By configuring an IPv6 Unicast routing command on a router you are allowing the router to communicate with the IPv6 interface. This is needed if you intend to send or receive data over an IPv6 network.
link-local address
Depends on what Capability you ask IPV6 Capable ? VOIP Capable ? Video Capable ?
Cisco 877 is a router with an ADSL interface and four ethernet ports. Simply speaking it is a rather intelligent version of a usual ADSL modem (or ADSL router) most of us have at home. 877 provides features geared towards small business use from dynamic routing to IPv6, tunelling etc. 877 also uses the standard operating software which is same as many other high end Cisco devices. This makes it practical to deploy 877 in an ISP (Internet Service Provider) environment so that a unique platform can be deployed from Core level to the end-users. It also has a wireless version, called 877W, which offers wi-fi capabilities on top of everything a standard 877 does.
IPv6 includes an improved option mechanism over IPv4. IPv6 options are placed in separate extension headers that are located between the IPv6 header and the transport-layer header in a packet. Most IPv6 extension headers are not examined or processed by any router along a packet's delivery path until it arrives at its final destination. This facilitates a major improvement in router performance for packets containing options

There are a number of technologies that can provide IPv6 translation for IPv4 users, most commonly Dual Stack and 6 to 4 tunneling. DUAL STACK involves running both IPv4 and IPv6 on a single router with the router managing the implementation of either protocol as and when necessary. 6 to 4 tunneling encapsulates an IPv6 frame in and IPv4 frame for tansport over an IPv4 network either to its destination address or a network where the IPv4 frame can be discarded.
NAT in the router Implementing ipv6 would be a better option.
what is the commercial use of ipv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
Short answer - yes.You need to be running Service Pack 1 at a minimum.Service Pack 2 has an even more complete IPv6 stack.To enable IPv6 on XP, open a command prompt window and type:C:\> ipv6 /?Did you then see this result?:C:\> ipv6 /?Could not access IPv6 protocol stack - the stack is not installed.To install, please use 'ipv6 install'.If you did get the above result, simply type:C:\> ipv6 installIt will take a few seconds, and then your Windows XP system will be fully IPv6 enabled.
There are many variables at play here but you could try: Open AirPort Utility (in the Utilities folder within the Application folder) Select the router and then the Advanced tab at the top Select the IPv6 tab Set the IPv6 Mode menu option to Tunnel This will give you an IPv6 Firewall tab which should be clicked Click the + button to add a port Enter a description... such as Minecraft Enter the required port details Click Done
