CISCO-ITP-GRT-MIB
AI MIB Summary
The CISCO-ITP-GRT-MIB manages SS7 routing configurations on Cisco IP Transfer Points by exposing route tables, linksets, and routesets for monitoring destination point code (DPC) mappings, linkset priorities, and combined linkset load-sharing states. It enables the verification of Message Signalling Unit (MSU) forwarding logic, including fully-qualified and summary routing entries, to ensure correct path selection and redundancy across IP-based or TDM SS7 networks.
This MIB is for managing information required to route messages transported over Signalling System No. 7 (SS7) Network via Cisco IP Transfer Point.
The Cisco IP Transfer Point (ITP) is a hardware and software solution that transports SS7 traffic using IP. Each ITP node provides the functions necessary to act as a SS7 signalling point. Each signalling point is connected to other signalling point using IP based or traditional TDM links.
The relevant ITU documents describing this technology are the ITU Q series, including ITU Q.700: Introduction to CCITT Signalling System No. 7 and ITU Q.701 Functional description of the message transfer part (MTP) of Signalling System No. 7.
Definitions and overview:
Route:
A route consists of one or more linksets used to transport MTP3 Message Signal Units(MSU) between signalling points. A route is an association between a destination point code(DPC) and a linkset, i.e., a linkset that can be used to send an MSU to the given DPC.
Routeset:
A routeset is a set of routes to a given DPC. Each route within a routeset is on a possible path toward the DPC. Each route within the routeset has associated with it a route priority.
In the following simple configuration, two routes exist that can be used to transport MSUs from STP1 to STP4.
- STP1-STP2 -
- STP1 - STP2 -
- -
| | | STP1-STP3 STP2-STP4 | | |
- STP3-STP4 -
- STP3 - STP4 -
- -
Routeset on STP1 for DPC = STP4: STP1-STP2, STP1-STP3
Linkset:
A linkset is a set of signalling links connecting two signalling points.
Combined Linkset: Two linksets with equal number of links and capacity that form routes of equal priority to a given DPC are called Combined Linksets. It is primarily used for load sharing and redundancy. In the following, example, linksets 'SSP1-STP1' and 'SSP1-STP2' form a combined linsket.

Routing:
The routing of SS7 Message signalling Units(MSU) is based on the DPC. Message Signalling Units are sent from an originating point code(OPC) to DPC. Each MSU will traverse one or more linksets as it is routed to its final destination. When an MSU arrives at a signalling point and the DPC does not match the signalling point's point code the MSU must be directed toward the DPC. Each signalling point has enough routing information to determine which linkset should be used to transmit the MSU toward its final destination.
Route statement: Each ITP Signalling Point has route statements needed to determine which linkset should be used to transmit message signalling units to destinations. Each route statement consists of a destination, a priority and a linkset name. The destination is specified as a combination of DPC and mask. The priority, also know as cost, is used to define the order in which the routes are selected. The linkset name specifies which linkset to use to reach the destination.
Route table: Each ITP Signalling Point has a table of routes. These route entries are used to determine which linkset should be selected to transmit message signalling units to a given destination.
There are two basic type of routing. The first type is fully-qualified and uses all bits of the target DPC. The other type is summary routing that uses a subset of the bits in the target DPC and is used to represent groups of point codes rather than a single point code.

Routing:
The routing of SS7 Message signalling Units(MSU) is based
on the DPC. Message Signalling Units are sent from an
originating point code(OPC) to DPC. Each MSU will
traverse one or more linksets as it is routed to its
final destination. When an MSU arrives at a signalling
point and the DPC does not match the signalling point's
point code the MSU must be directed toward the DPC. Each
signalling point has enough routing information to
determine which linkset should be used to transmit the
MSU toward its final destination.
Route statement:
Each ITP Signalling Point has route statements needed to
determine which linkset should be used to transmit
message signalling units to destinations. Each route
statement consists of a destination, a priority and a
linkset name. The destination is specified as a
combination of DPC and mask. The priority, also know
as cost, is used to define the order in which the routes
are selected. The linkset name specifies which linkset
to use to reach the destination.
Route table:
Each ITP Signalling Point has a table of routes.
These route entries are used to determine which linkset
should be selected to transmit message signalling units
to a given destination.
There are two basic type of routing. The first type
is fully-qualified and uses all bits of the target DPC.
The other type is summary routing that uses a subset
of the bits in the target DPC and is used to represent
groups of point codes rather than a single point code.

cgrtDestStatusList of the possible route state values.
'unknown' : A destination state of unknown
occurs when the destination is a summary route.
Unknown state is presented to indicate the
protocols do not exchange state information for
summary routes in certain configurations.
'accessible' : The destination can be reached by
one or more routes specified for the destination.
When summary routing is enabled, a destination
status will also depend on route table entries that
specify less specific matches. See Example 4 in
the DESCRIPTION section for such a configuration.
'inaccessible' : Destination can not be reached by
any route known to this signalling point.
'restricted' : Traffic has been restricted from
being sent to the destination. The restricted state
indicates that the primary route for the destination
is unavailable or that it is impacted by some network
event or failure of resource.ro Enumeration .1.3.6.1.4.1.9.9.334.1.2.2.1.1 |

dynamic or static.

cgrtRouteTypeWhen summary or cluster routes are specified this field
will provide additional information about the fully
qualified routes within the specified clusters. Since,
summary or cluster routes represent a group of
destinations it is necessary to collect and maintain
status information on routes that are not available.
Additional, route statements are created dynamically
whenever a TFP or TFR is received on a fully qualified
route represented by a defined summary route. There are
three four types of dynamic route as follows.
List of the possible route status values.
'unknown': Undefined type of route.
'static': A fully-qualified route configured by system
administrator.
'cluster': An ANSI cluster route. A DPC and mask
with length of 16 bits configured by system
administrator.
'summary': An DPC and a mask with length 0-10 for ITU and
0-15,17-23 for ANSI. A summary route is configured by
a system administrator.
'xlist': This route is dynamic and is create whenever TFP
or TFR is received for a point-code represented by a
ANSI cluster route.
'shadow': When a TFP or TFR is received for a point-code
represented by a summary or cluster route all route
statements specified for the summary or cluster
destination are copied. These new routes appear
under the specific fully-qualified destination.
The route will be marked as a shadow when a TFP or
TFR has not been received for that particular route.
'management' : When a TFP or TFR is received for a
point-code represented by a summary route all route
statements specified for the summary destination are
copied. The new routes appear under the
fully-qualified destination specified in the TFR or
TFP. The route specified in the TFR or TFP will be
marked as a dynamic to indicate that MTP3 route
management information is available for this route.
'alias': Route statement is created in response
to conversion statements defined to alias point-codes
across networks.ro Enumeration .1.3.6.1.4.1.9.9.334.1.2.3.1.9 |

'deleted' : Route has been removed.
When the cgrtRouteAdminStatus object is set to the

on the cgrtRouteMgmtStatus and linkset availability.
