How do I view the routing table


To view the current routing table run "netstat -r" or "netstat -rn".

        $ netstat -r 
        Destination        Gateway            Flags    Use Interface  Pmtu
        default            localhost          U          0 lo0        8232
        localhost          localhost          UH         0 lo0        8232

        local              localhost          U          0 lo0        8232
        ssd-net            felix              U          2 cnd00      1500

        default            cisco7206_36       UG         0 cnd00      1500

        $ netstat -rn

        129.134.34.0       129.134.34.18      U          2 cnd01      1500
        *                  129.134.36.196     UG         0 cnd00      1500

The -n option disables name lookup so the Destination and Gateway fields
appear as IP addresses.

Note:
If name lookup is slow or broken then it is much quicker to run netstat -rn.
