rd
Congures the Route Distinguisher (RD) value used in EVPN routes.
Syntax
rd {A.B.C.D:[1-65535] | auto}
Parameters
A.B.C.D:
[1-65535]
Manually congure the route distinguisher with a 4-octet IPv4 address followed by a 2-
octet-number. (1-65535).
auto
Congure the route distinguisher to be automatically generated.
Default Not congured
Command mode EVPN-EVI
Usage information A route distinguisher (RD) maintains the uniqueness of an EVPN route between dierent EVPN instances. The RD
auto-congures 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
Congures the route target (RT) values used in EVPN routes.
Syntax
route-target {auto | value {import | export | both} [asn4]}
Parameters
value {import
| export |
both}
Congure 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
Congure the RT import and export values to be automatically generated.
asn4
(Optional) Advertises a 4-byte AS number in route target values.
Default Not congured
Command mode EVPN-EVI
Usage information
A route target determines how EVPN routes are distributed among EVPN instances. Congure each RT with an
import and export value. When the EVPN routes are advertised, the RT export value congured for export is
attached to each route. The receiving VTEP compares a route's export value with the local RT's import value. If the
values match, the routes are downloaded and installed on the VTEP.
• For 2-byte autonomous systems, the RT auto-congures 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-congures as Type 2 from the 4-byte AS and the 2-byte EVI
(Type encoded as 0x0202).
