Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies the name of a VPN instance of an enabled IPv6 address family.	The value must be an existing VPN instance name.
verbose	Displays detailed information about all the routes in the current routing table, including active and inactive routes.	-
brief	Displays brief information about active routes in the current routing table.	-
ipv6-address	Displays the routes with the specified IPv6 destination 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 prefix length of an IPv6 destination address.	The value is an integer that ranges from 0 to 128.
longer-match	Displays the routes with the specified destination address and mask.	-
ipv6-address1	Specifies the start IPv6 address in an IP address range. ipv6-address1 and ipv6-address2 determine an IP address range. Only the routes in the IP address range are displayed.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
ipv6-address2	Specifies the end IPv6 address in an IP address range. ipv6-address1 and ipv6-address2 determine an IP address range. Only the routes in the IP address range are displayed.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
prefix-length2	Specifies the mask length of the start IPv6 address.	The value is an integer that ranges from 0 to 128.
prefix-length2	Specifies the mask length of the end IPv6 address.	The value is an integer that ranges from 0 to 128.
acl acl6-number	Displays the routes that match the ACL6 with the specified ACL number. If the specified ACL6 does not exist, information about all active routes is displayed.	The value is an integer that ranges from 2000 to 2999.
acl acl6-name	Displays the routes that match the ACL6 with the specified ACL name. If the specified ACL6 does not exist, information about all active routes is displayed.	The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter.
ipv6-prefix ipv6-prefix-name	Displays the routes that match the specified IPv6 prefix list. If the specified IPv6 prefix list does not exist, information about all active routes is displayed.	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.

1: Monitoring level

Usage Guidelines

If the verbose keyword is not specified, the command output includes the destination address, prefix length, protocol type, preference, cost, next hop, outbound interface, tunnel ID, flag, and status of a route.

A recursive route is counted as one route regardless of how many outbound interfaces and next hops the route finds.

How to IP route IPv6?

To configure a basic IPv6 static route, perform these steps..

Enter global configuration mode. device# configure terminal..

Designate the route destination as an IPv6 address in hexadecimal with 16-bit values between colons, as specified in RFC 2373, and include the address prefix length preceded by a slash..

Does IPv6 have a routing table?

The IPv6 Routing Table displays the active routes in the system. It includes a combination of connected routes, static routes, and any routes established through the dynamic routing protocols (i.e. RIP and OSPF). This table applies to IPv6 routes; for IPv4 route data, see Viewing Routing Table.

How does routing work with IPv6?

Routing in IPv6 is almost identical to IPv4 routing under CIDR. The only difference is the addresses are 128-bit IPv6 addresses instead of 32-bit IPv4 addresses. With very straightforward extensions, all of IPv4's routing algorithms, such as OSPF, RIP, IDRP, IS-IS, can be used to route IPv6.
