Configuring IP Unicast Routing
This section describes the commands associated with configuring
IP unicast routing on the switch. Configuring routing involves the
following steps:
1 Create and configure two or more VLANs.
Although it is possible to enable IP forwarding and an IP
routing protocol (such as RIP) with only one VLAN defined,
the switch does not create or respond appropriately to ICMP
messages unless at least two VLANs are created and
configured.
2 Assign each VLAN that will be using routing an IP address,
using the following command:
config vlan <name> ipaddress <ipaddress>
{<mask>}
Ensure that each VLAN has a unique IP address.
3 Configure a default route, using the following command:
config iproute add default <gateway> {<metric>}
{unicast-only | multicast-only}
Default routes are used when the router has no other
dynamic or static route to the requested destination.
4 Turn on IP routing for one or all VLANs, using the following
command:
enable ipforwarding {vlan <name>}
5 Turn on RIP or OSPF using one of the following commands:
enable rip
enable ospf
Verifying the IP Unicast Routing Configuration
Use the
show iproute
command to display the current
configuration of IP unicast routing for the switch, and for each
VLAN. The
show iproute
command displays the currently
configured routes, and includes how each route was learned.
