Parameters

Parameter	Description	Value
verbose	Displays detailed information about BGP4+ public network routes.	-
ipv6-address	Specifies the IPv6 address.	It is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
prefix-length	Specifies the length of the prefix.	The value is an integer that ranges from 0 to 128.

accepted-routes	Displays the public network routes that are received from the peer and filtered through a routing policy.	-
time-range start-time end-time	Displays BGP4+ public network routes that flap within the specified time period. For example, the value 0d0h5m0s of start-time indicates five minutes before the current time. The value 0d0h10m0s of end-time indicates 10 minutes before the current time. All BGP4+ public network routes with the Keepalive time in the range of 5 to 10 minutes are displayed.	The formats of start-time and end-time both are xxdxxhxxmxxs. The d indicates days. The value is an integer ranging from 0 to 10000. The h indicates hours. The value is an integer ranging from 0 to 23. The m indicates minutes. The value is an integer ranging from 0 to 59. The s indicates seconds. The value is an integer ranging from 0 to 59. NOTE: If the value of the d is 10000, the values of the h, m, and s can be only 0.

Usage Guidelines

You can specify different parameters to view the specific routing information.

You can run the display bgp ipv6 routing-table time-range start-time end-time command to view BGP4+ routes that flap within the specified time period. For example, if service traffic is abnormal or CPU usage of the device remains high within a certain time period, you can run this command to check whether route flapping occurs within the specified time period. The faulty route can be viewed in the command output, facilitating fault location.

Local AS number	Local AS number.
BGP routing table entry information of 2001:db8:10::/64	The following information is about 2001:db8:10::/64 routing entries.
From	IP address of the router that sends the route. 2001:db8:10::2 is the IP address of the source interface of the peer with which the BGP connection is established, and 2.2.2.2 is the Router ID of the peer.

origin incomplete	Well-known mandatory property. This property defines the origin of a path and records how a route turns to a BGP route. The property has the following three values: IGP: The priority of this value is the highest. The origin property of the routes that are added to the BGP routing table by using the network (BGP) command is IGP. EGP: The priority of this value is second to that of IGP. The origin property of the routes imported from EGP is EGP. Incomplete: The priority of this value is the lowest. The value indicates the origin of a route is unknown. The origin property of the routes that are added to the BGP routing table by using the import-route (BGP) command is Incomplete.
localpref	Local priority.
pref-val	Value preferred by the protocol.
internal	The BGP route is an internal route.
