Cisco Cisco IOS Software Release 12.2(4)B

When you are running multicast in an NRP-2 configuration, the NRP-2 should have 512 MB of memory.

In most NRP-1 configurations, 64-MB DRAM is adequate for up to 750 sessions. If you have more 
sessions, you need 128-MB DRAM. If you are using the NRP-1, for an upgrade from an earlier release 
to Cisco IOS Release 12.2(4)B5, 128-MB DRAM is recommended.

Cisco IOS Release 12.2(4)B5 supports the Cisco 6400 NRP-1, NRP-2, NRP-2SV, NSP, and NSP-S3B 
modules. The NSP-S3B, otherwise identical to the NSP, is required if you want to use the Building Integrated 
Timing Supply (BITS) Network Clocking software feature.

For NRP-Service Selection Gateway (SSG) users, Cisco IOS Release 12.2(4)B5 works with the 
Cisco Service Selection Dashboard (SSD) Releases 2.5(1) and 3.0(1), and Subscriber Edge Services 
Manager (SESM) Release 3.1(1).

To determine the version of Cisco IOS software currently running on the Cisco 6400 NRP, log in to the
