You are adding an IPv6 configuration to an Interface on a Junos device.

In this scenario, which statement is correct?

Show Suggested Answer Hide Answer
Suggested Answer: C

Just to clarify, C is also true since it uses the MAC for address generation.

Wait, is it really automatically created? I thought it had to be set manually.

I thought link local addresses had to be manually configured, but now I'm questioning if they are auto-generated instead.

I'm a bit unsure about the prefix ranges, but I remember that link local addresses are usually tied to the MAC address.

I think the link local address is automatically created, but I can't remember if it's fe80:: or fd00::.
