Reference Guide

Parameters
• reachable-time milliseconds — Enter the reachable time in milliseconds (0 to 3600000).
Defaults 0
Command Mode INTERFACE
Usage Information The no version of this command restores the default reachable time. 0 indicates that no reachable time is sent in
RA messages.
Example
OS10(config)# interface ethernet 1/2/3
OS10(conf-if-eth1/2/3)# ipv6 nd reachable-time 1000
Supported Releases 10.4.0E(R1) or later
ipv6 nd retrans-timer
Sets the time between retransmitting neighbor solicitation messages.
Syntax
ipv6 nd retrans-timer seconds
Parameters
• retrans-timer seconds — Enter the retransmission time interval in milliseconds (100 to 4292967295).
Defaults Not congured
Command Mode INTERFACE
Usage Information The no version of this command disables the congured retransmission timer.
Example
OS10(config)# interface ethernet 1/2/3
OS10(conf-if-eth1/2/3)# ipv6 nd retrans-timer 1000
Supported Releases 10.4.0E(R1) or later
ipv6 nd send-ra
Enables the sending of ICMPv6 Router Advertisement messages.
Syntax
ipv6 nd send-ra
Parameters None
Defaults RA messages are disabled.
Command Mode INTERFACE
Usage Information
• Using ICMPv6 Router Advertisement messages, the Neighbor Discovery protocol advertises the IPv6
addresses of IPv6-enabled interfaces and learns of any address changes in IPv6 neighbors. Before you enable
sending RA messages, the switch must be in Router mode with IPv6 forwarding enabled and stateless
autoconguration disabled (no ipv6 address autoconfig command).
• The no ipvd nd send-ra command disables RA messages.
Example
OS10(config)# interface ethernet 1/2/3
OS10(conf-if-eth1/2/3)# ipv6 nd send-ra
Supported Releases 10.4.0E(R1) or later
