2. At the command line, type config to enter configuration mode:
> config
(config)>
3. Determine the index number of the static route to be deleted:
(config)> show network route static
0
dst 10.0.0.1
enable true
no gateway
interface /network/interface/lan1
label new_static_route
metric 0
mtu 0
1
dst 192.168.5.1
enable true
gateway 192.168.5.1
interface /network/interface/lan2
label new_static_route_1
metric 0
mtu 0
(config)>
4. Use the index number to delete the static route:

Policy-based routing

Normally, a routing device determines how to route a network packet based on its destination
address. However, you can use policy-based routing to forward the packet based on other criteria,
such as the source of the packet. For example, you can configure the TX40 device so that high-priority
traffic is routed through the cellular connection, while all other traffic is routed through an Ethernet
(WAN) connection.
Policy-based routing for the TX40 device uses the following criteria to determine how to route traffic:
Firewall zone (for example, internal/outbound traffic, external/inbound traffic, or IPSec tunnel
n
traffic).
Network interface (for example, the cellular connection, the WAN, or the LAN).
