GBP plugin
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.
