FTOS(conf)#ipv6 route 44::0 /64 33::1 ?
<1-255> Distance metric for this route
permanent Permanent route
tag Set tag for this route
FTOS(conf)#ipv6 route 55::0 /64 ?
X:X:X:X::X Forwarding router's address
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format followed by the prefix length in
the /x format.
Range: /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 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet
followed by the slot/port information.
• For a loopback interface, enter the keyword
loopback followed by a number
from zero (0) to 16383.
• For the null interface, enter the keyword
null followed by zero (0).
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet
followed by the slot/port information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE followed by
the slot/port information.
• For a VLAN interface, enter the keyword
VLAN followed by the vlan number.
• For a port channel interface, enter the keyword
port-channel followed by the
port channel number.
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.
Range: 1 to 255
tag value (OPTIONAL) Enter the keyword tag followed by a tag value number.
Range: 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.
