rndc reload says zone was found in multiple views

Question

$ sudo rndc reload 15.168.192.in-addr.arpa
rndc: 'reload' failed: multiple
zone '15.168.192.in-addr.arpa' was found in multiple views

It is true. I have the zone in multiple views, so I need to use the [class [view]] params of rndc reload.

What do I put for class?

Answer 1

I finally found the answer in the manual. Class is just IN as in internet zone. BIND supports other things like hesoid and this field specifies that it is an internet zone.

sudo rndc reload 15.168.192.in-addr.arpa IN all

works where all is the name of my view.
