[c-nsp] GSR E2 LC microcode bundle

[Sorin CONSTANTINESCU]

Hi, all.

I have a Cisco 12008 router running 12.0(30)S4 with 1 x
4OC12/POS-IR-SC-B (E2), and 1 x 3GE-GBIC-SC (E2). This router is part
of our MPLS network. The ingress interface is one of the STM-4
interfaces, and the egress (from this PE router) is a dot1q subif on
one of the GIGE ports.

When pushing traffic out the GIGE subif, the next router (P) makes a
lookup in the default routing table, instead of using the VRF
routing-table. This is very odd, since "show ip cef vrf CustA 1.2.3.4"
shows 2 labels imposed.

However, traffic from the GRP (traceroute/ping inside the CustA vrf)
is correctly label-switched.

The microcode bundle loaded is BUNDLE_pos_vanilla which should have
support for MPLS VPN:

=== cut here ===
LC-Slot2>show controller psa bundle-manager bundle 0
-- Microcode bundle: -------------------------
BUNDLE_pos_vanilla
-- This bundle supports: ---------------------
  Basic IP                          Configured
  Basic MPLS                        Configured
  IPv6 throttling                   Configured
  Multicast throttling              Configured
  MPLS VPN                          Configured
  CsC
  Sampled Netflow
  MPLS Aware Sampled Netflow
  Per Packet Loadbalancing
  L2TPv3

When using "rate-limit input" on the POS interface, the router changes
the bundle on the ASIC to POS: PIRC:

=== cut here ===
SLOT 2:Dec 19 15:26:40: %LC-6-PSA_UNLOAD_UCODE: Unloading
(BUNDLE_pos_vanilla) bundle from the PSA
SLOT 2:Dec 19 15:26:40: %LC-6-PSA_LOAD_UCODE: Loading (POS: PIRC)
bundle into the PSA
SLOT 2:Dec 19 15:26:40: %LC-6-PSA_UCODE_NO_SUPPORT: Current bundle
does NOT support (IPv6 throttling)
SLOT 2:Dec 19 15:26:40: %LC-6-PSA_UCODE_NO_SUPPORT: Current bundle
does NOT support (Multicast throttling)
SLOT 2:Dec 19 15:26:40: %LC-6-PSA_UCODE_NO_SUPPORT: Current bundle
does NOT support (MPLS VPN)
=== and here ===

this bundle doesn't have support for MPLS VPN, and switches the
packets on the LC CPU.

=== cut here ===
LC-Slot2>show controller psa bundle-manager bundle 2
-- Microcode bundle: -------------------------
POS: PIRC
-- This bundle supports: ---------------------
  Basic IP                          Configured
  Basic MPLS                        Configured
  Multicast
  CoS Transparency
  PIRC                              Configured
LC-Slot2>
=== and here ===

While doing this helps achieving the goal of the setup, i have a
problem with the CPU on this linecard getting loaded.

Any hints?

TIA
