Ipv6 unicast-routing interface Serial0/0 encapsulation frame-relay Implementation of CEF Match ip address Neighbor 2001::1 activate Next Hop Basic knowledge The IPv4 public network address obtained by A is 132.214.1.10 , and B is 206.123.31.200 . 6VPE basic experiment Note that the IPv4 prefix 192.88.99.0/24 here should be published to the routing protocol on the IPv4 Internet. Otherwise this 6to4 relay using the anycast prefix is unreachable in the IPv4 Internet. Ipv6 ospf 1 area 1 Transition mechanism from IPv6 single protocol network to IPv4 single protocol network to sum up IPv6 transition technology Specify a smaller MTU=1400 in the ICMPv6 message. Here , the "high-order 32bits reserved for ISATAP " in the 64-bit interface identifier is described on Wikipedia: " The link-local address is determined by concatenating fe80:0000:0000:0000: 0200:5efe: for global unique To prove this again, we are on PE1 : ! A distribution list is a tool used to control routing updates. It only filters routing information and cannot filter LSAs . Therefore: the distribution list is used in the distance vector routing protocol, and the route can be filtered normally in either in or out direction. But the work in the link state routing protocol is a bit problematic. IPv6 transition technology Look at the above picture, the gray space 172.16.0.0/16 , this network number, we call the main class network number , the so-called main class network number, meaning the network number, according to the IP address category to which it belongs , corresponding to The network number obtained after the default subnet mask length. Such as 172.16.0.0 this is a Straight connector Manual IPv6 over IP tunnel Default route ACL Use the Linklocal address as the source address of the protocol packet and send a RIPng message to the neighboring RIPng router. Use FF02::9 as RIPng ! The configuration of R2 is similar. After the configuration is complete, the RIP messages are exchanged between R1 and R2 , and the unicast is performed, so that the PC will not be affected. 10.1.13.3 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,ccna dumps 2019, 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.
