I have setup my loopback, it works fine. I let the SRX allocate the address for starters
just to see what it produced. This is fine because it is best to let loopback do its own
work as far as the SRX is concerned. This question is only about the address it alots
by itself. It isnt about what i have added.
fe80::2a8a:1c0f:fc40:1500
I want to make the address that it allocates automatically, into a static address, for obvious reasons.
My question is this.
Is the prefix a /64 , /128 or what? Im not worried about a real detailed explanation but
i'd like to know how it decides this. Is it route driven(/64)? My config is all /64 except
where /128 is needed such as ndp-proxy and others. Is it loopback(64 or higher) driven?
It isnt a /128 most likely because the default loopback ipv6 is obviously ::1/128 .
Here is my output....
It is the second to last line in the command output.
It is a local address on the SRX.
