IP Unicast Routing

configure vlan <vlan_name> ipaddress <ipaddress> {<ipNetmask>}

Ensure that each VLAN has a unique IP address.

3 Configure a default route using the following command:

configure iproute add default <gateway> {vr <vrname>} {<metric>} {multicast-only |

unicast-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 {[vr <name> | {broadcast} {fast-direct-broadcast}

{ignore-broadcast} {vlan <name>}]}

5 Turn on RIP or OSPF using one of the following commands:

enable ripp

enable ospf

Verifying the IP Unicast Routing Configuration

Use the show iproute command to display the current configuration of IP unchaste routing for the

switch, and for each VLAN. The

show iproute command displays the currently configured routes, and

includes how each route was learned.

Additional verification commands include:

• show bootprelay—Displays the IP ARP table of the system.

• show ipconfig—Displays configuration information for one or more VLANs.

Routing Configuration Example

Figure 31 illustrates a BlackDiamond switch that has three VLANs defined as follows:

• Finance

— All ports on slots 1 and 3 have been assigned.

— IP address 192.207.35.1.

• Personnel

— Protocol-sensitive VLAN using the IP protocol.

— All ports on slots 2 and 4 have been assigned.

— IP address 192.207.36.1.

• MyCompany

— Port-based VLAN.

— All ports on slots 1 through 4 have been assigned.
