I've only seen this in deployments of BNG for the gateway address of the subnets being managed.
I doubt that use case is found in the enterprise.

Subject: Question on Multiple IP addresses on the Same Loopback Sub-interface
Hi.
Why would an Enterprise router's loopback interface ever need multiple IP addresses on a single sub-interface as shown below?
interfaces {
loopback {
family inet {
address 172.16.1.1/32 {
primary;
}
address 172.16.2.1/32;
address 172.16.3.1/32;
address 172.16.4.1/32;
}
}
}
Thanks,
Deepak
