Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information
Enabling the Second Processor on the NPE-G1
• Upgrade the ROMmon. (The minimum ROMmon version is 12.3-4r.T3.)
• Install the enabling software.
Instructions for upgrading ROMmon are in the “Using the upgrade rom-monitor file Command” section
on page 7-64.
The minimum software release for the Broadband L2TP Access Concentrator (LAC), L2TP Network
Server (LNS), and PPP Terminated Aggregation (PTA) is Cisco IOS
Release 12.3(14)YM.
Also see the MPF for Broadband LAC, LNS, and PTA document for minimum memory requirements and
configuration information.
Note Before enabling the second processor, you must have IP routing turned on.
Processor 1 is enabled by default after you install the enabling software. To have all packets forwarded
by processor 0, use the no ip mpf command. To enable processor 1, use the ip mpf command.
Save the running configuration to NVRAM. See the “Copying the Saved Configuration to NVRAM”
section on page 7-52. If you do not save the configuration settings that you created in the router using
configuration mode and the setup facility, your configuration will be lost the next time you reload the
router.
