Association Between Interface Backup in Active/Standby Mode and Routing

Association Between Interface Backup in Active/Standby Mode and Routing

When the upstream indirectly connected link of the primary interface is faulty, the interface backup module cannot detect the fault, causing service interruption. When a link is faulty, the routing entry of the link is deleted or becomes inactive. Association between interface backup and routing enables the system to detect connectivity of the primary link and implement rapid switching when the primary link is faulty. This ensures reliability of service transmission.

Figure 2-7  Networking diagram of association between interface backup and routing

As shown in Figure 2-7, the egress gateway RouterA in the headquarters of company connects to the Internet through GE1/0/0. The link between GE1/0/0 and the Internet is used as the primary link, and the link between ATM0/0/0 (ADSL interface) and the Internet is used as the backup link. Association between interface backup and routing is configured on ATM0/0/0 to detect the route status of the primary link. When the link between RouterD and RouterB is faulty, the routing module detects that the route of the primary link is deleted and instructs RouterA to start ATM0/0/0 to transmit services.
