Deployment Guide

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 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. The route-target
command is supported in EVPN-VRF mode in 10.5.1 and later releases. In EVPN-VRF command mode, the
manual route-target configuration should be unique across VRFs.
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
OS10(config)# evpn
OS10(config-evpn)# vrf vrf-blue
OS10(config-evpn-vrf-vrf-blue)# route-target auto
Supported
releases
10.4.2.0 or later
router-mac
Configure the local router MAC address that is used by remote VTEPs as the destination address in VXLAN encapsulated
packets sent to the switch.
Syntax
router-mac mac-address
Parameters
mac-address
Enter the MAC address in nn:nn:nn:nn:nn:nn format.
Default Not configured
Command mode EVPN
Usage
information
The EVPN router MAC address is encoded in the router's MAC extended community in MAC/IP Type 2
and IP-prefix Type 5 route updates. It also serves as the destination MAC address in VXLAN encapsulated
packets sent to the switch. In a VLT domain, configure the same router MAC address on both VLT VTEP
peers.
Example
OS10(config-evpn)# router-mac 00:01:02:03:04:05
Supported
releases
10.5.1 or later
70 BGP EVPN for VXLAN
