Anyone using an MX as their layer 3 device for a large Layer 3 routing on the MX is process switched. Routing is jut another process on the MX appliance. Packets are forwarded based on the kernel scheduler. Layer 3 routing on a traditional Catalyst switch will be hardware switched. When a packet arrives on the ingress queue, hardware asics do what they do. Layer 3 Routing - The Meraki Community If the Alcatel only has that one layer 3 interface then you don't need to route anything via it (you need at least two layer 3 interfaces to really do routing). In that case you would simply add a layer 3 interface for that subnet onto one of your other devices, such as your core switches. 0 Kudos Reply.

In this article we will be implementing Layer 2 NAT with Layer 3 Routing on a pair of Stratix 5700 NAT switches with Routing enabled. When we create multiple VLANs on one Stratix 5700 switch we can connect multiple identical machines and leverage Layer 3 routing to route between the various VLANs.

In order to increase routing speeds, many "cut-through" techniques were used, which perform an "inspect the first packet at layer 3 and send the rest at layer 2" type of processing. How to Configure L2 and L3 InterVlan Routing on Cisco 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

Set the Gateway of last resort on the layer 3 switch specifying the next hop router/ASA. ip route 0.0.0.0 0.0.0.0 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?
