-- Snapshot routing provides easy solutions to two common problems:
--
-- 1) The need to configure static routes for Dial on Demand Routing (DDR)
-- interfaces.
--
-- 2) The overhead of periodic updates for routing protocols to remote
-- branch offices over dedicated serial lines.
--
-- When snapshot routing is configured on an interface, it first allows
-- normal routing updates to be sent across the interface for a short
-- period of time. After this user configured period of activity, the
-- routing updates are suspended, and the routes learned on the snapshot
-- interface are 'frozen' in place, putting the interface into a 'frozen
-- period', again user configurable. During this 'frozen' time, changes
-- in network topology are typically not transmitted across the snapshot
-- interface, although some network protocols provide the capability to
-- transmit changes.
--
-- The factors to consider in choosing to enable snapshot routing to an
-- interface are:
--
-- 1) The importance of obtaining quick notification of changes in the
-- network topology at a remote site.
-- 2) Whether or not you are using Dial on Demand routing from a remote
-- site to reach a central site or using a dedicated serial link.
--
-- If you are using a dedicated serial link, and wish to have
-- up-to-the-minute topology information at a remote site, then snapshot
-- routing is probably not appropriate for you. If, however, the network
-- topology changes less frequently, or if full connectivity to all
-- locations is not important to you, then snapshot routing (with
-- possibly, a few static routes to 'key' remote locations that should
-- always be available) will probably meet your needs well.
--
-- If you are using dial on demand routing (DDR), then Snapshot routing
-- is almost certainly an advantage. Before Snapshot routing, all
-- 'desired' destinations needed to be configured with static routes.
-- With Snapshot routing, it is possible to learn the set of remote
-- routes dynamically, and then keep them available while the link is
-- down, avoiding the configuration of any static routes. Again, if there
-- are 'crucial' locations that must always be in the table, it may be
-- best to configure them statically, to ensure constant availability, in
-- case the desired location was temporarily down when the Snapshot route
-- sharing activity was taking place.
--
-- Snapshot routing is configured on a 'client/server' basis. One router
-- on the interface is chosen as the 'client' router, and it determines
-- active route-exchange and 'sleeping' times.

DESCRIPTION
"Forces the snapshot state to active for all entries
of the ciscoSnapshotActivityTable whose
ciscoSnapshotIfIndex value is specified as parameter.
The interface associated with ciscoSnapshotIfIndex
must be a client interface.
Retrieval of this object will return the value of the
ciscoSnapshotIfIndex that was last forced into the
active state, or 0 if no interfaces have been forced into
the active state since the router was reset"

SYNTAX CiscoSnapshotInterfaceEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A Snapshot Routing configuration entry.
A management station wishing to create an entry should
create the associated instance of the row status object.
It should also modify, either in the same or in successive
PDUs, the values for the other objects if the defaults are
not appropriate.
Once the appropriate instance of all the configuration
objects have been created, either by an explicit SNMP
set request or by default, the row status should be set
to active to initiate the request. Note that this entire
procedure may be initiated via a single set request which
specifies a row status of createAndGo.
In order to prevent inactive (notReady, or notInService)
entries from clogging the table, entries will be aged out,
but an entry will never be deleted within 5 minutes of
creation."

SYNTAX Integer32
UNITS "minutes"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The amount of time to wait and retry a route exchange if an
active period elapses with no routes being exchanged. For
example, if an interface is down (or a DDR phone number is
busy, or a DDR interface is unavailable) during the active
interval, instead of waiting for the amount of time specified
by ciscoSnapshotQuietTime to elapse before an attempt is made
to exchange routing updates again, the attempt is made after
the amount of time specified by this object has elapsed.
This value is calculated automatically based on the
ciscoSnapshotActiveInterval.
An instance of this object may only be present if the value
of the associated ciscoSnapshotClient object is true."

MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object controls the action that takes place when the
interface associated with this entry transitions to the `up'
state while snapshot routing on the interface is in quiet
mode.
A value of goActive will cause the immediate transition to
the active state.
A value of noAction will cause no such transition. Instead,
the transition to the active state will occur normally when
the current quiet period has expired.
Going active immediately incurs extra routing protocol
overhead, but allows a fresh set of routing updates be
exchanged each time the line is brought up. This is useful
in a Dial-on-Demand routing environment.
An instance of this object may only be present if the value
of the associated ciscoSnapshotClient object is true."

Note that if the associated row in the

in this table will only be present when the server is
actively involved in snapshot routing updates."

MAX-ACCESS read-only

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."

DESCRIPTION
"The amount of time during the last active state, in
which protocol exchanges occurred. The minimum time required
to allow updates to be exchanged for a 'successfull update
cycle' is the greater of 3 minutes, or 1/2 the active time.
If the ciscoSnapshotExchangeTimer is less than this, the

ciscoSnapshotDialerMap OBJECT-TYPE

DESCRIPTION
"An array of bits that indicates whether or not routing
information has been exchanged for all protocols. The
most significant bit of the first octet represents the
protocol associated with CiscoNetworkProtocol value of 0;
the least significant bit of the first octet represents
the protocol associated with CiscoNetworkProtocol value
of 7; the most significant bit of the second octet
represents the protocol associated with the
CiscoNetworkProtocol value of 8; and so forth.
Routing information for a given protocol has been exchanged
if the associated bit is set.
