NOTE
In this example, Switch A and Switch B provide access services for users. On live networks, Optical Line
Terminals (OLTs), Digital Subscriber Line Access Multiplexers (DSLAMs), Multi-service Access Nodes
(MSANs), or x Digital Subscriber Line (xDSL) devices can also be used to provide access services for
users. The configuration is similar on Router A, Router B and Router C.
Establish an ICMP NQA test instance for the NQA client Router B and the tested device
Switch A to test whether the active link of Router B → Switch A works properly.
Configure static routes on Router B and Router C, and associate the static route on
Router B with the NQA test instance. If the NQA test instance detects a link fault, the
system deletes the static route from the IP routing table.
Configure a dynamic routing protocol on Router A, Router B, and Router C to allow them
to learn routes from each other.
Configure OSPF on Router B and Router C to import static routes, and set a higher cost
for the static route imported to Router C than that imported to Router B. After Router A
