What is the role of NQA?

The function of H3C's nqa

is mainly used for primary and backup routing to ensure that the line is normal.

1. Networking requirements:

Server can reach the opposite end line through two routers to ensure redundancy and automatic switching when disconnection

2. Actual configuration nqa

nqa is mainly divided into three steps

1. Configure nqa detection.

2. Configure the association between track and nqa.

3. The written static routing associated track

The specific configuration commands are as follows:

1. You need to write nqa related commands on the main router

For example:

nqa entry admin piaojiaosuo Create nqa event group (the name of the line marked as the ticket exchange can be set as required)

type icmp-echo determine the detection method

destination ip 49.100.0.225 specifies the destination address (can be the final destination address or the next hop address)

frequency 100 starts detection after 100 milliseconds of disconnection (starts specified related actions when disconnection exceeds 100 milliseconds) Mainly refers to the next step)

reaction 1 checked-element probe-fail threshold-type consecutive 2 action-type trigger-only Set the trigger condition after the action is detected twice

Quit after completing the above

nqa schedule admin piaojiaosuo start-time now lifetime forever Configure permanent detection

2. Configure track to associate with nqa

For example:

track 1 nqa entry admin piaojiaosuo reaction 1 Let track1 associate with nqa admin piaojiaosuo group and detect actions

3. Write a static route to specify the association with track

Ip routing static 172.31.72.0 24 49.100.0.225 track 1 association completed ( This static route is associated with track1. When the route disappears or becomes unavailable, adjust it according to track1)

4. Static routing needs to write its own routes on the two switches respectively. nqa is only done on the main device
