The syntax is as follows to add an IPv4/IPv6 address:

ip addr add {ip_addr/mask} dev {interface}

To add a new route, the syntax is:

ip route add {NETWORK/MASK} via {GATEWAYIP}
ip route add {NETWORK/MASK} dev {DEVICE}

## Add default route using ip ##
ip route add default {NETWORK/MASK} dev {DEVICE}
ip route add default {NETWORK/MASK} via {GATEWAYIP}

For example, to Add a plain route to network 192.168.1.0/24 via gateway 192.168.1.254:

ip route add 192.168.1.0/24 via 192.168.1.254
