debugging rm ipv6

Function

The debugging rm ipv6 command enables route management debugging. After the function is enabled, debugging information about route management is output on a screen.

The undo debugging rm ipv6 command disables route management debugging.

By default, the debugging of route management is disabled.

Format

debugging rm ipv6 { { all | download | producer | importer | subscriber } [ ipv6-prefix ip-prefix-name ] | event }

undo debugging rm ipv6 { all | event | download | producer | importer | subscriber }

Parameters

Parameter	Description	Value
all	Enables all debugging functions.	-
download	Enables information debugging for the route delivery process.	-
producer	Enables information debugging for producer-related processes.	-
importer	Enables information debugging for importer-related processes.	-
subscriber	Enables information debugging for subscriber-related processes.	-
ipv6-prefix ip-prefix-name	Outputs only the debugging information corresponding to an IPv6 address prefix.	The value is a string of 1 to 169 case-sensitive characters, spaces not supported.
event	Enables information debugging for event handling processes defined in the route management module.	-
ipv6	Enables IPv6 route debugging of the route management module.	-

Usage Guidelines

Usage Scenario

To check an internal route management process, you can enable debugging for the process, so that information about the process is output to a screen.

Different debugging functions are designed for different processes. The following debugging options are available:

subscriber: If you select this option, debugging information about subscriber-related processes is displayed. This option can be selected to output relevant information for analysis when a route subscriber cannot subscribe to routes.
importer: If you select this option, debugging information about importer-related processes is displayed. This option can be selected to output relevant information for analysis when a route importer cannot import routes.
download: If you select this option, debugging information about the route delivery process is displayed. This option can be selected to output relevant information for analysis when routes forwarded by the bottom layer are inconsistent with routes in route management.
event: If you select this option, debugging information about event handling processes defined in the route management module is displayed. This option can be used with other options, so that event debugging is also enabled after debugging functions are enabled.
producer: If you select this option, debugging information about producer-related processes is displayed. This option can be selected to output relevant information for analysis when the routing protocol exists but the route management module does not contain information about a route.
all: If you select this option, debugging information about all processes is displayed. This option can be selected to output relevant information for analysis when you are not sure which option to select or the cause of a fault is not clear.

Prerequisites

Global terminal debugging must be simultaneously enabled for relevant debugging information to be output on the screen.
