                      TOS 0 METRIC:   2 (2)      

LS AGE

Indicates the age of the advertisement in seconds. An asterisk (*) displayed beside the age value indicates that the originator is supporting demand circuits and has indicated that the LSA should not be aged.

LS OPTIONS

Indicates the optional OSPF capabilities supported by the router that originated the advertisement. (The value displayed in parentheses is the hexadecimal options value received in the LSA.) These capabilities are denoted by:

LS OPTION	OSPF capability
E	Processes type 5 externals; when this is not set, the area to which the advertisement belongs has been configured as a stub.
T	Can route based on ToS.
MC	RFC 1584 (Multicast Extensions to OSPF) is supported. This value is never set by OMPROUTE but can be received from other routers.
DC	RFC 1793 (Extending OSPF to Support Demand Circuits) is supported.

LS TYPE

Classifies the advertisement and dictates its contents:

LS TYPE	Advertisement
1	Router links advertisement
2	Network link advertisement
3	Summary link advertisement
4	Summary ASBR advertisement
5	AS external link

LS DESTINATION

Identifies what is being described by the advertisement. It depends on the advertisement type. For router links and ASBR summaries, it is the OSPF router ID. For network links, it is the IP address of the network designated router. For summary links and AS external links, it is a network or subnet number.

LS ORIGINATOR

OSPF router ID of the originating router.

LS SEQUENCE NUMBER

Used to distinguish separate instances of the same advertisement. Should be looked at as a signed 32-bit integer. Starts at 0x80000001, and increments by 1 each time the advertisement is updated.

LS CHECKSUM

A checksum of advertisement contents, used to detect data corruption.

LS LENGTH

The size of the advertisement in bytes.

ROUTER TYPE

Indicates the level of function of the advertising router. (The value displayed in parentheses is the hexadecimal router type value received in the LSA).

ROUTER TYPE	Function level
ASBR	The router is an AS boundary router.
ABR	The router is an area border router.
V	The router is an endpoint of an active virtual link that is using the described area as a transit area.

# ROUTER IFCS

The number of router interfaces described in the advertisement.

LINK ID

Indicates what the interface connects to. Depends on interface type. For interfaces to routers (that is, point-to-point links), the Link ID is the neighbor router ID. For interfaces to transit networks, it is the IP address of the network designated router. For interfaces to stub networks, it is the network or subnet number.

LINK DATA

Four bytes of extra information concerning the link; it is either the IP address of the interface (for interfaces to point-to-point networks and transit networks), or the subnet mask (for interfaces to stub networks).

INTERFACE TYPE

One of the following value:

INTERFACE TYPE	Details
1	Point-to-point connection to another router
2	Connection to transit network
3	Connection to stub network
4	Virtual link

NO. OF METRICS

The number of nonzero ToS values for which metrics are provided for this interface. For the z/OS® implementation, this value will always be 0.

TOS 0 METRIC

The cost of the interface.

The LS age, LS options, LS type, LS destination, LS originator, LS sequence no, LS checksum and LS length fields are common to all advertisements. The Router type and # router ifcs are seen only in router links advertisements. Each link in the router advertisement is described by the Link ID, Link Data, and Interface type fields.

The DISPLAY TCPIP,tcpipjobname,OMPROUTE,OSPF,AREASUM command displays the statistics and parameters for all OSPF areas attached to the router. A sample output with an explanation of entries follows:

SEQNO, AGE, and XSUM

It is possible for several instances of an advertisement to be present in the OSPF routing domain at any one time. However, only the most recent instance is kept in the OSPF link state database (and printed by this command). The LS sequence number (Seqno), LS age (Age), and LS checksum (Xsum) fields are compared to see which instance is most recent. The LS age field is expressed in seconds. Its maximum value is 3600. An asterisk (*) displayed beside an age value indicates that the DONOTAGE bit is on.

