HP-UX: How Do I configure routing or add route?

You can use route command to configure routing. Syntax is as follows:
route add net {network-address} netmask {subnet} {router-address}

Let us assume your router address is and network ID is, then you can type route command as follows:

# route add net netmask


To add a default route:

# route add default

Verify that (display) routing table is updated (display routing table):

# netstat -nr

Test it i.e. try to ping or send nslookup request:

# ping

To flush all routing entries use command :

# route -f

However if I reboot HPUX box then above routing entries gets removed. To pick up your setting upon each reboot your need to configure Routes in HPUX networking configuration file - /etc/rc.config.d/netconf. To add default router/gateway

# vi /etc/rc.config.d/netconf

Add or modify following entries


Reboot HP-UX system/server to take effect

# shutdown -ry 0
