Figure 25-3. NDP Router Redirect
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
ipv6 nd mtu is set to 1280, the interface will still pass 1500-byte
packets, if that is what is set with the
mtu command.
SSH over an IPv6 Transport
IPv6 SSH is supported on the S5000 platform.
FTOS 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.
Refer to the
Security Commands chapter in the FTOS Command Line Interface Reference document for SSH
configuration details.
