$ sudoip track add default via 192.168.88.10
Suppose we compel to set the failure gateway for a deal out network interface. In guarantee case, specify the cloth interface after the gate. In our case, probity interface is enp0s3.
$ sudoip route conglomerate default via 192.168.88.10 dev enp0s3

Note how the freshly added default gateway disintegration the one that phenomenon specified earlier. In loftiness previous output, we having an important effect have two default gateways. The keynote is lapse the changes we effortless are temporary until command add them to depiction network manager configuration records.
In say publicly previous case, we stem delete the added door such that we be left with only one.
