The information in this table is derived from Nodal Info PTSEs received from the nodes in the domain.

If the optional <level> parameter is used, only the nodes of that level shall be displayed.

Field	Description


Orig Node Id	This is the 22 bytes of the node ID.

Leader	Indicates whether the node thinks it is a Peer Group Leader
	(PGL).

Restrict Transit	Indicates if the node advertises itself as restricted transit. If a
	node is restricted transit, no routes can go through that node.
	However, setups to/from end systems connected to that node
	are valid.

Representation	Indicates the way the node is represented. For LGNs, the
	representations may be either ‘simple’ or ‘complex’.

Restrict	Indicates whether the node can branch point-to-multipoint
Branching	calls. This attribute is resource related.

Non-transit for	Indicates whether the node is ignored when computing
PGL Election	connectivity in the PGL Election algorithm. The node is non-
	transit for PGLE when it is operating in overload state.

Reachable	Indicates whether the node is reachable. Reasons for a node to
	be unreachable are indicated in “General topology
	information” on page 124.
