4.1.2.MGBL

Description (partial)

Symptom:
When customer issues a command to match ipv4 destination of 239.0.0.0/8, instead of matching destination prefixes with 239 in the first octet, it matches all destination prefixes with 239 in the last octet.

IPV4SrcAddr      IPV4DstAddr      IPV4TOS  
208.85.44.22     97.90.4.239      0        
75.101.155.183   97.93.235.239    0        
199.96.60.1      68.191.222.239   0        
173.236.50.59    71.84.216.239    0        
189.13.28.193    71.92.71.239     0        
50.16.188.64     68.191.215.239   0        
66.102.80.214    66.169.76.239    0        
174.127.96.68    24.176.116.239   0

Conditions:
This issue happens when RP and the linecard are of different architectures (i.e. intel versus ppc). It works fine if both RP and linecard have the same architecture. This is because of different byte ordering of integers between the architectures.
