Assuming the 3G link has higher routing and dns metrics than the ADSL link, no traffic should flow over the 3G link while the ADSL link is up. It's probably worth keeping an eye on this periodically with
{Administrator}=>:ip iflist
because a 3G fallback link where one has accidently run out of PAYG credit or exceeded a monthly usage limit will be of no use at all.
==== "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 (note that a A&A Mobile Data SIM provides a fixed IPv4 address).
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:
