This scenario requires a single track, which will test whether the connection
exists to at least one of the FTP servers. If the track fails, it removes the
primary route to the headquarters. The ISDN connection initiates the next time
that interesting traffic (which you could define as any traffic or as traffic
destined to the FTP servers) arrives on the demand interface. See Figure 9-6.
