Configuring the Complex Node Representation for LGNs
By default, higher-level logical group nodes (LGNs) represent their child peer groups (PGs) in the
simple node representation. With simple node representation, the entire peer group is represented as a
single node. When there are many nodes in the child peer group, you can use complex node
representation to present a more accurate model of the PG. With complex node representation, the PG is
represented by a nucleus, or center, and border ports.

To configure complex node representation, perform the following steps, beginning in global
configuration mode:

Example
The following example shows how to configure a PNNI complex node:
Switch(config)# atm router pnni
Switch(config-atm-router)# node 2
Switch(config-pnni-node)# nodal-representation complex
Displaying the PNNI Complex Node Configuration
To display the PNNI complex node configuration, perform the following task in privileged EXEC mode:
Command
Purpose
Step 1
Switch(config)# atm router pnni
Switch(config-atm-router)#
Enters ATM router PNNI mode.
Step 2
Switch(config-atm-router)# node local-node-index
Switch(config-pnni-node)#
Enters node configuration mode and specifies
the local node you want to configure.
the local node you want to configure.
Step 3
Switch(config-pnni-node)# nodal-representation
{simple | complex [threshold threshold-value |
radius-only]}
{simple | complex [threshold threshold-value |
radius-only]}
Configures complex nodal representation and
specifies how to handle exceptions.
