Juniper POLICY MANAGEMENT - CONFIGURATION GUIDE V11.1.X Configuration Manual page 131

With the IP policy forward rule, when more forward rules are added to an existing
classifier group, the list of forward rules is created. This is also true during merging,
as in the following example:
Combining p1, p2, and p3, internally results in the following:
Policy management enables multiple policy attachments at the same attachment
point, which results in a merged policy that is created and attached at the specified
attachment point. The logical OR of the statistics and baseline keywords of all
attachments are used as the statistics and baseline keyword for the merged policy
attachment, as in the following example:
Results in the following:
Merged Policy Naming Conventions
Merged policies are dynamically created. The naming convention is mpl_hex_of
internally_generated_policy ID, such as mpl_10. If the newly generated name already
exists, then a sequence number is appended to the new name to make it unique.
The sequence number starts at 1 and increments until the name is unique, such as
mpl_10_2.
