18 GENERAL IP ROUTING
This chapter provides information on network functions including:
◆ Ping – Sends ping message to another node on the network.
◆ Trace – Sends ICMP echo request packets to another node on the
network.
◆ Address Resolution Protocol – Describes how to configure ARP aging
time, proxy ARP, or static addresses. Also shows how to display
dynamic entries in the ARP cache.
◆ Static Routes – Configures static routes to other network segments.
◆ Routing Table – Displays routing entries learned through dynamic
routing and statically configured entries.
◆ Equal-cost Multipath Routing – Configures the maximum number of
equal-cost paths that can transmit traffic to the same destination
OVERVIEW
This switch supports IP routing and routing path management via static
routing definitions (page 753) and dynamic routing protocols such as RIP,
OSPFv2, OSPv3
13
, or BGPv4
13
. 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. However, when the
switch is first booted, default routing can only forward traffic between local
IP interfaces. As with all traditional routers, static and dynamic routing
functions 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 228), assign all
ports that belong to the same group to these VLANs (page 231), and then
assign an IP interface to each VLAN (page 691 or page 695). 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.
