(This assumes that the routing metric and dns metric for the ADSL link are both set to 10. Larger numbers represent a higher "cost", so interfaces with lower costs will be preferred).
==== "Dial" on Demand ====
One may not want the 3G link to be permanently up, in which case it is possible to configure the 3G link to be "dial" on demand - i.e. the link will be brought up and torn down as needed when the ADSL link fails and is restored.
This may cause problems for users if the 3G network issues a different IP address each time the link is brought up.
The configuration involves setting the interface to be "dial" on demand; setting a time delay before the link is brought up when needed; setting a time that the link can be idle for before the link is torn down; and deciding how the link is considered idle. The commands needed are:
{Administrator}=>ppp ifconfig intf=mobilebroadband demanddial=enabled
That enables "dial" on demand.
{Administrator}=>ppp ifconfig intf=mobilebroadband doddelay=120 idletime=300 idletrigger=RxTx
where doddelay (in seconds) sets the time delay before packets will bring up the link, idletime (in seconds) sets the time that link can be idle for before being torn down, and idletrigger defines whether link idleness is determined by Rx, Tx, or RxTx packets.
