Usage
Information
By default, all prefixes configured as addresses on the interface are advertised. This
command allows control over the individual parameters per prefix; the
default keyword can
be used to use the default parameters for all prefixes. If a prefix has been configured with
lifetime parameter values, the default values cannot be applied using the
ipv6 nd prefix default
no-autoconfig
command.
ipv6 route
c e s
Establish a static IPv6 route.
Syntax
ipv6 route ipv6-address prefix-length {ipv6-address | interface | interface ipv6-address}
[
distance] [tag value] [permanent]
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
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
