Configuring ATM Routing and PNNI
Basic PNNI Configuration
Entering the
scope mode automatic
command
ensures that all organizational scope values cover an area
at least as wide as the current node’s peer group. Configuring the scope mode to
manual
disables this
feature and no changes can be made without explicit configuration.
To configure the PNNI scope mapping, perform these steps, beginning in global configuration mode:
Example
The following example shows how to configure PNNI scope mapping manually so that organizational
scope values 1 through 8 map to PNNI level 72:
Switch(config)#
atm router pnni
Switch(config-atm-router)#
node 1
Switch(config-pnni-node)#
scope mode manual
Switch(config-pnni-node)#
scope map 1 8 level 72
