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. 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 OS10(config-evpn)# vrf vrf-blue OS10(config-evpn-vrf-vrf-blue)# rd 111.111.111.111:65000 Supported releases 10.4.2.0 or later route-target Configures the Route Target (RT) values that EVPN routes use. Syntax Parameters route-target {auto | value {import | export | both} [asn4]} value {import | export | both} Configure an RT import or export value, or both values in the format 2-octet-ASN:4octet-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 asn4 Configure the RT import and export values to automatically generate. (Optional) Advertises a 4-byte AS number in RT values. Default Not configured Command mode EVPN-EVI and EVPN-VRF 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. Configure a route target in a tenant VRF used for EVPN symmetric IRB traffic.
