Routing Interfaces

Dell EMC Networking N1500, N2000, N2100-ON, N3000E-ON,

N3100-ON Series Switches

This chapter describes the routing (layer-3) interfaces the Dell EMC

Networking N-Series switches support, which includes VLAN routing

interfaces, loopback interfaces, and tunnel interfaces.

The topics covered in this chapter are:

• Routing Interface Overview

• Default Routing Interface Values

• Configuring Routing Interfaces (Web)

• Configuring Routing Interfaces (CLI)

For information about configuring IPv6 characteristics on routing interfaces,

see "IPv6 Routing" on page 1403.

For configuration examples that configure VLAN routing interfaces, see "IP

Routing Configuration Example" on page 1135 in the IP Routing chapter. For

a configuration example that includes tunnel and loopback interface creation,

see "Interconnecting an IPv4 Backbone and Local IPv6 Network" on

page 1258.

Routing Interface Overview

Routing interfaces are logical interfaces that can be configured with an IP

address. Routing interfaces provide a means of transmitting IP packets

between subnets on the network.

What Are VLAN Routing Interfaces?

VLANs divide a single physical network (broadcast domain) into separate

logical networks. To forward traffic across VLAN boundaries, a layer-3 device,

such as router, is required. Dell EMC Networking N-Series switches can act as

layer-3 devices when you configure VLAN routing interfaces. VLAN routing
