Connectivity Guide

Parameters
• reachable-time milliseconds — Enter the reachable time in milliseconds, from 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, from 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 sending ICMPv6 RA messages.
Syntax
ipv6 nd send-ra
Parameters None
Defaults RA messages are disabled.
Command Mode INTERFACE
Usage Information
• Using ICMPv6 RA messages, the Neighbor Discovery Protocol (NDP) 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 version 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
