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
be unreachable are indicated in “General topology
information” on page 124.
