Reference Guide

You can also manually congure an IPv6 address by assigning:
• A network prex and the 64-bit interface ID in EUI-64 format (ipv6 address eui64 command)
• A link-local address to be used instead of the link-local address that is automatically congured when IPv6 is enabled (ipv6 address
link-local
command)
To remove all IPv6 addresses from an interface, enter the no ipv6 address autoconfig command. You can manually disable and re-
enable IPv6 processing on an interface congured with an IPv6 address (no ipv6 enable and ipv6 enable commands).
To re-enable stateless autoconguration of an IPv6 link-local address on a switch interface, enter the ipv6 address autoconfig
command.
Congure IPv6 address
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2001:dddd:0eee::4/128
Congure network prex
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2001:FF21:1:1::/64 eui64
Congure link-local address
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address FE80::1/124 link-local
Static IPv6 routing
Congure a static route on an interface to dene an explicit route between two IPv6 networking devices. Static routing is useful for smaller
networks with only one path to an outside network, or to provide security for certain trac types in a larger network.
• Enter the static routing information including the IPv6 address and mask in x:x:x:x::x format in CONFIGURATION mode—prex length
0 to 64.
ipv6 route ipv6–prefix/mask {next-hop | interface interface [route-preference]}
• next-hop—Enter the next-hop IP address in dotted decimal format—A.B.C.D.
• interface interface—Enter the interface type then the slot/port or number information.
• route-preference—(Optional) Enter a route-preference range—1 to 255.
After you congure a static IPv6 route, congure the forwarding router’s address on the interface. The IPv6 neighbor interface must have
an IPv6 address congured.

OS10(config)# ipv6 route 2111:dddd:0eee::22/128 2001:db86:0fff::2
OS10(config)# do show ipv6 route static
