Dell Command Line Reference Guide for the S4048–ON System


ipv6 neighbor

Configure a static entry in the IPv6 neighbor discovery.

ipv6 neighbor [vrf vrf-name] {ipv6-address} {interface interface} {hardware_address}

To remove a static IPv6 entry from the IPv6 neighbor discovery, use the no ipv6 neighbor [vrf vrf-name] {ipv6-address} {interface interface} command.

vrf vrf-name
(Optional) Enter the keyword vrf followed by the name of the VRF to install IPv6 routes in that VRF.
Enter the IPv6 address of the neighbor in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal fields of zero.
interface interface
Enter the keyword interface then the interface type and slot/port or number information:
  • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] 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-channel then a number.
  • For a Null interface, enter the keyword null then the Null interface number.
  • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
  • For a tunnel interface, enter the keyword tunnel then the tunnel interface number. The range is from 1 to 16383.
Enter a 48-bit hardware MAC address in nn:nn:nn:nn:nn:nn format.

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.
