display ip routing-table vpn-instance

Function

The display ip routing-table vpn-instance command displays information about the routing table of an IPv4 VPN instance.

The display ip routing-table topology command displays routing information about the routing table of a specified IPv4 topology instance.

Format

display ip routing-table vpn-instance vpn-instance-name [ table-name { localmt | msr } ] { ip-address [ [ mask ] | [ mask-length ] ] | host-name host-name } [ longer-match ] [ verbose ]

display ip routing-table topology topology-name [ table-name localmt ] [ [ { ip-address [ [ mask ] | [ mask-length ] ] | host-name host-name } [ longer-match ] ] | [ time-range min-age max-age ] ] [ verbose ]

display ip routing-table topology topology-name [ table-name localmt ] protocol protocol-id [ time-range min-age max-age ] [ inactive | verbose ]

display ip routing-table topology topology-name [ table-name localmt ] ip-address { mask | mask-length } ip-address { mask | mask-length } [ verbose ]

Parameters

Parameter	Description	Value
table-name	Specifies a table of a producer.	-
localmt	Displays routing information about the local multi-topology routing table.	-
ip-address	Displays information about a route to a destination IP address specified in the routing table of an IPv4 VPN instance.	The value is in dotted decimal notation.
mask	Specifies the mask in dotted decimal notation.	The value is in dotted decimal notation.
mask-length	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 that ranges from 0 to 32.
longer-match	Displays only the routes that match the specified network or mask.	-
verbose	Displays detailed information about active and inactive routes.	-
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.
msr	Displays information about the routing table of the multicast static routing table.	-
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.
time-range	Displays routes that are generated within a specified period.	-
min-age	Specifies the start generation time.	The value is a string of characters, in the format of XXdXXhXXmXXs.
max-age	Specifies the end generation time.	The value is a string of characters, in the format of XXdXXhXXmXXs.
protocol protocol-id	Displays routing information about the specified protocol.	-
inactive	Displays the summary of inactive routes only.	-
host-name host-name	Specifies the hostname.	The value is a string of 1 to 255 case-sensitive characters, spaces not supported.

Usage Guidelines

Usage Scenario

When the verbose parameter is not specified, information about only one route is displayed in each line. The contents include the destination address, mask length, protocol, priority, route cost, route flag, next hop, and outbound interface. This command displays only the preferred routes.

Precautions

After learning the ARP entry of a peer end, VLANIF interfaces, QinQ interfaces, or QinQ VLAN tag termination sub-interfaces generate a 32-bit ARP Vlink direct route, and the route is displayed in the command output. Regular physical interfaces do not generate a 32-bit ARP Vlink direct route in this case.

Example

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