set default route interface in iproute2

Question

I have two machines. One runs arch linux and another runs fedora. arch uses iproute2. so i need a conversion for iproute2 from route. this command will set the default interface to ppp0.

I have searched for documentation but I have still no clue.

How shall do this in iproute2

route add default ppp0

ip route add default via 192.0.2.254

You can't specify a device for a route, it has to be an address. Generally you shouldn't have to do this at all; pppd should take care of adding a default route if it is configured appropriately.

I have two NICs, eth0 and ppp0, so i need to bond a default interface. – Idlecool Jul 24 '11 at 12:40
No you don't. Routing doesn't work like that. – womble Jul 24 '11 at 12:41

It's entirely valid to specify a device as a default route. It's only valid when that interface is a point-to-point though. – MikeyB Jul 24 '11 at 14:56
so basically, each line output of `ip route` is syntactically-valid input to `ip route add` (?) – ThorSummoner Oct 02 '17 at 17:09
