of the NQA test instance and the backup interface.
2.6.2.2 Configuring Association Between Interface Backup in Active/Standby
Mode and BFD
Background
BFD provides fast fault detection independent of media and routing protocols. It can rapidly
detect faults on the forwarding path between two adjacent routers. As shown in
Issue 01 (2014-11-30)
Configuring routing protocols on the primary link and backup link to ensure connectivity
at the network layer
Configuring an NQA test instance of ICMP on RouterA to detect connectivity of the
primary link. For details, see Configuring an ICMP Test Instance.
NOTE
The NAQ test instance must be ICMP.
Run:
system-view
The system view is displayed.
(Optional) Run:
ip route-static ip-address { mask | mask-length } { nexthop-address | interface-
type interface-number [ nexthop-address ] } [ preference preference | tag
*
tag ] track nqa admin-name test-name [ description text ]
Association between the IPv4 static route of the primary link and an NQA test instance is
configured or route priorities of the primary and backup links are set.
NOTE
l If the primary and backup links use dynamic routes, skip 2.
l If the primary and backup links use static routes, perform
IPv4 static route of the primary link and an NQA test instance or set the route priority of the
backup link to be higher than that of the primary link.
Run:
interface interface-type interface-number
The backup interface view is displayed.
Run:
standby track nqa admin-name test-name
Association between interface backup and NQA is configured.
NOTE
A backup interface can associate with only one NQA test instance, while an NQA test instance can
associate with multiple backup interfaces.
