– rd auto automatically generates the Route Distinguisher.
4 Congure the Route Target values in EVPN EVI mode.
route-target {auto | value [asn4] {import | export | both}}
Where:
–
route-target auto auto-congures an import and export value for EVPN routes.
– route-target value [asn4]{import | export | both} congures 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 congure 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, congure the VXLAN network ID associated with
the EVPN instance in EVPN EVI mode (1 to 16,777,215). You must congure the same VNI value that you congured for
the VXLAN virtual network (see Congure VXLAN).
