Feature Information |
|---|---|---|
| Cisco IOS XE Bengaluru 17.16.1 |
Single-Active Mode |
In single-active mode, only one Virtual Tunnel Endpoint (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. Multihoming in single-active mode was introduced only in the form of dual-homing, allowing a CE device to be connected to two VTEPs. |
| Cisco IOS XE 17.18.2 |
All-Active Mode |
In all-active mode, downstream devices can connect to multiple VTEPs simultaneously using a standard PortChannel interface. |
| Cisco IOS XE 17.18.2 |
Hierarchical BGP Sessions |
With hierarchical BGP sessions, EVPN multihoming with fabric control planes enables scalable and resilient campus networks by replacing legacy STP architectures with VXLAN fabric cores. |
| Cisco IOS XE 17.18.2 |
Routed Overlay |
Routed overlay is virtual network built on top of a physical infrastructure and it uses VXLAN to securely connect endpoints. |
| Cisco IOS XE 17.18.2 | Overlay: Distributed Anycast Gateway Routed |
Distributed Anycast Gateway (DAG) is an overlay architecture that allows multiple leaf switches or VTEPs to share the exact same default gateway IP and MAC address for a given subnet across the fabric. |
| Cisco IOS XE 17.18.2 |
Overlay: Distributed Anycast Gateway Routed |
In DAG bridged overlay inter-subnet traffic between different bridge domains is routed centrally, while this traffic remains bridged natively across the fabric. |
