Verifying the OSPF configuration for R3

The following example shows the output of the show ip route command for R3. The output shows that routes to 10.0.0.1/32, 10.0.0.2/32, 10.0.20.0/24, 10.0.30.0/24, and 10.0.40.0/24 have been learned through OSPF (and are the selected routes). The 10.0.0.3/32, 10.0.50.0/24, and 10.0.60.0/24 networks are directly connected to R3. Directly connected routes are always preferred over OSPF-discovered routes.

vyatta@R3:~$ show ip route
Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP
       O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       L - LDP, V - RSVP-TE, I - IGP shortcut
       > - selected route, * - FIB route, p - stale info

The following commands ping IP addresses of hosts in networks connected to R1. Pinging these hosts confirms that the OSPF configuration is working and that you can reach a remote network.
