the route destination is presented in another format, such as:
label stacking ( Next-to-the-last-hop routing device for MPLS only) Depth of the Multiprotocol Label Switching
(MPLS) label stack, where the label-popping operation is needed to remove one or more labels from
the top of the stack. A pair of routes is displayed, because the pop operation is performed only when
the stack depth is two or more labels.
Protocol from which the route was learned and the preference value for the route.

Level (IS-IS only). In IS-IS, a single AS can be divided into smaller groups called areas. Routing between
areas is organized hierarchically, allowing a domain to be administratively divided into smaller areas.
This organization is accomplished by configuring Level 1 and Level 2 intermediate systems. Level 1
systems route within an area; when the destination is outside an area, they route toward a Level 2
system. Level 2 intermediate systems route between areas and toward other ASs.
