Changing existing route entry

Note: When entered in the Ethernet TAP probe, static routes are not updated automatically. You must update these routes if changes in network topology affect the static routes.

Before entering static routes, make a map of all gateway paths between the Ethernet TAP probe, as starting point, and each workstation that must have access to it.

To change existing routing entry

At the core> prompt, delete the existing routing entry:
```
netparam delete_route host_ip gateway_ip
```
Enter the new route as described above:
```
netparam add_route host_ip gateway_ip hop_#
```
Note: host_ip can identify an individual workstation or a network serving multiple hosts. The gateway_ip is the first gateway the probe traffic crosses when communicating with the destination workstation. The hop_# is the decimal number of gateways between the probe and the destination workstation. For an example of static routing, see the next section.
