Parameters

Parameter	Description	Value
vpn-instance-name	Specifies the name of a VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
verbose	Displays detailed information about active and inactive routes in the routing table of the current VPN instance.	-
brief	Displays brief information about active routes in the routing table of the current VPN instance.	-
acl	Uses ACL6 to filter the command output. If the specified ACL6 does not exist, information about all active routes is displayed.	-
acl6-number	Specifies the number of a basic ACL6.	-
longer-match	Displays only the VPN routes that match the specified network and mask.	-
ipv6-address	Specifies the destination IPv6 address.	-
prefix-length	Specifies the length of the IPv6 address prefix.	-
ipv6-address1 / ipv6-address2	Specifies the IPv6 address. ipv6-address1 and ipv6-address2 together determine an address range. Only the VPN routes in the address range are displayed.	-
prefix-length1 / prefix-length2	Specifies the length of the IPv6 address prefix.	-
ipv6-prefix ipv6-prefix-name	Specifies the name of the IPv6 prefix list.	The name is a string of 1 to 169 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
statistics	Displays integrated route statistics in the routing table of the VPN instance.	-
direct	Displays direct IPv6 routes.	-
static	Displays IPv6 static routes.	-
bgp	Displays BGP4+ routes.	-
isis	Displays IS-IS IPv6 routes.	-

ripng	Displays RIPng routes.	-
unr	Displays user network routes.	-
inactive	Displays the summary of inactive routes only.	-

Usage Guidelines

Usage Scenario

The command output includes the destination address, prefix length, protocol type, preference, cost, next hop, and outbound interface.

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

This command without the parameter verbose displays the currently preferred routes only.

When using the display ipv6 routing-table vpn-instance vpn-instance-name ipv6-address prefix-length [ longer-match ] [ verbose ] command, you can select parameters in the command as required.

If ipv6-address prefix-length is specified, the VPN routes that accurately match the destination address are displayed.
If ipv6-address prefix-length longer-match is specified, the IPv6 routes with the destination address within the specified address range are displayed. If the prefix length is 0, all routes in the routing table of the VPN instance are displayed.

For example, there are four routes in the routing table of the VPN instance named vpna, 2000::20/128, 2000::/100, 2000::/64, and 1000::/64.

If the display ipv6 routing-table vpn-instance vpna 2000:: 64 command is used, only 2000::/64 is displayed.
If the display ipv6 routing-table vpn-instance vpna 2000:: command is used, only 2000::/100 is displayed.
If the display ipv6 routing-table vpn-instance vpna 2000:: 127 longer-match command is used, only 2000::/100 and 2000::/64 are displayed.
If the display ipv6 routing-table vpn-instance vpna 2000:: 0 longer-match command is used, four routes are displayed.

Precautions

If the specified ip-prefix ip-prefix-name does not exist, the command displays all of the currently preferred routes.
