Verify the BGP EVPN configuration.
