Command mode EVPN-EVI
Usage information A RD maintains the uniqueness of an EVPN route between different EVPN instances. The RD auto-configures as
Type 1 from the overlay network source IP address and the auto-generated EVPN instance ID.
Example
OS10(config)# evpn
OS10(config-evpn)# evi 10
OS10(config-evpn-evi)# vni 10000
OS10(config-evpn-evi)# rd 111.111.111.111:65535
Supported
releases
10.4.2.0 or later
route-target
Configures the Route Target (RT) values EVPN routes use.
Syntax
route-target {auto | value {import | export | both} [asn4]}
Parameters
value {import
| export |
both}
Configure an RT import or export value, or both values, in the format 2-octet-ASN:4-
octet-number or 4-octet-ASN:2-octet-number.
• The 2-octet ASN or number is 1 to 65535.
• The 4-octet ASN or number is 1 to 4294967295.
auto
Configure the RT import and export values to automatically generate.
asn4
(Optional) Advertises a 4-byte AS number in RT values.
Default Not configured
Command mode EVPN-EVI
Usage information
A RT determines how EVPN routes distribute among EVPN instances. Configure each RT with an import and
export value. When the EVPN routes advertise, the RT export value configured for export attaches to each route.
The receiving VTEP compares a route export value with the local RT import value. If the values match, the routes
download and install on the VTEP.
• For 2-byte autonomous systems, the RT auto-configures as Type 0 from the 2-byte AS and the 3-byte VNI—
Type encoded as 0x0002.
• For 4-byte autonomous systems, the RT auto-configures as Type 2 from the 4-byte AS and the 2-byte EVI—
Type encoded as 0x0202.
Example
OS10(config)# evpn
OS10(config-evpn)# evi 10
OS10(config-evpn-evi)# vni 10000
OS10(config-evpn-evi)# rd 111.111.111.111:65535
OS10(config-evpn-evi)# route-target 1:3 both
