Second proposal (3)
autnum class
- option would be to define import6 and export6 attributes inside the object.
-
- Separates policy items for different address families
- Is more clear for humans
- existing tools are not faced with unexpected data
Pitfall:
- May require duplication of policy if it is your IPv4 and IPv6 policies are the same
- Is less elegant from a pure language perspective
Other classes
- would follow the same pattern as for classes above