The DISPLAY TCPIP,tcpipjobname,OMPROUTE,OSPF,DATABASE,AREAID=area-id command displays a description of the contents of a particular OSPF area link state database. AS external advertisements are omitted from the display. A single line is printed for each advertisement. Each advertisement is defined by the following three parameters:

• Its link state type (called Type)
• Its link state ID (called the LS destination)
• The advertising router (called the LS originator)

A sample output with an explanation of entries follows:

Displays the IPv6 OSPF Router ID and its configuration source. Possible sources are:

• OMPROUTE configuration statement (denoted by a prefixed asterisk "*") that has the RouterID parameter specified:
  1. IPV6_OSPF
  2. ROUTERID (if the IPv6 router ID was inherited from the router ID specified for IPv4)
  3. OSPF (if the IPv6 router ID was inherited from the router ID specified for IPv4)
• The name of the IPv4 interface that was used by OMPROUTE to set the router ID. This indicates that you did not specify an IPv6 router ID, so the IPv6 router ID was inherited from the IPv4 router ID, which had been defaulted by OMPROUTE to the IP address assigned to an IPv4 interface.

For more information about assigned and configured router IDs, see Steps for configuring OSPF and RIP (IPv4 and IPv6) in the z/OS Communications Server: IP Configuration Guide.

IMPORT EXTERNAL ROUTES

Indicates the types of external routes that are imported into the IPv6 OSPF domain. Displayed only when AS Boundary Capability is enabled.

ORIG DEFAULT ROUTE

Indicates whether a default route is originated into the IPv6 OSPF domain. Orig Default Route is displayed only when AS Boundary Capability is enabled.

DEFAULT ROUTE COST

Displays the cost and type of the default route (if originated). Default Route Cost is displayed only when AS Boundary Capability is enabled and Orig Default Route is Always.

DEFAULT FORWARD ADDR

Displays the forwarding address specified in the default route (if originated). Default Forwarding Address is displayed only when AS Boundary Capability is enabled and Orig Default Route is Always.

LEARN HIGHER COST DFLT

Indicates whether IPv6 OSPF will learn default routes from inbound packets when their cost is higher than the default route originated by this host. This parameter is displayed only when AS Boundary Capability is enabled and Orig Default Route is Always.

DEMAND CIRCUITS

Indicates whether demand circuit support is available for IPv6 OSPF interfaces.

DR MAX ADJ ATTEMPT

Establishes a threshold value for maximum number of adjacency attempts to a neighboring designated router. It is used for reporting and controlling futile neighbor state loops.

LS ORIGINATOR

The Router ID of the router that originated the advertisement.

LS ID

Uniquely identifies multiple external LSAs originated by the same router.

SEQNO, AGE

It is possible for several instances of an advertisement to be present in the IPv6 OSPF routing domain at any one time. However, only the most recent instance is kept in the IPv6 OSPF link state database (and printed by this command). The LS sequence number (Seqno) and LS age (Age) fields are compared to see which instance is most recent. The LS age field is expressed in seconds. Its maximum value is 3600. An asterisk (*) displayed beside an age value indicates that the DONOTAGE bit is on.

PREFIX

The prefix being described by the LSA.

The DISPLAY TCPIP,tcpipjobname,OMPROUTE,IPV6OSPF,DATABASE,AREAID=area-id command displays the contents of a particular IPv6 OSPF area link state database. AS external advertisements are omitted from the display. A single line is printed for each advertisement. Each advertisement is defined by the following three parameters:

• Its link state type (called Type)
• The advertising router (called the LS originator)
• Its link state ID

LS ORIGINATOR

The Router ID of the router that originated the advertisement.

LS ID

Uniquely identifies multiple LSAs of the same type originated by the same router.

SEQNO, AGE

It is possible for several instances of an advertisement to be present in the IPv6 OSPF routing domain at any one time. However, only the most recent instance is kept in the IPv6 OSPF link state database (and printed by this command). The LS sequence number (Seqno) and LS age (Age) fields are compared to see which instance is most recent. The LS age field is expressed in seconds. Its maximum value is 3600. An asterisk (*) displayed beside an age value indicates that the DONOTAGE bit is on.

LINKS

Number of links described by the LSA.

ROUTER TYPE

Indicates the level of function of the advertising router.

ROUTER TYPE	Description
ASBR	The router is an AS boundary router.
ABR	The router is an area border router.
V	The router is an endpoint of one of more fully adjacent virtual links having the described area as transit area.
W	The router is a wildcard multicast receiver (OMPROUTE will never set the W option on its own Router LSAs).

