If no IPv4 addresses are present, the router ID selection process will fail. configure iBGP between routers A and B, AS 65000, that will exchange IPv4 and IPv6

Following is the list of top 5 wireless routers that are IPv6-ready. These are not the only routers on the market that support IPv6; many others do and even more will also support it via a Under these conditions, routers can forward the IPv6 traffic in hardware despite the EHs. Access Lists (ACL) applied on router interfaces however, can change the router's IPv6 forwarding performance characteristics when extension headers are present. Nov 28, 2016 · Router's IPv6 Address on WAN. This field shows the IPv6 address that is acquired for the router's WAN (or Internet) interface. The number after the slash (/) is the length of the prefix, which is also indicated by the underline (_) under the IPv6 address. If no address is acquired, the field displays Not Available. IPSec support is required in a full IPv6 implementation. No identification of payload for QoS handling by routers is present within the IPv4 header. Payload identification for QoS handling by routers is included in the IPv6 header using the Flow Label field. For more information, see Option to provide QoS classification data. In a typical IPv6 packet, no extension headers are present. If special handling is required by either the intermediate routers or the destination, one or more extension headers are added by the sending host. Each extension header must fall on a 64-bit (8-byte) boundary. Note: Please make sure that you are provided IPv6 internet service by your internet provider, Comcast. If not, please contact with your IPv6 internet provider first. Physical Connection. 1. Power on­ your modem. 2. Connect the Internet port on your Router to the Modem’s LAN port with an Ethernet cable.

Since there is no NAT in IPv6, im assuming that the ULA will be used for all internal communications between internal subnets and GUA address is used for anything that needs to go external? From a routing table perspective, if you are using GUA's internally, will the routing table in the router just be filled with GUA addresses?

IPv6 uses 128-bit addresses, instead of the meagre 32-bit IPv4 addresses, precisely so that crude workarounds like NAT need not be used. You can use NAT with IPv6, but it makes little sense - if you can live with NAT, why would you switch to IPv6 at all ? However, without NAT, then no "firewall effect", flimsy as it could be. Which IPv6 address type identifies the routers within a given address scope and sends traffic to the nearest router, as determined by the local routing protocols? Anycast address In general terms, there are three ways a computer receives an IPv4 or IPv6 address. The Internet routers (named “boxes”) are property of ISP and the only option I have is an "enable IPv6" checkbox on the customer page, I don't have any access to router configuration itself and no one other option than enabling or disabling ipv6. The routers between LAN and NML (named “routers”) are standard Debian systems running on Nov 28, 2016 · If your ISP did not provide details, select IPv6 Tunnel. If you are not sure, select Auto Detect so that the router detects the IPv6 type that is in use. If your Internet connection does not use PPPoE, DHCP, or fixed, but is IPv6, select Auto Config .

The next phase of autoconfiguration involves obtaining a router advertisement or determining that no routers are present. If routers are present, the routers send router advertisements that specify what type of autoconfiguration a host should perform. Routers send router advertisements periodically.

Address Description; IPv4 compatible address: used by dual-stack nodes that are communicating with IPv6 over an IPv4 infrastructure. When the IPv4-compatible address is used as an IPv6 destination, IPv6 traffic is automatically encapsulated with an IPv4 header and sent to the destination by using the IPv4 infrastructure. Value 59 (No Next Header) in the Next Header field indicates that there is no next header whatsoever following this one, not even a header of an upper-layer protocol. It means that, from the header's point of view, the IPv6 packet ends right after it: the payload should be empty. Since there is no NAT in IPv6, im assuming that the ULA will be used for all internal communications between internal subnets and GUA address is used for anything that needs to go external? From a routing table perspective, if you are using GUA's internally, will the routing table in the router just be filled with GUA addresses? So when we turn on IPv6 on a worldwide basis on June 8 as a 24-hour test (World IPv6 Day), I'm sure there will be things that don't work and those need to be addressed (no pun intended).
