Link-local IPv6 addressing
Before you congure an interface for IPv6 addressing, determine how the interface is intended to be used. Decide if you would like to use
automatic IPv6 local-link interface addressing or per-interface link-local addressing. The no version of this command removes all manually
congured IPv6 addresses.
1 (Optional) Enter the IPv6 address in x:x:x:x::x format, then the prex length in /x format (/0 to /128) in INTERFACE mode to manually
congure the link-local address.
ipv6 address ipv6-address/mask link-local
2 (Optional) Enable IPv6 addressing to automatically congure the link-local address in INTERFACE mode.

Enable IPv6 link-local addressing
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2001:0db8:2345::/48 link-local
OS10(conf-if-eth1/1/8)# do commit
Enable automatic IPv6 addressing
OS10(config)# interface ethernet 1/1/7
OS10(conf-if-eth1/1/7)# ipv6 enable
OS10(conf-if-eth1/1/7)# do commit
Remove all IPv6 addressing on interface
OS10(conf-if-eth1/1/9)# no ipv6 address
Enable static IPv6 routing
Determine if you would like to use static IPv6 routing. Static routes are manually congured and dene an explicit route between two
networking devices. Static routing is useful for smaller networks with only one path to an outside network, or to provide security for certain
type of trac in a larger network.
Once you congure a static IPv6 route and congure the forwarding router’s address on a neighbor interface, the IPv6 neighbor does not
show in the show ipv6 route command output.
1 Enter the static routing information including the IPv6 address and mask in x:x:x:x::x format in CONFIGURATION mode—prex 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.
