CLI Guide

To remove the IPv6 route, use the no ipv6 route ipv6-address prefix-length {ipv6-address
| interface | interface ipv6-address} [distance] [tag value] [permanent] command.
Parameters
ipv6-address prex-
length
Enter the IPv6 address in the x:x:x:x::x format then the prex length in the /x format. The
range is from /0 to /128.
NOTE: The :: notation species successive hexadecimal elds of zeros.
interface (OPTIONAL) Enter the following keywords and slot/port or number information:
• For a loopback interface, enter the keyword loopback then a number from zero (0)
to 16383.
• For the null interface, enter the keyword null then zero (0).
•
For a port channel interface, enter the keyword port-channel then the port
channel number. The range is from 1 to 128.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port information.
• 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 congure 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.
Congure 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 species successive hexadecimal elds of zeros.
distance (OPTIONAL) Enter a number as the metric distance assigned to the route. The range is
from 1 to 255.
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.
