Constants

const (
	BehaviorEnd    uint8 = iota + 1 // Behavior of simple endpoint
	BehaviorX                       // Behavior of endpoint with Layer-3 cross-connect
	BehaviorT                       // Behavior of endpoint with specific IPv6 table lookup
	BehaviorDfirst                  // Unused. Separator in between regular and D
	BehaviorDX2                     // Behavior of endpoint with decapulation and Layer-2 cross-connect (or DX2 with egress VLAN rewrite when VLAN notzero - not supported this variant yet)
	BehaviorDX6                     // Behavior of endpoint with decapsulation and IPv6 cross-connect
	BehaviorDX4                     // Behavior of endpoint with decapsulation and IPv4 cross-connect
	BehaviorDT6                     // Behavior of endpoint with decapsulation and specific IPv6 table lookup
	BehaviorDT4                     // Behavior of endpoint with decapsulation and specific IPv4 table lookup
	BehaviorLast                    // seems unused, note in VPP: "Must always be the last one"
)

Constants for behavior function hardcoded into VPP (there can be also custom behavior functions implemented as VPP plugins) Constants are taken from VPP's vnet/srv6/sr.h (names are modified to Golang from original C form in VPP code)

const (
	SteerTypeL2   uint8 = 2
	SteerTypeIPv4 uint8 = 4
	SteerTypeIPv6 uint8 = 6
)

Constants for steering type Constants are taken from VPP's vnet/srv6/sr.h (names are modified to Golang from original C form in VPP code)

const (
	AddSRList            uint8 = iota + 1 // Add SR List to an existing SR policy
	DeleteSRList                          // Delete SR List from an existing SR policy
	ModifyWeightOfSRList                  // Modify the weight of an existing SR List
)

Constants for operation of SR policy modify binary API method

Types

type SRv6VppHandler

type SRv6VppHandler struct {
	vpe_vppcalls.VpeVppAPI
	// contains filtered or unexported fields
}

SRv6VppHandler is accessor for SRv6-related vppcalls methods

func NewSRv6VppHandler

func NewSRv6VppHandler(vppChan govppapi.Channel, ifIndexes ifaceidx.IfaceMetadataIndex, log logging.Logger) *SRv6VppHandler

NewSRv6VppHandler creates new instance of SRv6 vppcalls handler

func (*SRv6VppHandler) AddLocalSid

func (h *SRv6VppHandler) AddLocalSid(localSID *srv6.LocalSID) error

AddLocalSid adds local sid <localSID> into VPP

func (*SRv6VppHandler) AddPolicy

func (h *SRv6VppHandler) AddPolicy(policy *srv6.Policy) error

AddPolicy adds SRv6 policy <policy> into VPP (including all policy's segment lists).

func (*SRv6VppHandler) AddPolicySegmentList
