17 General IP Routing
This chapter provides information on network functions including:
Static Routes – Configures static routes to other network segments.
Routing Table – Displays routing entries learned through dynamic routing and
statically configured entries.
Overview
This switch supports IP routing and routing path management via static routing
definitions. When IP routing is functioning, this switch acts as a wire-speed router,
passing traffic between VLANs with different IP interfaces, and routing traffic to
external IP networks via the default gateway or static routes. However, when the
switch is first booted, default routing can only forward traffic between local IP
interfaces. As with all traditional routers, static routing must first be configured to
work.
Initial Configuration By default, all ports belong to the same VLAN and the switch provides only Layer 2
functionality. To segment the attached network, first create VLANs for each unique
user group or application traffic (page 171), assign all ports that belong to the same
group to these VLANs (page 173), and then assign an IP interface to each VLAN
(page 663 or page 667). By separating the network into different VLANs, it can be
partitioned into subnetworks that are disconnected at Layer 2. Network traffic
within the same subnet is still switched using Layer 2 switching. And the VLANs can
now be interconnected (as required) with Layer 3 switching.
Each VLAN represents a virtual interface to Layer 3. You just need to provide the
network address for each virtual interface, and the traffic between different
subnetworks will be routed by Layer 3 switching.
