[c-nsp] ASR9K - PLATFORM-NP-3-OOR Error

[Emanuel Popa]

Hi everybody,

We've recently replaced a Cisco 7600 (LAN cards) with a Cisco ASR9K
(Low-queue cards). Everything looks good except for the error below:

LC/0/1/CPU0:Oct 31 20:49:15.113 : prm_server[278]: %PLATFORM-NP-3-OOR
: Routing Table Full : PRM failed to install a route
(188.xxx.xxx.xxx/32) because the subtree  was full. Each subtree is
limited to 131072 routes per subtree.Subtree where install failed is
188.0.0.0/8

We are using Cisco IOS XR Software, Version 4.1.1.

ErrorDecoder at Cisco says:

%PLATFORM-NP-3-OOR: [chars]
Network Processor Provisioning experienced an Out-of-resource
condition that could not be reported back to provisioning agent for
recovery/back-off Loss of configuration and data could occur.
Recommended Action: Loss of configuration and data could occur.
Revisit recent provisioning or route-update events to see if router
resources have been exceeded.

WTF? Does this mean that the RIB hashing function does not support
more than 131072 routes (/15) from the same /8 subnet? No such problem
on the previous router (Cisco 7600)!

Manu
