ipv6-address} [distance] [tag value] [permanent] [weight]
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

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 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-

• For a Null interface, enter the keyword null then the Null

ipv6-address (OPTIONAL) Enter the forwarding router IPv6 address in the
x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal
