NETGEAR 7000 Series Managed Switch Administration Guide Version 7.2
7-2 IP Routing Services
v1.0, May 2008
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
which is to participate in 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 may 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.
