VXLAN and BGP EVPN Configuration Guide for Dell EMC SmartFabric OS10 Release 10.5.2

PDF

rd

Configures the Route Distinguisher (RD) value that EVPN routes use.

Syntax
rd {A.B.C.D:[1-65535] | auto}
Parameters
A.B.C.D:[1-65535]
Manually configure the RD with a 4-octet IPv4 address, then a 2-octet-number from 1 to 65535.
auto
Configure the RD to automatically generate.
Default
Not configured
Command mode
EVPN-EVI and EVPN-VRF
Usage information
A RD maintains the uniqueness of an EVPN route between different EVPN instances. Configure a route distinguisher in a tenant VRF used for EVPN symmetric IRB traffic. The RD auto-configures as Type 1 from the overlay network source IP address and the auto-generated EVPN instance ID.

The rd auto command is not supported in EVPN-VRF mode. When you create a VRF in EVPN mode, the RD is automatically generated. The rd A.B.C.D:[1-65535] command is supported in EVPN-VRF mode in 10.5.1 and later releases.

Example 
OS10(config)# evpn
OS10(config-evpn)# evi 10
OS10(config-evpn-evi)# vni 10000
