4.3.2.BASE

Description (partial)

Symptom:

When adding members to IPv4/IPv6 object-group, the following
error appear for each member being added:

!!% 'obj_group' detected the 'warning' condition 'Inconsistent address and prefix length. Address may not have bits set beyond prefix length. '


Conditions:

The error is triggered by a prefix member, when any
of the host bit is not zero. The host vs. network
bits are pursuant to CIDR definitions. Example:

192.168.1.2/16, the "192.168.0.0" is network bits.
"1.2" is the host bits. In this case, "1.2" is the
problem because they are not zero. The acceptable
config is:

192.168.0.0/16

Unless user applies caution, one can easily hit this error
sooner or later. The problem is not about the error. The
object-group feature requires all host bits to be 0. The
problem is that when user types multiple prefix members,
some have the non-zero host bits problem, while others
do not have such problem, but the error appears for all
members. It is therefore confusing to user exactly which
member is the problem. The issue is confounded further
when a large number of prefix members are being added
