IPV6 STATIC ROUTING -learn Internet protocol version 6 Static routing in Hindi and Urdu
When the traffic traverse from one network to another, the network layer device, e.g., router needs to know about the destination network. It does not matter for the router how it gets the information about that destination, but it should be in the routing table of that router.

We can provide the information about the route to the router, either statically or dynamically. The routing process is almost similar in the IPv4 and IPv6. The routing protocols in IPv6 like RIPng (RIP New Generation), OSPFv3, EIGRP for IPv6, IS-IS for IPv6, MP-BGP4 (Multiprotocol BGP-4) have been redefined with the advance features of the IPv6.
In the small network, we can configure the routes statically on every router. But in the big network or networks, we use dynamic routing protocols which provide the information about the route to the router dynamically.
Enable IPv6 on the Router
When we apply IPv6 address on the interface of a router, that router becomes the member of the FF02::1 (All-IPv6 devices) and this router will be a IPv6 device only and will not be capable of forwarding the ICMPv6 Router Advertisement messages and routing protocols packets.
As more IPv6 deployments continue to emerge, Cisco has steadily added more and more
IPv6 content to its certification exams. CCNA now includes basic IPv6 concepts and configuration,
with this version of the CCNP ROUTE exam examining IPv6 to greater depth
than its predecessor BSCI exam.
In particular, ROUTE includes the basic concepts, configuration,
and verification of most of the router-based tools needed to deploy IPv6 in the
Enterprise. As with most of the other topics, ROUTE’s coverage of IPv6 does not include
all skills and knowledge to plan an Enterprise IPv6 deployment, but it does include
enough to take an IPv6 design plan and make a good start on developing an IPv6 implementation
and verification plan.
For example, consider the following IPv6 address that is assigned to a host on a LAN:
2000:1234:5678:9ABC:1234:5678:9ABC:1111/64
This value represents the full 128-bit IP address–there are no opportunities to even abbreviate
this address. However, the /64 means that the prefix (subnet) in which this address resides
is the subnet that includes all addresses that begin with the same first 64 bits as the
address.
Next, one last fact about the rules for writing prefixes before seeing some examples and
moving on. If the prefix length is not a multiple of 16, then the boundary between the prefix
and the interface ID (host) part of the address is inside a quartet. In such cases, the prefix
value should list all the values in the last octet in the prefix part of the value. For
example, if the address just shown with a /64 prefix length instead had a /56 prefix length,
the prefix would include all of the first 3 quartets (a total of 48 bits), plus the first 8 bits of
the fourth quartet. The next 8 bits (last 2 hex digits) of the fourth octet should now be binary
0s, as part of the host portion of the address.
Stateful DHCP for IPv6
IPv6 hosts can use stateful DHCP to learn and lease an IP address and corresponding prefix
length (mask), the IP address of the default router, and the DNS IP address(es). The
concept works basically like DHCP for IPv4; the host sends a (multicast) packet searching
for the DHCP server.
When a server replies, the DHCP client sends a message asking for a
lease of an IP address, and the server replies, listing an IPv6 address, prefix length, and
DNS IP addresses. (Note that Stateful DHCPv6 does not supply the default router information,
instead relying on Neighbor Discovery Protocol between the client and local
routers.)
The names and formats of the actual DHCP messages have changed quite a bit
from IPv4 to IPv6, so DHCPv4 and DHCPv6 actually differ in detail, but the basic process
remains the same. (The term DHCPv4 refers to the version of DHCP used for IPv4, and the
term DHCPv6 refers to the version of DHCP used for IPv6.)
DHCPv4 servers retain state information about each client, such as the IP address leased
to that client, and the length of time for which the lease is valid. In other words, DHCPv4
tracks the current state of DHCP clients.
