Struct LabeledNlriConfig 

pub struct LabeledNlriConfig {
    pub add_path: bool,
    pub mode: LabeledNlriMode,
    pub max_labels: u8,
    pub peer_max_labels: Option<u8>,
}

Configuration for parsing labeled NLRI

Fields

add_path: bool

ADD-PATH enabled (RFC 7911). When true, parse 4-byte path_id before each NLRI.

CRITICAL: ADD-PATH cannot be autodetected from NLRI bytes alone. If ADD-PATH is present on wire but this is false, the path_id bytes will be misinterpreted as NLRI length, causing complete stream desynchronization. The caller MUST configure this correctly based on session state.

mode: LabeledNlriMode

RFC 8277 parsing mode (§2.2 SingleLabel vs §2.3 MultiLabel)

max_labels: u8

Maximum label stack depth for DoS protection. RFC 8277 allows up to 254 (255 means unlimited). Range: 1..=254

peer_max_labels: Option<u8>

Peer-negotiated maximum labels from Multiple Labels Capability. If set and mode is MultiLabel, enforce this limit per RFC 8277 §2.1. Receiving more labels than advertised produces a treat-as-withdraw error. None means no peer limit (use local max_labels only).

Implementations

impl LabeledNlriConfig

pub fn try_new( add_path: bool, mode: LabeledNlriMode, max_labels: u8, peer_max_labels: Option<u8>, ) -> Result<Self, LabeledNlriConfigError>

Create a new config with validation. Returns Err if max_labels is 0 or >254, or if peer_max_labels is Some(0). Note: per RFC 8277 §2.1, peer_max_labels of 1 is accepted (only 0 is forbidden).

Trait Implementations

impl Clone for LabeledNlriConfig

fn clone(&self) -> LabeledNlriConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LabeledNlriConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LabeledNlriConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for LabeledNlriConfig

fn eq(&self, other: &LabeledNlriConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
