2.7.3 Associating a IPv6 Static Route with an NQA Test Instance
If an IPv6 static route is associated with an NQA test instance, NQA tests the link status
periodically. After NQA detects a fault in the link along the associated static route, the static
route is deleted and traffic diverts to another route.
Context
On a network with a simple topology, configuring static routes allows the network to work
properly. When the router fails to set up a route by using the dynamic routing protocol, you can
configure a static route. Unlike dynamic routing protocols, static routes do not have a dedicated
detection mechanism. Static routes cannot detect faults on the network, which probably causes
traffic loss.
NQA for IPv6 static routes enables a static route to be associated with an NQA test instance.
You can use the ping function of an NQA test instance to detect the status of links of the static
route. Then you can determine whether the associated static route is active and whether traffic
is interrupted.
Perform the following steps on the router:
