## AI overview

A hands-on lab introduces Integrated Routing and Bridging with EVPN MAC-VRF instances by adding anycast gateway IP addresses to VLAN interfaces. The lab can run on netlab-enabled infrastructure, GitHub Codespaces, or an Apple-silicon Mac using an Arista cEOS container.

## Source excerpt

Most EVPN documentation rushes into the complexities of symmetric IRB, type-5 EVPN routes, and EVPN IP-VRFs, but if you want to master a technology, it's better to take it slow and proceed with small steps. In today's lab exercise, we'll do just that: explore what happens when you add IP addresses (we'll use anycast gateways) to VLAN interfaces tied to EVPN MAC-VRF instances. Explore the lab exercise You can run the lab on your own netlab-enabled infrastructure (more details), but also within a free GitHub Codespace or even on your Apple-silicon Mac (installation, using Arista cEOS container, using VXLAN/EVPN labs).
