Chapter 39 Configuring IPv6 Unicast Routing
Configuring IPv6
To disable IPv4 routing, use the no ip routing global configuration command. To disable IPv6 routing,
use the no ipv6 unicast-routing global configuration command. To remove an IPv4 address from an
interface, use the no ip address ip-address mask interface configuration command. To remove an IPv6
address from an interface, use the no ipv6 address ipv6-prefix/prefix length eui-64 or no ipv6 address
ipv6-address link-local interface configuration command. To remove all manually configured IPv6
addresses from an interface, use the no ipv6 address interface configuration command without
arguments. To disable IPv6 processing on an interface that has not been explicitly configured with an
IPv6 address, use the no ipv6 enable interface configuration command.
This example shows how to enable IPv4 and IPv6 routing on an interface.
Switch(config)# sdm prefer dual-ipv4-and-ipv6 default
Switch(config)# ip routing
Switch(config)# ipv6 unicast-routing
Switch(config)# interface gigabitethernet1/0/11
Switch(config-if)# no switchport
Switch(config-if)# ip address 192.168.99.1 244.244.244.0
Switch(config-if)# ipv6 address 2001:0DB8:c18:1::/64 eui 64
Switch(config-if)# end
Step 4
interface interface-id Enter interface configuration mode, and specify the Layer 3
interface to configure.
Step 5
no switchport Remove the interface from Layer 2 configuration mode (if it is a
physical interface).
Step 6
ip address ip-address mask [secondary] Specify a primary or secondary IPv4 address for the interface.
Step 7
ipv6 address ipv6-prefix/prefix length eui-64
or
ipv6 address ipv6-address link-local
or
ipv6 enable
Specify a global IPv6 address with an interface identifier in the
low-order 64 bits of the IPv6 address. Specify only the network
prefix; the last 64 bits are automatically computed from the
switch MAC address. This enables IPv6 processing on the
interface.
Specify a link-local address on the interface to be used instead
of the link-local address that is automatically configured when
IPv6 is enabled on the interface. This command enables IPv6
processing on the interface.
Automatically configure an IPv6 link-local address on the
interface, and enable the interface for IPv6 processing. The
link-local address can only be used to communicate with nodes
on the same link.
Step 8
end Return to privileged EXEC mode.
Step 9
show interface interface-id
show ip interface interface-id
show ip v6 interface interface-id
Verify your entries.
Step 10
copy running-config startup-config (Optional) Save your entries in the configuration file.
