Chapter3 Basic NRP Configuration

Transferring an NRP-1 Configuration to an NRP-2 or NRP-2SV

This section describes how to properly transfer an existing NRP-1 configuration to an NRP-2 or

NRP-2SV. Unless a clear distinction is made, all references to the NRP-2 also apply to the NRP-2SV.

Complete the following steps:

Step 1 Copy the existing NRP-1 configuration to a location where you can edit the file:

Router# copy flash:my.cfg tftp://10.1.1.1/my.cfg

Step 2 Edit the configuration file so that:

a. All VPI and VCI values are accepted by the NRP-2 default ranges (VPI range is 0–15, and VCI range

is 0–1023).

b. The ATM MTU settings are less than 1900 bytes and match the MTU settings on the network

neighbors.

This edited file is the new NRP-2 configuration file.

Step 3 In the NSP configuration, remove all VCs to the NRP-1 that you are replacing.

Step 4 From the NSP, copy the NRP-2 configuration to the appropriate slot directory in the PCMCIA disk in

NSP disk slot 0. Make sure that the filename is “nrp2-startup-config.”

Switch# copy tftp://10.1.1.1/my.cfg disk0:/slot4/nrp2-startup-config

Step 5 Verify that:

a. The NRP-2 image is in the desired location.

b. The NSP is configured to boot the NRP-2 image.

For details, see the “Configuring NRP-2 Image Management on the NSP” section on page2-20.

Step 6 On the NRP-1, shut down the ATM interface.

Router(config)# interface atm 0/0/0

Router(config-if)# shutdown

Step 7 Remove the NRP-1 from the Cisco 6400 chassis, and replace it with the NRP-2.

Step 8 On the NSP, reconfigure the VCs that you removed in Step 3.

Step 9 If the NRP-2 did not boot upon insertion, reload the NRP-2 from the NSP.

Switch# hw-module slot 4 reset

Permanent Virtual Circuits

Permanent virtual circuits (PVCs) are used to connect the NRP to the ATM interfaces of the NSP and

node line cards (NLCs) in the Cisco 6400 chassis. Typically, each subscriber is bound to a specific NRP

and should be configured as a separate PVC.

Note Soft VCs between the NRP and NSP are not supported.
