Overview

Configuration and operational state parameters relating to the segment routing. This module defines a number of elements which are instantiated in multiple places throughout the OpenConfig collection of models.

Particularly:

• SRGB+LB dataplane instances - directly instantied by SR.
• SRGB+LB dataplane reservations - instantiated within MPLS and future SR dataplanes.
• SR SID advertisements - instantiated within the relevant IGP.
• SR-specific counters - instantied within the relevant dataplane.

Types

type MplsLabel

type MplsLabel string

MplsLabel represents type for MPLS label value encoding

const (
	// valid at the bottom of the label stack,
	// indicates that stack must be popped and packet forwarded
	// based on IPv4 header
	MplsLabel_IPV4_EXPLICIT_NULL MplsLabel = "IPV4_EXPLICIT_NULL"

	// allowed anywhere in the label stack except
	// the bottom, local router delivers packet to the local CPU
	// when this label is at the top of the stack
	MplsLabel_ROUTER_ALERT MplsLabel = "ROUTER_ALERT"

	// valid at the bottom of the label stack,
	// indicates that stack must be popped and packet forwarded
	// based on IPv6 header
	MplsLabel_IPV6_EXPLICIT_NULL MplsLabel = "IPV6_EXPLICIT_NULL"

	// assigned by local LSR but not carried in
	// packets
	MplsLabel_IMPLICIT_NULL MplsLabel = "IMPLICIT_NULL"

	// Entropy label indicator, to allow an LSR
	// to distinguish between entropy label and applicaiton
	// labels RFC 6790
	MplsLabel_ENTROPY_LABEL_INDICATOR MplsLabel = "ENTROPY_LABEL_INDICATOR"

	// This value is utilised to indicate that the packet that
	// is forwarded by the local system does not have an MPLS
	// header applied to it. Typically, this is used at the
	// egress of an LSP
	MplsLabel_NO_LABEL MplsLabel = "NO_LABEL"
)

type SrDataplaneType

type SrDataplaneType string

SrDataplaneType represents Routing block of SIDs.

const (
	// The entity uses MPLS labels as Segment Identifiers.
	SrDataplaneType_MPLS SrDataplaneType = "MPLS"

	// The entity uses IPv6 prefixes as Segment Identifiers.
	SrDataplaneType_IPV6 SrDataplaneType = "IPV6"
)
