Creating a loopback interface

We can configure a loopback interface on each Hub. Both interfaces will have the same IP address, which can be used as a health-check server. As a result, we can configure just a single health-check server, while in fact the probes will be reaching different Hubs.

To create a loopback interface to use as a health-check server:

config system interface

edit "lo-HC"

set vdom "root"

set vrf 1

set ip 10.200.99.1 255.255.255.255

set allowaccess ping

set type loopback

next

end
