Extended Communities.

Overview

It is a 8-octet data that has flexible definition based on the types: https://datatracker.ietf.org/doc/html/rfc4360

For more up-to-date definitions, see IANA’ website.

   Each Extended Community is encoded as an 8-octet quantity, as
   follows:

      - Type Field  : 1 or 2 octets
      - Value Field : Remaining octets

       0                   1                   2                   3
       0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
      |  Type high    |  Type low(*)  |                               |
      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+          Value                |
      |                                                               |
      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

      (*) Present for Extended types only, used for the Value field
          otherwise.

Display

When output, the extended communities has the following string prefixes to indicate the sub type:

• ecas2: stands for Extended Community AS Specific 2-octet
• ecas4: stands for Extended Community AS Specific 4-octet
• ecv4: stands for Extended Community IPv4 Specific
• ecv6: stands for Extended Community IPv6 Specific
• ecop: stands for Extended Community Opaque
• ecraw: stands for Extended Community Raw

Implementations

impl ExtendedCommunity

pub const fn community_type(&self) -> ExtendedCommunityType

Trait Implementations

impl Clone for ExtendedCommunity

fn clone(&self) -> ExtendedCommunity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtendedCommunity

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

Formats the value using the given formatter.

impl Display for ExtendedCommunity

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

Formats the value using the given formatter.

impl PartialEq for ExtendedCommunity

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

This method tests for self and other values to be equal, and is used by ==.

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

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