+/**
+ * Group Base Policy (GBP) defines:
+ *  - endpoints: typically a VM or container that is connected to the
+ *               virtual switch/router (i.e. to VPP)
+ *  - endpoint-group: (EPG) a collection of endpoints
+ *  - policy: rules determining which traffic can pass between EPGs a.k.a
+ *            a 'contract'
+ *
+ * Here, policy is implemented via an ACL.
+ * EPG classification for transit packets is determined by:
+ *  - source EPG: from the packet's input interface
+ *  - destination EPG: from the packet's destination IP address.
