Problem changing default route on FMC6.2

HI everyone i have a problem when i try to change the default route on the FMC i go to System->Configuration->Managment Interface and i set the DG but after saving the changes i keeps with the old DG

I also try to change in the linux console removing and adding de new one but i doesnt work.

sudo ip route add 0.0.0.0/0 via 172.xxx.xxx.xxx

sudo ip route del 0.0.0.0/0 via 172.xxx.xxx.xxx

After applying this lines if i do a traceroute it doesn't do anything like if no DG was configured. How can change it or run again the setup process on the FMC?

Thanks and best regards.

If you want to change it from the cli, the supported method is to run:

sudo /usr/local/sf/bin/configure-network
