Chapter 11
Configuring ATM Routing and PNNI
Basic PNNI Configuration
Summary addresses other than defaults must be explicitly configured on each node. A node can have
multiple summary address prefixes. Note also that every node in a peer group that has a potential to
become a peer group leader (PGL) should have the same summary address lists in its parent node
configuration.
Note
The
no auto-summary
command removes the default summary address(es). Use the
no auto-summary
command when systems that match the first 13-bytes of the ATM address(es) of your switch are attached
to different switches.
To configure the ATM PNNI summary address prefix, perform these steps, beginning in global
configuration mode:
Example
The following example shows how to remove the default summary address(es) and add summary
address 47.009181005670:
Switch(config)#
atm router pnni
Switch(config-atm-router)#
node 1
Switch(config-pnni-node)#
no auto-summary
Switch(config-pnni-node)#
summary-address 47.009181005670
