Router On a Stick : The Router’s interface is divided into sub-interfaces, which acts as a default gateway to their respective VLANs . In this example we’ll use a router for the job. For the distributed architecture, asymmetric IRB (integrated routing and bridging) and symmetric IRB are the two models to achieve inter-subnet routing with EVPN. Since routers have several interfaces with an IP address, all on different network segments, they allow communication between these segments. Nov 18, 2018 · Yes, but whether the inter-VLAN routing supported with Essentials or no? For example, I've two VLANs with SVIs (Gateways for both) residing on the same switch, will they be able to internally communicate with each other without adding a L3 device to allow routing between them. 17 above image).
