OSPFv3 ( RFC2740 ) So now, we add the following in the configuration of R2 : RIPV1 operational behavior OR2 configuration RFC2766 , RFC2765 . NAT-PT (Network Address Translation - Protocol Translation) is an address translation technique that translates IPv6 addresses into IPv4 addresses and vice versa. NAT-PT is based on the stateless IP/ICMP converter ( SIIT ) algorithm defined in RFC2766 . SIIT algorithm translation 011x xxxx xxxx xxxx Ipv6 nd reachable-time !! A neighbor confirmed after its accessibility by an event,ccna course in chennai, during which time the neighbor is considered reachable, the default 30S (in CISCO IOS on the show out, the book says It’s 30min , it’s estimated to be wrong.) Neighbor 2001:45::4 remote-as 234 The configuration of R2 is added as follows: Image Prefixing The configuration of CE1 is as follows: Image C UP A tool used to control routing updates can only filter routing information and cannot filter LSAs . The prefix list contains the serial number, matching from the smallest Ipv6 address 2023::3/64 ipv6 nd suppress-ra 0/0/0 This is the problem, how to solve it? Very simple, on the OR2 , deploy PBR , as long as the server data from Netcom, all forced to OR1 , it is solved. Last retransmission scan time is 0 msec, maximum is 0 msec 1/16 This address space plus the subnet ID can be assigned to the intranet users. In this experiment, our intranet users use stateless autoconfiguration to obtain the address. At this time, if there is a user under R1 to access the v6 network under R3 , then the destination address must be the 6to4 address space of R3 , and the data is up. Let's look at the above scenario, focusing on the egress router. This egress router is a three-layer link with the Layer 3 switch. Therefore, you need to configure the backhaul route to the intranet, which is the red font part in the above picture. In this scenario, There are only three network segments on the intranet, so three static routes are configured, but what if there are 100 network segments? Do you want to have 100 routes? As a result, the routing table becomes very large and bloated, which is very inconvenient to maintain and manage. More importantly, this undoubtedly wastes resources of the device. Therefore, from the perspective of network optimization, no matter what kind of network model, we need to keep an eye on the number of routing entries in the router routing table in the network, whether it is sufficient for optimization, and whether there is room for optimization.
