Layer 3 routing protocol becomes more and more important to industrial application edge network topologies, such as intelligent transportation management and applications related to urban infrastructure. Industrial applications normally work with amount of industrial devices within an isolated network, with few monitoring interfaces at the field site.

In order to establish inter-VLAN communication (i.e routing between hosts belonging to different VLANs) you need to have a Layer 3 routing engine in the network. This L3 engine is provided by the Nexus Core Switch (which must have an appropriate Layer 3 image and license). Inter-Vlan Routing with a Layer 3 Switch - Tech Like This Routing Out the Layer 3 Switch. Set the Gateway of last resort on the layer 3 switch specifying the next hop router/ASA. ip route nextHopIP. If you are doing NAT for both VLANs so they can access the internet, make sure to set the correct ACLs for both subnets. Layer 2 vs Layer 3 Switch: How to Choose for VLAN?

Instead, frames arriving in a routed port trigger the Layer 3 routing logic, including. Stripping off the incoming frame’s Ethernet data-link header/trailer. Making a Layer 3 forwarding decision by comparing the destination IP address to the IP routing table. Adding a new Ethernet data-link header/trailer to …

The pattern matching and caching on Layer 3 switches is similar to the pattern matching and caching on a router. Both use a routing protocol and routing table to determine the best path. However, a Layer 3 switch has the ability to reprogram the hardware dynamically with the current Layer 3 routing information. This is what allows for faster VLAN Routing with Layer 3 Switch SVIs > IP Routing in the
