Struct BgpUpdateMessage 

pub struct BgpUpdateMessage {
    pub withdrawn_prefixes: Vec<NetworkPrefix>,
    pub attributes: Attributes,
    pub announced_prefixes: Vec<NetworkPrefix>,
}

BGP Update Message.

Corresponding RFC section: https://datatracker.ietf.org/doc/html/rfc4271#section-4.3

Fields

withdrawn_prefixes: Vec<NetworkPrefix>

Withdrawn prefixes in this update message.

IMPORTANT: Do not access this field directly in order to get all withdrawn prefixes. Some withdrawn prefixes may be present in the AttributeValue::MpUnreachNlri attribute, and will not be included here. Accessing this field directly may cause you to miss IPv6 or multi-protocol prefixes.

Instead, use [Elementor::bgp_update_to_elems] to reliably extract all withdrawn prefixes from the update, or combine this field with prefixes found in the MpUnreachNlri attribute manually.

• RFC4271 Section 4.3: https://datatracker.ietf.org/doc/html/rfc4271#section-4.3
• RFC4760 Section 4: https://datatracker.ietf.org/doc/html/rfc4760#section-4

attributes: Attributes

BGP path attributes.

announced_prefixes: Vec<NetworkPrefix>

Network prefixes that are being advertised in this update message.

IMPORTANT: Do not access this field directly in order to get all announced prefixes. Some advertised prefixes may be present in the AttributeValue::MpReachNlri attribute, and will not be included here. Accessing this field directly may cause you to miss IPv6 or multi-protocol prefixes.

Instead, use [Elementor::bgp_update_to_elems] to reliably extract all announced prefixes from the update, or combine this field with prefixes found in the MpReachNlri attribute manually.

Implementations

impl BgpUpdateMessage

pub fn encode(&self, asn_len: AsnLength) -> Bytes

pub fn is_end_of_rib(&self) -> bool

Check if this is an end-of-rib message.

https://datatracker.ietf.org/doc/html/rfc4724#section-2 End-of-rib message is a special update message that contains no NLRI or withdrawal NLRI prefixes.

Trait Implementations

impl Clone for BgpUpdateMessage

fn clone(&self) -> BgpUpdateMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BgpUpdateMessage

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

Formats the value using the given formatter.

impl Default for BgpUpdateMessage

fn default() -> BgpUpdateMessage

Returns the “default value” for a type.

impl From<&BgpElem> for BgpUpdateMessage

fn from(elem: &BgpElem) -> Self

Converts to this type from the input type.

impl From<BgpUpdateMessage> for BgpMessage

fn from(value: BgpUpdateMessage) -> Self

Converts to this type from the input type.

impl PartialEq for BgpUpdateMessage

fn eq(&self, other: &BgpUpdateMessage) -> 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.
