-     If a Path message contains multiple EXPLICIT_ROUTE objects, only the

-     ignored and SHOULD NOT be propagated.
-
-     In current implementation, only strict hops are supported. So,
-     empty ERO with no sub-objects is considered illegal.

-      L
-
-         The L bit is an attribute of the subobject.  The L bit is set
-         if the subobject represents a loose hop in the explicit route.
-         If the bit is not set, the subobject represents a strict hop in
-         the explicit route.
-
-      Type
-
-         The Type indicates the type of contents of the subobject.