ROUTERS

The number of routers attached to the link described by the LSA.

PREFIX

The prefix being described by the LSA.

INTERFACE

Associated interface.

REF LS-TYPE,REF-LS ID

Identifies the referenced Router LSA or Network LSA.

At the end of each type of LSA in the display, the total number of advertisements of that type in the area database is printed, along with a checksum total over all of their contents. The checksum total is simply the 32-bit sum (carries discarded) of the individual advertisement LS checksum fields. This information can be used to quickly determine whether two IPv6 OSPF routers have synchronized databases.

The DISPLAY TCPIP,tcpipjobname,OMPROUTE,IPV6OSPF,ROUTERS command displays all routes to other routers that have been calculated by IPv6 OSPF and are now present in the routing table. A sample output with an explanation of entries follows:

DESTINATION

Indicates the IP destination, along with its prefix length.

NEXT HOP

Indicates the IP address of the next router on the path toward the destination. A number in parentheses at the end of the column indicates the number of equal-cost routes to the destination. Use the DISPLAY TCPIP,tcpipjobname,OMPROUTE,RT6TABLE,DEST=ip_addr command to obtain a list of the next hops.

TYPE

Indicates how the route was derived:

DFLT

Indicates a route defined using the IPV6_DEFAULT_ROUTE configuration statement in the OMPROUTE configuration file.

DIR

Indicates a directly connected prefix or host.

RIP

Indicates a route that was learned through the IPv6 RIP protocol.

DEL

Indicates the route has been deleted.

Restriction: Deleted routes are shown only when RIP is active and only as long as RIP needs to advertise to neighboring routers that they have been deleted.

STAT

Indicates a nonreplaceable statically configured route.

SPF

Indicates that the route is an IPv6 OSPF intra-area route.

SPIA

Indicates that the route is an IPv6 OSPF interarea route.

SPE1

Indicates IPv6 OSPF external routes (type 1).

SPE2

Indicates IPv6 OSPF external routes (type 2).

RANGE

Indicates a route type that is an active IPv6 OSPF area address range and is not used in forwarding packets.

RSTA

Indicates a static route that is defined as replaceable.

RADV

Indicates a route that was learned by the TCP/IP stack through the IPv6 Router Discovery protocol.

An asterisk (*) after the route type indicates that the route has a directly connected backup. A percent sign (%) after the route type indicates that IPv6 RIP updates are always accepted for this destination.

COST

Indicates the route cost.

Table 3. OMPROUTE IPv6 Route Type and COST Value mapping

Route Type	COST Value
SPF or SPIA	The OSPF cost of the route.
SPE1	The OSPF cost to get to the AS boundary router or forwarding address that is used to reach the destination, plus the external cost.
SPE2	The external cost.
RIP	The RIP metric
STAT or RSTA	0 when the route is direct. 1 when the route is indirect.
DIR or SBNT	1
RNGE	The OSPF cost of the range.
DFLT	0
RADV	1 when the router advertisement indicated a preference of high. 2 when the router advertisement indicated a preference of medium. 3 when the router advertisement indicated a preference of low.

AGE

Indicates the time that has elapsed since the routing table entry was last refreshed. For routes that have the route type DEL or RIP, this value increments by a factor of 10 for each 10–second increase in age. If the TCP/IP stack enters a storage shortage condition, all routes that have the route type DEL or RIP are refreshed when the shortage condition is relieved.

NETS DELETED

Indicates the number of routes that have been deleted from the OMPROUTE routing table and not replaced. Use the DTCPIP,,OMPROUTE,RT6TABLE,DELETED command to list these routes.

NETS INACTIVE

Used for internal debugging purposes only.

The DISPLAY TCPIP,tcpipjobname,OMPROUTE,RT6TABLE,DELETED command displays the routes that have been deleted from the OMPROUTE IPv6 routing table and that have not been replaced or recycled through garbage collection (garbage collection occurs only when IPv6 RIP is running). A sample output follows. The explanation for the entries is the same as for the Display TCPIP,tcpipjobname,OMPROUTE,RT6TABLE command (see OMPROUTE IPv6 main routing table).
