.. c:type:: struct ls_prefix

.. c:type:: struct ls_ted
|
||||
|
||||
TED stores Vertex, Edge and Subnet elements with a RB Tree structure.
|
||||
The Vertex key corresponds to the Router ID for OSPF and ISO System ID for
|
||||
IS-IS. The Edge key corresponds to the IPv4 address, the lowest 64 bits of
|
||||
the IPv6 address or the combination of the local & remote ID of the interface.
|
||||
The Subnet key corresponds to the Prefix address (v4 or v6).
|
||||
|
||||
Functions
|
||||
^^^^^^^^^
|
||||
An additional status for Vertex, Edge and Subnet allows to determine the state
|
||||
of the element in the TED: UNSET, NEW, UPDATE, DELETE, SYNC, ORPHAN. Normal
|
||||
state is SYNC. NEW, UPDATE and DELETE are temporary state when element is
|
||||
processed. UNSET is normally never used and ORPHAN serves to identify elements
|
||||
that must be remove when TED is cleaning.
