Interface Backup in Active/Standby Mode

Interface Backup in Active/Standby Mode

As shown in Figure 2-3, the enterprise egress gateway RouterA connects to the Internet through ADSL interface ATM3/0/0. To ensure that enterprise users can connect to the IP network when the ADSL interface is faulty, the link of a 3G interface is used as the backup link. When the active interface is faulty, the backup link is started to transmit services.
