ipv6 route Configures a static IPv6 static route. Syntax Parameters ipv6 route ipv6-prefix mask {next-hop | interface interface-type [routepreference]} • ipv6-prefix - Enter the IPv6 address in x:x:x:x::x format • mask - Enter the mask in slash prefix-length format (/x) • 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 (1 to 255). Default Command Mode Usage Information Not configured CONFIGURATION • When the interface fails, the system withdraws the route. The route reinstalls when the interface comes back up. When a recursive resolution is broken, 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 the generation of error messages on an interface for IPv6 packets with unreachable destinations. Syntax Parameters Defaults Command Mode Usage Information ipv6 unreachables None ICMPv6 unreachable messages are not sent. INTERFACE • By default, when no matching entry for an IPv6 route is found in the IPv6 routing table, the packet is dropped and no error message is sent. Use this command to enable sending an IPv6 destination unreachable error message to the source without dropping the packet. • The no version of this command disables the generation of unreachable destination messages. Example OS10(config)# interface ethernet 1/2/3 OS10(conf-if-eth1/2/3)# ipv6 unreachables Supported Releases 10.4.0E(R1) or later Layer 3 347
