ipv6 route
Establish a static IPv6 route.
Syntax
ipv6 route [vrf vrf-name] ipv6-address prefix-length {ipv6-address |
interface | interface ipv6-address} [distance] [name description] [tag
value] [permanent] [weight weight-value]
To remove the IPv6 route, use the no ipv6 route command.
Parameters
vrf vrf-name (Optional) Enter the keyword vrf followed by the name of the VRF to install IPv6
routes in that VRF.
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format then the prefix length in the /x
format. The range is from /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
interface (OPTIONAL) Enter the following keywords and slot/port or number information:
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port[/subport] information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
● For a Loopback interface, enter the keyword loopback then a number from 0
to 16383.
● For a port channel interface, enter the keywords port-channel then a
number.
● For a Null interface, enter the keyword null then the Null interface number.
●
For a tunnel interface, enter the keyword tunnel then the tunnel interface
number. The range is from 1 to 16383.
● For a VLAN interface, enter the keyword VLAN then the vlan number. The
range is from 1 to 4094.
If you configure a static IPv6 route using an egress interface and enter the ping
command to reach the destination IPv6 address, the ping operation may not work.
Configure the IPv6 route using a next-hop IPv6 address in order for the ping
command to detect the destination address.
ipv6-address (OPTIONAL) Enter the forwarding router IPv6 address in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
distance (OPTIONAL) Enter a number as the metric distance assigned to the route. The
range is from 1 to 255.
name description (OPTIONAL) Enter the keyword name and the description for the IPv6 static route
configuration.
tag value (OPTIONAL) Enter the keyword tag then a tag value number. The range is from 1
to 4294967295.
permanent (OPTIONAL) Enter the keyword permanent to specify that the route is not to be
removed, even if the interface assigned to that route goes down.
NOTE: If you disable the interface with an IPv6 address associated with the
keyword permanent, the route disappears from the routing table.
weight weight-
value
Enter the keyword weight followed by a weight value. The range is from 0 to 255.
NOTE: Weight for a static route can be added only for the destination address
and not for the route pointing to destination a interface.
