Port Routing Configuration

The 7000 Series Managed Switch always supports Layer 2 bridging, but Layer 3 routing must 
be explicitly enabled, first for the 7000 Series Managed Switch as a whole, and then for each 
port that is to be part of the routed network. 

The configuration commands used in the example in this section enable IP routing on ports 
1/0/2,1/0/3, and 1/0/5. The router ID will be set to the 7000 Series Managed Switch’s 
management IP address, or to that of any active router interface if the management address 
is not configured. 

After the routing configuration commands have been issued, the following functions will be 
active:

IP forwarding, responsible for forwarding received IP packets.

ARP mapping, responsible for maintaining the ARP Table used to correlate IP and MAC 

addresses. The table contains both static entries and entries dynamically updated based 
on information in received ARP frames.

Routing Table Object, responsible for maintaining the common routing table used by all 

registered routing protocols. 

You can then activate RIP or OSPF, used by routers to exchange route information, on top of 
IP Routing. RIP is more often used in smaller networks, while OSPF was designed for larger 
and more complex topologies.

The following figure shows a Layer 3 switch configured for port routing. It connects three 
different subnets, each connected to a different port.
