display ipv6 routing-table vpn-instance

Function

The display ipv6 routing-table vpn-instance command displays the routing table of an IPv6 address family-enabled VPN instance.

Format

display ipv6 routing-table vpn-instance vpn-instance-name { ipv6-address [ prefix-length ] | host-name host-name } [ longer-match ] [ verbose ]

Parameters

Parameter	Description	Value
ipv6-address	Specifies the destination IPv6 address.	The value 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 IPv6 address prefix.	The value is an integer ranging from 0 to 128.
host-name host-name	Specifies the hostname.	The value is a string of 1 to 255 case-sensitive characters, spaces not supported.
longer-match	Displays only the VPN IPv6 routes that match the specified network and mask.	-
verbose	Displays detailed information about active and inactive routes.	-
vpn-instance vpn-instance-name	Displays information about the routing table of an IPv6 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.

Usage Guidelines

Usage Scenario

To check the routing table of the IPv6 address family-enabled VPN instance, run the display ipv6 routing-table vpn-instance command. The command output includes the destination address, prefix length, protocol type, priority, cost, next hop, and outbound interface.

a recursive route is counted as one route no matter how many outbound interfaces and next hops the route finds.

This command without verbose specified displays preferred routes only.

Example

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

# Display information about routes that recurse to SRv6 BE tunnels and information about the actual outbound interfaces by using the value of the RelayNextHop field in the display ip routing-table vpn-instance vpn-instance-name verbose command output as the destination address.
