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
ipv6 route [vrf vrf-name] dest-ipv6–prefix mask {next-hop | interface
interface-type [route-preference]} [bfd]
Parameters
● 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.
● bfd — (Optional) Enable BFD on a specific static route.

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.
Use the bfd option to enable Bidirectional Forwarding detection (BFD) on a specific static route.
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
The following is a sample configuration for enabling BFD on a specific IPv6 static route:
OS10(config)# ipv6 route 2111:dddd:0eee::22/128 2001:db86:0fff::2 bfd

ipv6 routing-header-type0 deny
Configures IPv6 routing header Type 0 packet handling in hardware (fast-path) and kernel (slow-path).
Syntax
[no] ipv6 routing-header-type0 deny fast-path [slow-path]
Parameters
● fast-path—Deny IPv6 routing header Type 0 packets in the hardware.
● slow-path—Deny IPv6 routing header Type 0 packets in hardware and kernel.
Defaults IPv6 routing header Type 0 packets in the hardware are denied.
