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

Functions

func NewSRv6VppHandler

func NewSRv6VppHandler(c vpp.Client, ifIdx ifaceidx.IfaceMetadataIndex, log logging.Logger) vppcalls.SRv6VppAPI

NewSRv6VppHandler creates new instance of SRv6 vppcalls handler

Types

type SRv6VppHandler
