| Description | The current state of snapshot routing for this entry.
active means that routing information may be exchanged.
quiet, only present on a client snapshot interface,
means that routes are frozen, and that no routing
information may be exchanged until the active state is
reentered. serverPostActive, only present on a server
snapshot interface, means that the active period has
expired, but routing information will still be accepted
from (but not sent to) the associated client router.
transitionToQuiet, and transitionToActive, only present
on a client, are temporary states entered after the active
state, wherein any down to up transition of the interface
will cause a move to the quiet or active state, respectively.
limbo is a temporary state for activity blocks that
are in the process of being created or destroyed. |
