IP Routing Commands Dell EMC Networking N1500/N2000/N2100-ON/N2200-ON/N3000EON/N3100-ON/N3200-ON Series Switches The Dell Network N1500/N2000/N2100-ON/N2200-ON series supports limited routing and multicast capabilities. See the Users Configuration Guide section "Feature Limitations and Platform Constants" for supported capabilities. Dell EMC Networking routing provides the base Layer 3 support for Local Area Network (LAN) and Wide Area Network (WAN) environments. The Dell EMC Networking switches allows the network operator to build a complete Layer 3+ configuration with advanced functionality. As the Dell EMC Networking defaults to Layer 2 switching functionality, routing must be explicitly enabled on the Dell EMC Networking to perform Layer 3 forwarding. For Dell EMC Networking switches, routing is only supported on VLAN and Loopback interfaces for in-band ports. It is not possible to route packets to or from the out-of-band interface. Static Routes/ECMP Static Routes The operator is able to configure static and default routes with multiple next hops to any given destination. Permitting the additional routes creates several options for the Dell EMC Networking switch operator. 1 The operator configures multiple next hops to a given destination, intending for the router to load share across the next hops. 2 The operator configures multiple next hops to a given destination, intending for the router to use the primary next hops and only use the other next hops if the primary next hops are unusable. The operator distinguishes static routes by specifying a route preference value. A static route with a lower preference value is a more preferred static route. Next hops with the same preference are grouped into a single ECMP route. A less preferred static route is used if the more preferred static route is unusable. (The link is down or the next hop IP address cannot be resolved to a MAC address.) In Dell EMC Networking, the operator deletes an individual next hop from a static route or deletes an entire static route at once. The cost of a static route is always 1 unless configured otherwise by the operator. Layer 3 Routing Commands 1529
