As I understand it, there are two types of ispf:
* ISPF where the LSDB changes are type5 LSA i.e. at the leaves of the
SPF tree, which can be done incrementally. I believe both IOS and JunOS
do this by default?
* the "extra" ispf that the Cisco IOS command does, which applies to
type1/2 LSA changes:
Does JunOS do both or only the former?
