display ipv6 routing-table time-range

Function

The display ipv6 routing-table time-range command displays information about routes generated in a specified time range in an IPv6 routing table.

Format

display ipv6 routing-table [ vpn-instance vpn-instance-name ] time-range min-age max-age [ verbose | brief ]

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Displays information about routes generated in a specified time range in the IPv6 routing table of the specified VPN instance. If this parameter is not specified, the display ipv6 routing-table time-range command displays information about routes generated in a specified time range in the public IPv6 routing table.	The value must be an existing VPN instance name.
min-age	Specifies the end time of the period when routes are generated.	The value is in xxdxxhxxmxxs format. d indicates days. The value is an integer that ranges from 0 to 10000. h indicates hours. The value is an integer that ranges from 0 to 23. m indicates minutes. The value is an integer that ranges from 0 to 59. s indicates seconds. The value is an integer that ranges from 0 to 59. For example, enter 5d4h30m20s to specify 5 days, 4 hours, 30 minutes, and 20 seconds. NOTE: If the value of d is 10000, the values of h, m, and s can only be 0.
max-age	Specifies the start time of the period when routes are generated.	The value is in xxdxxhxxmxxs format. d indicates days. The value is an integer that ranges from 0 to 10000. h indicates hours. The value is an integer that ranges from 0 to 23. m indicates minutes. The value is an integer that ranges from 0 to 59. s indicates seconds. The value is an integer that ranges from 0 to 59. For example, enter 5d4h30m20s to specify 5 days, 4 hours, 30 minutes, and 20 seconds. NOTE: If the value of d is 10000, the values of h, m, and s can only be 0.
verbose	Displays detailed information about active and inactive routes. If this parameter is not specified, the display ipv6 routing-table time-range command displays only brief information about active routes.	-
brief	Displays brief information about active and inactive routes.	-

Usage Guidelines

Usage Scenario

If route flapping occurs on a network, to find the flapping route rapidly and accelerate fault location, run the display ipv6 routing-table time-range command and specify a small time range.

Precautions

max-age must be larger than min-age. Otherwise, the display ipv6 routing-table time-range command does not display any information.

If max-age is larger than min-age but no route is generated within this time range, the display ipv6 routing-table time-range command displays only the table heading.

Example

# Display information about public network IPv6 routes generated in the last 2 hours, 20 minutes, and 10 seconds.
