EVPN VXLAN Overlay Network for IPv4 Bridged Traffic |
EVPN VXLAN overlay network for IPv4 bridged traffic is a Layer 2 overlay network that allows host devices within the same subnet to send IPv4 bridged traffic to each other using a Layer 2 virtual network instance (VNI). |
EVPN VXLAN Overlay Network for IPv4 Routed Traffic |
EVPN VXLAN overlay network for IPv4 routed traffic is a Layer 3 overlay network that allows host devices in different Layer 2 networks to send IPv4 routed traffic to each other using a Layer 3 VNI and an IP VRF. | |
Layer 2 Broadcast, Unknown Unicast, and Multicast (BUM) Traffic Forwarding using Underlay Multicast |
Multi-destination Layer 2 broadcast, unknown unicast, and multicast (BUM) traffic in an EVPN VXLAN network is replicated through a multicast group in the underlay network and forwarded to all the endpoints of the network. |
|
Leaf Functionality |
A leaf switch sits on the edge of a BGP EVPN VXLAN fabric and is connected to the host or access devices. It functions as a virtual tunnel end point (VTEP) and performs encapsulation and decapsulation. |
|
EVPN VXLAN Integrated Routing and Bridging |
EVPN VXLAN integrated and bridging (IRB) allows the VTEPs in a VXLAN network to forward both Layer 2 or bridged traffic and Layer 3 or routed traffic. It is implemented as symmetric and asymmetric IRB. |
|
EVPN VXLAN Distributed Anycast Gateway |
EVPN VXLAN distributed anycast gateway is a default gateway addressing mechanism that enables the use of the same gateway IP address across all the leaf switches that are part of a VXLAN network. Support was introduced with manual MAC address configuration on the Layer 2 VNI VLAN’s switch virtual interface (SVI) on all VTEPs as the only method to enable the feature. |
|
DHCP Relay for IPv4 Traffic in BGP EVPN VXLAN Fabric |

MAC Aliasing for EVPN VXLAN Distributed Anycast Gateway |
MAC aliasing allows the leaf switches in an EVPN VXLAN network to advertise the MAC addresses of their Layer 2 VLAN’s SVI as the gateway MAC address to all the other leaf switches in the network. MAC aliasing removes the need to explicitly configure the same MAC address on the Layer 2 VNI VLAN’s SVI on all VTEPs in order to enable distributed anycast gateway. |

Cisco IOS XE Bengaluru 17.6.1 |
Private VLANs (PVLANs) in a BGP EVPN VXLAN Fabric |
BGP EVPN VXLAN allows you to extend a PVLAN across the VTEPs in an EVPN fabric overlay. The extension uses isolated and community VLANs to provide features like subnet management and sub segmentation of a broadcast domain in the fabric. |
Cisco IOS XE Bengaluru 17.6.1 |
EVPN VXLAN Multi-homing in Single-active Redundancy Mode |
Multi-homing provides redundancy in the connection between a customer edge (CE) device and a VTEP by connecting the customer network with multiple VTEPs in an EVPN VXLAN network. In single-active redundancy mode, only one VTEP, among a group of VTEPs that are attached to the particular ethernet segment, is allowed to forward traffic to and from that ethernet segment. Multi-homing in single-active redundancy mode was introduced only in the form of dual-homing, allowing a CE device to be connected to two VTEPs. |
Cisco IOS XE Bengaluru 17.6.1 |

The route leaking feature provides the import and export of routes between an EVPN-enabled VRF and the Global Routing Table (GRT). By enabling the import and export of the EVPN learned routes into the GRT, the border node provides access to services such as DNS or DHCP to the hosts in the fabric. |
Cisco IOS XE Bengaluru 17.6.2 |
Data MDT Support for L3 TRM |
Data MDTs are purpose built underlay MDTs to provide optimized forwarding in the MVPN and EVPN core. |

