OSPFv3 Debug Commands on Cisco IOS XR


This chapter describes the commands used to configure and monitor the IPv6 Open Shortest Path First Version 3 (OSPFv3) routing protocol on Cisco IOS XR software.

debug ospfv3 acl

To display debugging information for the Open Shortest Path First Version 3 (OSPFv3) access lists, use the debug ospfv3 acl command in EXEC mode. To disable debugging output, use the no form of this command.

debug ospfv3 instance-name acl

no debug ospfv3 instance-name acl

Syntax Description

instance-name

Name that uniquely identifies an OSPF routing process. The instance-name argument is defined by the router ospf command.


Defaults

Debugging is disabled.

Command Modes

EXEC

Command History

Release
Modification

Release 2.0

This command was introduced on the Cisco CRS-1.

Release 3.0

No modification.

Release 3.2

This command was supported on the Cisco XR 12000 Series Router.

Release 3.3.0

No modification.


Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Debugging output is assigned high priority in the CPU process and, therefore, can affect system performance. For more information about the impact on system performance when using debug commands, refer to Using Debug Commands on Cisco IOS XR Software.


Caution The debug ospfv3 acl command generates a substantial amount of output. Use the command only when traffic on the IP network is low so that other activity on the system is not adversely affected.

Command
Description

undebug

Enters debug mode to disable or reset multiple active debug command sessions.


debug ospfv3 adj

To display information about OSPFv3 adjacency events for an interface or all interfaces, use the debug ospfv3 adj command in EXEC mode. To disable debugging output, use the no form of this command.

debug ospfv3 instance-name adj [interface-type interface-instance]

no debug ospfv3 instance-name adj [interface-type interface-instance]

Syntax Description

instance-name

Name that uniquely identifies an OSPFv3 routing process. The instance name is any alphanumeric string no longer than 40 characters. The instance-name argument is defined by the router ospfv3 command.

interface-type

(Optional) Interface type. For more information, use the question mark (?) online help function.

interface-instance

(Optional) Either a physical interface instance or a virtual interface instance as follows:

Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation.

rack: Chassis number of the rack.

slot: Physical slot number of the modular services card or line card.

module: Module number. A physical layer interface module (PLIM) is always 0.

port: Physical port number of the interface.

Note In references to a Management Ethernet interface located on a route processor card, the physical slot number is alphanumeric (RP0 or RP1) and the module is CPU0.
Example: interface MgmtEth0/RP1/CPU0/0.

Virtual interface instance. Number range varies depending on interface type.

For more information about the syntax for the router, use the question mark (?) online help function.


Defaults

Debugging is disabled.

debug ospfv3 packet

To display information about each OSPFv3 packet sent or received, use the debug ospfv3 packet command in EXEC mode. To disable debugging output, use the no form of this command.

debug ospfv3 instance-name packet [interface-type interface-instance]

no debug ospfv3 instance-name packet [interface-type interface-instance]

Syntax Description

instance-name

Name that uniquely identifies an OSPFv3 routing process. The instance name is any alphanumeric string no longer than 40 characters. The instance name is defined by the router ospfv3 command.

interface-type

(Optional) Interface type. For more information, use the question mark (?) online help function.

interface-number

(Optional) Either a physical interface instance or a virtual interface instance as follows:

Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation.

rack: Chassis number of the rack.

slot: Physical slot number of the modular services card or line card.

module: Module number. A physical layer interface module (PLIM) is always 0.

port: Physical port number of the interface.

Note In references to a Management Ethernet interface located on a route processor card, the physical slot number is alphanumeric (RP0 or RP1) and the module is CPU0.
Example: interface MgmtEth0/RP1/CPU0/0.

Virtual interface instance. Number range varies depending on interface type.

For more information about the syntax for the router, use the question mark (?) online help function.

This command was supported on the Cisco XR 12000 Series Router.

Release 3.3.0

No modification.


Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Debugging output is assigned high priority in the CPU process and, therefore, can affect system performance. For more information about the impact on system performance when using debug commands, refer to Using Debug Commands on Cisco IOS XR Software.

Use the debug ospfv3 rtrid command to obtain information about how the OSPFv3 routing process selects the router ID (32-bit IP address) that is used to uniquely identify the router.

The router ID can be configured by using the router-id command. If the router-id command is not configured, the router ID is the highest IP address for an interface on the router, with any loopback interface taking precedence.

Command
Description

router-id

Configures a router ID for the OSPFv3 routing process.

undebug

Enters debug mode to disable or reset multiple active debug command sessions.


debug ospfv3 spf

To display information about the shortest path first (SPF) calculation that the OSPFv3 routing process uses to generate routes, use the debug ospfv3 spf command in EXEC mode. To disable debugging output, use the no form of this command.

debug ospfv3 instance-name spf {external | inter | intra | schedule | statistics | topology}

no debug ospfv3 instance-name spf {external | inter | intra | schedule | statistics | topology}

Syntax Description

instance-name

Name that uniquely identifies an OSPFv3 routing process. The instance name is any alphanumeric string no longer than 40 characters. The instance name is defined by the router ospfv3 command.

external

Displays information only about the OSPFv3 SPF external route.

inter

Displays information only about the OSPFv3 SPF inter-route.

intra

Displays information only about the OSPFv3 SPF intra-route.

schedule

Displays information only about when OSPFv3 SPF is scheduled to run.

statistics

Displays information about performance data for the OSPFv3 SPF computations.

topology

Displays information only about the OSPFv3 SPF topology changes.

Use the debug opsfv3 spf command to obtain information about the SPF calculation that OSPFv3 uses to generate routes from its link-state database. Information can be specified for different SPF areas, such as the external routes of the autonomous system and the internal topology route table.
