Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing PNNI Nodes
Enabling and Disabling the Complex Node Feature
The complex node feature applies to PGL parent LGNs in MPG networks. When this feature is disabled,
parent LGNs present other peer groups to the child peer group using simple node representation. With
simple node representation, each external peer group is presented as a simple node with a single cost for
routing through the peer group.
When the complex node feature is enabled, a parent LGN presents other peer groups using complex node
representation. Complex node representation provides information about multiple paths through external
peer groups, and this gives source route nodes more choices when routing through external peer groups.
Tip For more information on complex nodes, refer to the Cisco PNNI Network Planning Guide for MGX and
SES Products.
To enable or disable the complex node feature, enter the following command:
mgx8830a.1.PXM.a > cnfpnni-node <node-index > -complexNode on|off
Replace node-index with the index that identifies the logical node you are modifying, and enter either
on or off for the -complexNode parameter. When this parameter is set to on, the node presents external
peer groups using complex node representation. When the -complexNode parameter is set to off, the
node presents external peer groups using simple node representation.
To view the status of the -complexNode option, enter the dsppnni-node command as shown in the
following example:
M8850_LA.8.PXM.a > dsppnni-node
node index: 1 node name: M8850_LA
Level............... 56 Lowest.............. true
Restricted transit.. off Complex node........ on
Branching restricted off
Admin status........ up Operational status.. up
Non-transit for PGL election.. off
Node id...............56:160:47.00918100000000036b5e2bb2.00036b5e2bb2.01
ATM address...........47.00918100000000036b5e2bb2.00036b5e2bb2.01
Peer group id.........56:47.00.9181.0000.0000.0000.0000.00
Enabling and Disabling Routes Through a Node
The restricted transit option allows you to allow or block call routes that pass through the node and
terminate on other nodes. The default setting for this option enables calls to pass through.
To enable or disable PNNI routing through a node, enter the cnfpnni-node command as follows:
mgx8830a.1.PXM.a > cnfpnni-node <node-index > -transitRestricted on|off
Replace node-index with the index that identifies the logical node you are modifying, and enter either
on or off for the -transitRestricted parameter. When this parameter is set to on, the node only accepts
calls that terminate on this node. When the -transitRestricted parameter is set to off, the node accepts
calls that pass through the node and terminate on other nodes.
