IIJAfs Intelligent Backup consists of a main T1
line (from IIJA) and a backup DSL/Cable/T1 line
from a different ISP
IIJA creates
a GRE tunnel between the IIJA Backbone and CPE
over the ISP's connection.
The router
automatically redirects traffic to the backup
DSL/Cable link should the main T1 line go down.
Global
IP address provided by IIJA is available for customer
use while the backup solution is active.
Failover to the backup solution requires no firewall,
remote VPN or server changes on the clientfs end.
