Usage Information
Neighbor Discovery Protocol for IPv6 is defined in RFC 2461 as part of the Stateless Address Autoconfiguration
protocol. It replaces the Address Resolution Protocol used with IPv4. It defines mechanisms for solving problems,
such as:
• Router discovery: Hosts can locate routers residing on a link
• Prefix discovery: Hosts can discover address prefixes for the link.
• Parameter discovery
• Address autoconfiguration — configuration of addresses for an interface
• Address resolution — mapping from IP address to link-layer address
• Next-hop determination• Neighbor Unreachability Detection (NUD): Determine that a neighbor is no longer
reachable on the link
• Duplicate Address Detection (DAD): Allow a node to check whether a proposed address is already in use.
• Redirect: The router can inform a node about a better first-hop.
Use the ipv6 neighbor command to manually configure the IPv6 address of a neighbor to be discovered by the
switch.
NOTE:
The parameters vrf, mac-address, interface are not supported in the batch mode.
ipv6 route
Establish a static IPv6 route.
C9000 Series
Syntax
ipv6 route ipv6-address prefix-length {ipv6-address | interface | interface
ipv6-address} [distance] [tag value] [permanent][weight weight-value [vrf vrf-
name]
To remove the IPv6 route, use the no ipv6 route ipv6-address prefix-length {ipv6-address
| interface | interface ipv6-address} [distance] [tag value] [permanent][weight
weight-value [vrf vrf-name] command.
Parameters
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 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 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 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.
