Global Topology Nodes
Use the following command to show the global topology nodes in a tabular form.
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.
Command:
M15-155s8:/>route pnni topology node [<level>]

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 
Branching 
Indicates whether the node can branch point-to-multipoint 
calls. This attribute is resource related.
Non-transit for 
PGL Election
Indicates whether the node is ignored when computing 
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
