Abstract

TCPIP-INCORROUT IPV6 SUBNET FILTER RULE MAY USE INCORRECT MASK

Error Description

When an IPv6 subnet is defined with a prefix length that's not a
multiple of 8, the prefix length is rounded down to a multiple  
of 8, causing the subnet to reference a larger range of        
addresses than desired.                                        
                                                               
Also, displaying active filter rules through IBM Navigator for i
omits all rules based on an IPv6 range or subnet.              

Problem Summary

When an IPv6 subnet is defined with a prefix length that's not a
multiple of 8, the prefix length is rounded down to a multiple  
of 8, causing the subnet to reference a larger range of        
addresses than desired.                                        
                                                               
Also, displaying active filter rules through IBM Navigator for i
omits all rules based on an IPv6 range or subnet.              

Problem Conclusion

IPv6 prefix length processing by filter rules has been          
corrected. Display of active packet filter rules for IPv6 ranges
and subnets has also been corrected.
