You should really specify what they have as backup in the first place. There
are many different ways of backing up lines from HQ to branch. Some examples:
On a router you could have serial 0 as the primary and then a lower bandwidth
serial 1 as the backup. To do this, in interface s0 you would place "backup
int s1 0 300". The 300 being the time s1 waits to go back down when it
realizes that s0 came back up.
If you are using HSRP then you would have 2 devices. One would be the active
and the other on standby. All info is passed through the main until it goes
down and then it automatically starts going through the standby which has now
become the active.
These both have much more detail to them but instead of me going into detail,
I'm sure you could just read up on them. The book would be more accurate them
me for sure. Hope I helped...
