SUMMARY STEPS

1.enable

2.configure terminal

3.interface type number

4.ipv6 address ipv6-address/prefix-length{eui-64 link-local anycast}

5.ipv6 enable

6.exit

7.ipv6 unicast-routing

8.ipv6 cef

DETAILED STEPS

	Command or Action	Purpose
Step 1
	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	interface type number	Specifies an interface type and number and enters interface
		configuration mode.
	Example:
	Router(config)# interface vlan 40
Step 4
	ipv6 address ipv6-address/prefix-length {eui-64	Configures an IPv6 address based on an IPv6 general prefix
	link-local anycast}	and enables IPv6 processing on an interface.
	Example:	• eui-64—Specifies the global IPv6 addresses with an
		interface identifier (ID) in the low-order 64 bits of the
	Router(config-if)# ipv6 address	IPv6 address. Only the 64-bit network prefix for the
	2001:DB8:FFFF::2/64	address needs to be specified; the last 64 bits are
		automatically computed from the interface ID.
		• link-local—Specifies the link-local address on the
		interface that is used instead of the link-local address
		that is automatically configured when IPv6 is enabled
		on the interface.
		• anycast—Specifies an IPv6 anycast address.
Step 5
	ipv6 enable	Enables IPv6 on the interface.
	Example:
	Router(config-if)# ipv6 enable
