display ip routing-table extensive

Function

The display ip routing-table extensive command displays detailed information about routes with a specified prefix.

Format

display ip routing-table [ [ vpn-instance vpn-instance-name ] | [ topology topology-name ] ] prefix [ mask | masklength ] extensive

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Displays information about the routing table of an IPv4 address family-enabled VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
topology topology-name	Displays routing information about the specified IPv4 topology instance.	The value is a string of 1 to 31 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive) and can contain numbers, hyphens (-), or underlines (_). When double quotation marks are used around the string, spaces are allowed in the string.
prefix	Displays information about routes with a specified IP prefix list.	The value is in dotted decimal notation.
mask	Specifies the mask in dotted decimal notation.	The value is in dotted decimal notation.
masklength	Specifies the mask length. A 32-bit mask is represented by consecutive 1s, and the mask in dotted decimal notation can be replaced by the mask length.	The value is an integer ranging from 0 to 32.
extensive	Extensive verbose information of the routing table.	-

Usage Guidelines

Usage Scenario

To check detailed information about routes with a specified prefix, run the display ip routing-table extensive command. If the routes recurse to tunnels, information about the recursive tunnels will be displayed in the command output.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display detailed information about routes (with a specified prefix) that recurse to SR-MPLS BE tunnels.
