[CentOS] NetworkManager default route

Hello,

Why is it so, that NetworkManager allows, and in several cases I've had, 
defaults to setting default route to several interfaces at the same time?

Had my fair share of problems with how 172.17.62.something interface 
tries to ask for a DHCP lease from 193.something network. I know I could 
set never-default to the interfaces, but I shouldn't have to do it to 
every machine I had.

Especially bad was the situation when I had two VLANs and a normal 
ethernet interface, and dhclient tried to ask a lease for the ethernet 
over the VLAN.

Best regards,
