Configuring the Link Between Switch T3 and Switch T4 for PNNI
The following example shows how to configure the link between switch NewYorkBldB.T3 and
SanFran.BldA.T4 for PNNI.
Note In this example, only one side of the IISP interface is configured to change the link from IISP to PNNI
because the other side of the link is using ILMI autoconfiguration for the interface type. You can use
either the atm auto-configuration or atm nni command to change the link from IISP to PNNI.
SanFran.BldA.T4# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
SanFran.BldA.T4(config)# interface atm 0/0/3
SanFran.BldA.T4(config-if)# atm auto-configuration
SanFran.BldA.T4(config-if)# end
SanFran.BldA.T4#
%ATM-5-ATMSOFTSTART: Restarting ATM signalling and ILMI on ATM0/0/3.
Note When you change the link from IISP to PNNI, all existing connections across the interface are cleared.
The ability to route new connections across the link is r estored within a few seconds, when the PNNI
uplinks and induced horizontal link come up.
Verifying Connectivity to All ATM Addresses and Deleting an Old Static Route on Switches T4 and T3
The following example shows how to verify connectivity to all ATM addresses before deleting an old
static route on switch T4:
SanFran.BldA.T4# show atm route
