Cisco's basic configuration instance of the five----switch routing features and DHCP capabilities

5 , configuring the routing capability of the switch

Note: Routing is only available on a three-layer switch, and other two-tier access switches are not allowed to transfer data between different VLANs until the routing is switched through the trunk port to the core switch .

TEST (config) #ip Routing # enables the routing function of the three layer switch, which is turned off by default

TEST (config) #ip Route 0.0.0.0 0.0.0.0 172.16.0.1

# Configure the default route for the switch, which is the total egress route.

Test (config) #end # Exit Verify the configuration you just made
