NOTE: To avoid problems with network discovery, Dell Networking recommends configuring 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 efficiency.

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 configuration details, refer to the Security chapter in the Dell Networking OS Command Line
Interface Reference Guide.
