www.dell.com | support.dell.com Enabling Routing The S-Series always provides Layer 2 bridging, while Layer 3 routing must be explicitly enabled, first for the S-Series router as a whole, and then for each port that is to participate in the routed network. As introduced in the Getting Started chapter, use the show version command (see Figure 3-8 on page 35) to verify that the Routing package ("Layer 3 Package") of SFTOS is installed in order to utilize these routing procedures. Then, to inspect the system for configured Layer 3 interfaces, use the show ip interface brief command (see Figure 3-16 on page 41). For more details about a specific interface, use the following commands (Note, however, that routing must be enabled before these commands produce a report.): • show ip interface unit/slot/port: See Figure 3-15 on page 40. • show ip interface vlan vlan-ID To view IP information on a Layer 3 interface, use the show ip interface command in the Privileged Exec mode (Figure 17-218). Figure 17-218. show ip interface Command Example Force10 >show ip int vlan 58 Vlan 58 is up, line protocol is up Internet address is 1.1.49.1/24 Broadcast address is 1.1.49.255 Address determined by config file MTU is 1554 bytes Inbound access list is not set Proxy ARP is enabled Split Horizon is enabled Poison Reverse is disabled ICMP redirects are not sent ICMP unreachables are not sent 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 management IP address of the S50 stack, 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. 248 | Layer 3 Routing
