Typedef Documentation

typedef u32 epg_id_t

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.

typedef int(* gbp_contract_cb_t) (gbp_contract_t *gbpe, void *ctx)

Definition at line 124 of file gbp.h.

typedef struct gbp_contract_key_t_ gbp_contract_key_t

The key for an Contract.

typedef struct gbp_contract_t_ gbp_contract_t

A Group Based Policy Contract.

Determines the ACL that applies to traffic pass between two endpoint groups

typedef int(* gbp_endpoint_cb_t) (gbp_endpoint_t *gbpe, void *ctx)

Definition at line 79 of file gbp.h.

typedef struct gbp_endpoint_key_t_ gbp_endpoint_key_t

The key for an Endpoint.

typedef struct gbp_endpoint_t_ gbp_endpoint_t

A Group Based Policy Endpoint.

This is typcially a VM on the local compute node for which policy must be locally applied