Cisco IOS XE Cupertino 17.9.1 |
BGP EVPN VXLAN over IPsec |
An IPsec-based underlay network securely transports the VXLAN-encapsulated packets between the source and destination VTEPs. Securing the BGP EVPN VXLAN data traffic using IPsec tunnel encrypts the data and maintains data integrity. Support for this feature was introduced only on the Cisco Catalyst 9300X Series Switches. |
Cisco IOS XE Dublin 17.10.1 |
BGP EVPN VXLAN with IPv6 in the Underlay (VXLANv6) |
Introduced support for IPv6 addressing in the underlay of a BGP EVPN VXLAN fabric. In a new deployment, you can build your BGP EVPN VXLAN fabric with IPv6 underlay. For an existing BGP EVPN VXLAN fabric with IPv4 underlay, you can seamlessly migrate to an IPv6 or dual stack underlay. |
Cisco IOS XE Dublin 17.11.1 |
EVPN Microsegmentation |
BGP EVPN VXLAN integrates Cisco TrustSec to provide microsegmentation and end-to-end access control with the propagation of the security group tag (SGT). Using security group-based access control lists (SGACLs), you can control the operations that a user can perform, based on the security group assignments and destination resources in a VXLAN campus fabric. |
EVPN VXLAN Multi-Homing |
BGP EVPN is enhanced to restrict the ethernet segment operations to the EVPN-controlled VLANs on the trunk port. This allows traditional Layer 2 domains to co-exist with the Layer 2 VNI-enabled VLANs at access layer. It also allows selective VLAN migration to overlay VXLAN segmentation. |
|
Dynamic BGP Peering for EVPN |
Support for BGP dynamic neighbor sessions is extended to the L2VPN EVPN address family. |
|
EVPN Route Map Support |
The Leaf, Spine and Border nodes of a BGP EVPN fabric now support route map for the L2VPN address family. With route map support, the BGP attributes and their values can be modified to customize the routing policy based on the requirement. The routing policy can be applied for both inbound and outbound EVPN routes. |
|

TRM over BGP EVPN VXLANv6 |
TRM over BGP EVPN VXLANv6 follows the industry standard IETF RFCs 6513 and 6514 to support rich multicast applications over the BGP EVPN VXLAN fabric network. The Cisco Catalyst 9000 series switches provide flexibility to transport IPv4 multicast applications in overlay networks while the underlay network can be built on single-stack IPv6 only. |
Cisco IOS XE Dublin 17.12.1 |
BGP EVPN VRF Auto RD and Auto RT |
BGP EVPN Layer 3 overlay VRF configuration is simplified with the introduction of new CLIs to auto generate the route distinguisher (RD) and route target (RT) for a VRF. |

|
Cisco IOS XE 17.13.1 |
TRM over BGP EVPN VXLANv6 |
TRM over BGP EVPN VXLANv6 follows the industry standard IETF RFCs 6513 and 6514 to support rich multicast applications over the BGP EVPN VXLAN fabric network. The Cisco Catalyst 9000 series switches provide flexibility to transport IPv4 and IPv6 multicast applications in overlay networks while the underlay network can be built on single-stack IPv6 only. |
Simplified CLIs for the BGP EVPN VXLAN Layer 2 and Layer 3 Overlay Configuration |
Layer 2 Overlay Configuration: You can now configure a range of VLANs using a single CLI - vlan configuration vlan-id-range . By defining the member evpn-instance command under the VLAN configuration, EVPN Instance (EVI) ID and VXLAN Layer 2 VNI ID (L2VNI) are autogenerated for each VLAN. You also have the option of auto creating the EVI and L2VNI from a predefined service profile to simplify the provisioning of Layer 2 overlay. Layer 3 Overlay Configuration: BGP EVPN Layer 3 overlay VRF configuration is further simplified in this release with the introduction of new keywords in the vnid command in the VRF submode. If you have enabled auto generation of route target for a VRF, Cisco IOS XE 17.13.1 provides you with the option of auto generating the Layer 3 VNI (L3VNI) or specifying a value for L3VNI. It also provides the option to automatically associate the NVE interface with the given VRF and acquire the core SVI and core VLAN, using the vnid vnid [ evpn-instance [vni{vni-id | auto} [core-vlan vlan-num]] ] command. |
