Port Routing

The first networks were small enough for the end stations to communicate directly. As networks grew, Layer 2 bridging was used to segregate traffic, a technology that worked well for unicast traffic, but had problems coping with large quantities of multicast packets. The next major development was routing, where packets were examined and redirected at Layer 3. End stations needed to know how to reach their nearest router, and the routers had to understand the network topology so that they could forward traffic. Although bridges tended to be faster than routers, using routers allowed the network to be partitioned into logical subnetworks, which restricted multicast traffic and also facilitated the development of security mechanisms.

An end station specifies the destination station’s Layer 3 address in the packet’s IP header but sends the packet to the MAC address of a router. When the Layer 3 router receives the packet, at a minimum it does the following:

•

•

•

Looks up the Layer 3 address in its address table to determine the outbound port Updates the Layer 3 header

Recreates the Layer 2 header

The router’s IP address is often statically configured in the end station, although the Unified Switch supports DHCP that allow the address to be assigned dynamically. You may assign static entries in the routing tables used by the router.

Port Routing Configuration

The Unified Switch always supports Layer 2 bridging, but Layer 3 routing must be explicitly enabled, first for the Unified Switch as a whole, and then for each port which is to participate in the routed network.

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

After you’ve issued the routing configuration commands, the following functions are active:

•IP Forwarding - responsible for forwarding received IP packets.
