Which configuration gets deleted when you perform the command: delete interfaces xe-0/1/5 unit 0 family inet6 address 2001:db8:1:2::1/64?

When executing the command to delete a specific IPv6 address from an interface configuration, the focus is on removing the address associated with that interface unit. In this case, the command explicitly targets the address 2001:db8:1:2::1/64 assigned to the inet6 family within the unit 0 of interface xe-0/1/5.

This command does not affect other components such as the interface itself, family types (like inet or inet6), or the unit configuration as a whole. Instead, it performs a precise action of deleting just that specific address while leaving the broader structure intact. Hence, the answer highlights that the specific IPv6 address is the element being removed during this operation.
