Configure an ADSL Interface as the Backup of an Ethernet Interface
Networking Requirements
As shown in
connects to the IP network through GE0/0/1. The link between GE0/0/1 and the IP network is
used as the primary link, and the link between ATM0/0/0 and the Internet is used as the backup
link.
The company wants to monitor the route status of the primary interface to detect connectivity
of the primary link. When the routing entry of the primary link is deleted or becomes inactive,
a backup link is started to transmit services to reduce the impact of the primary link fault on
service transmission.
