[f-nsp] ISIS loopback interface configuration

[Christian Bering]

Hi folks,

On a Cisco I'd get my loopback interface into the ISIS routing table by
doing:

router isis
 passive-interface loopback 1

On a Foundry I don't have that option. I seem to be able to choose
between:

A)
interface loopback 1
 ip router isis
 ip address x.y.z.v/32

B)
interface loopback 1
 ip address x.y.z.v/32
!
router isis
 address-family ipv4 unicast
  redistribute connected
!

What is the right (best, preferred, best practice) way of doing it?
