A. Yes, two NRPs can be configured for redundancy as long as they are in adjacent slots. Either NRP can be configured as primary, with the other in redundant fail-over mode. To configure redundancy between two NRP’s, they must be in adjacent odd/even slots In other words, you can configure redundancy across NRP’s in slots 1 and 2 or 3 and 4, but not 2 and 3 or 1 and 4. Cisco IOS Software Release 12.0(3)DC added support for EHSA 1+1 redundancy for the Cisco 6400 Node Route Processor (NRP-1) card. Cisco IOS Software Release 12.2(13)T adds EHSA 1+1 redundancy support for the Node Route Processor 2 with Shaped Virtual Circuits (NRP-2SV).
