How to Configure IPv6 Support on the Cisco ASR 901 Router

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 places the
		router in interface configuration mode. farce
	Example:
	Router(config)# Interface vlan 40
Step 4
	ipv6 enable	Configures IPv6 on the VLAN interface. Though both the
	or	commands automatically configure the link local address
	ipv6 address {ipv6-address/prefix-length	(LLA) on the interface, the ipv6 address command
	prefix-name sub-bits/prefix-length}
		additionally configures an ipv6 address on the interface.
	Example:	• ipv6-address—The IPv6 address to be used.
		• prefix-length—The length of the IPv6 prefix. A decimal
	Router(config-if)# ipv6 enable
	or	value that indicates how many of the high-order
	Router(config-if)# ipv6 address 2000::1/64	contiguous bits of the address comprise the prefix (the
		network portion of the address). A slash mark must
		precede the decimal value.
		• prefix-name—A general prefix, which specifies the
		leading bits of the network to be configured on the
		interface.
		• sub-bits—The subprefix bits and host bits of the address
		to be concatenated with the prefixes provided by the
		general prefix specified with the prefix-nameargument.
