Newbie Question ? How do I discard the changes I made in Routing

[m4st3rc1p0]

I know this is silly to ask but anyway i will still ask this how do i discard the changes i made in routing. I accidentally change the default gateway.

Previous config is it obtains gateway via dhcp is there a way i can discard the changes I already save it but I dont press apply the change to take effect :

** Take note i don't remember what gateway is define since it is dhcp.

Thanks,
