ARP with EVPN Asymmetric IRB

In a previous blog post , I described the ARP issues you&rsquo;ll encounter when using centralized routing (on a spine switch) between two EVPN MAC-VRF instances (a fancy name for a VLAN encapsulated in VXLAN or MPLS). That blog post established a baseline that will help us unravel the ARP behavior in a more realistic scenario: asymmetric Integrated Routing and Bridging (IRB). That&rsquo;s a…
