The value of tmnxOspfSuperBackBone specifies whether CE-PE
functionality is required or not. tmnxOspfSuperBackBone indicates the
type of the LSA generated as a result of routes redistributed into
OSPF.
When the value is set to 'true' the redistributed routes are injected
as summary, external or NSSA LSAs.
When the value is set to 'false' the redistributed routes are injected
as either external or NSSA LSAs only.
