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 IPv6enabled 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 autoconfiguration 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 ipv6 route Configures a static IPv6 static route. Syntax Parameters ipv6 route [vrf vrf-name] dest-ipv6-prefix mask {next-hop | interface interface-type [route-preference]} • vrf vrf-name - (Optional) Enter vrf then the name of the VRF to install IPv6 routes in that VRF. • dest-ipv6-prefix - Enter the destination IPv6 address in x:x:x:x::x format. • mask - Enter the mask in slash prefix-length /x format. • next-hop - Enter the next-hop IPv6 address in x:x:x:x::x format. • interface interface-type - Enter the interface type then the slot/port or number information. The interface types supported are: Ethernet, port-channel, VLAN, and Null. • route-preference - (Optional) Enter a route-preference range, from 1 to 255. Default Not configured Command Mode CONFIGURATION Usage Information When the interface fails, the system withdraws the route. The route reinstalls when the interface comes back up. When a recursive resolution breaks, the system withdraws the route. The route reinstalls when the recursive resolution is satisfied. After you create an IPv6 static route interface, if you do not assign an IP address to a peer interface, you must manually ping the peer to resolve the neighbor information. The no version of this command deletes the IPv6 route configuration. Example OS10(config)# ipv6 route 2111:dddd:0eee::22/128 2001:db86:0fff::2 OS10(config)# ipv6 route 2111:dddd:0eee::22/128 interface null 0 Supported Releases 10.2.0E or later ipv6 unreachables Enables generating error messages on an interface for IPv6 packets with unreachable destinations. Syntax Parameters ipv6 unreachables None Layer 3 657
