Users Guide
NOTE: If a neighboring node does not have an IPv6 address assigned, it must be manually pinged to allow the IPv6
device to determine the relationship of the neighboring node.
NOTE: To avoid problems with network discovery, Dell Networking recommends conguring the static route last or
assigning an IPv6 address to the interface and assigning an address to the peer (the forwarding router’s address) less
than 10 seconds apart.
With ARP, each node broadcasts ARP requests on the entire link. This approach causes unnecessary processing by uninterested
nodes. With NDP, each node sends a request only to the intended destination via a multicast address with the unicast address used
as the last 24 bits. Other hosts on the link do not participate in the process, greatly increasing network bandwidth eciency.

IPv6 Neighbor Discovery of MTU Packets
You can set the MTU advertised through the RA packets to incoming routers, without altering the actual MTU setting on the
interface.
The ipv6 nd mtu command sets the value advertised to routers. It does not set the actual MTU rate. For example, if you set
ipv6 nd mtu to 1280, the interface still passes 1500-byte packets, if that is what is set with the mtu command.
Secure Shell (SSH) Over an IPv6 Transport
Dell Networking OS supports both inbound and outbound SSH sessions using IPv6 addressing.
Inbound SSH supports accessing the system through the management interface as well as through a physical Layer 3 interface.
For SSH conguration details, refer to the Security chapter in the Dell Networking OS Command Line Interface Reference Guide.
Conguration Tasks for IPv6
The following are conguration tasks for the IPv6 protocol.
• Adjusting Your CAM-Prole
• Assigning an IPv6 Address to an Interface
