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 Binary prefix (high bits ) OK The IPv6 prefix reserved for NAT-PT . Then use the ipv6 nat prefix 2001:2::/96 v4-mapped v4map command to associate this ACL . In this way, when A accesses B , you can directly use the 2001:2:: CA65:6402 address to access B on the V4 network . Note that the prefix 2001:2::/96 is the IPv6 prefix reserved for NAT-PT . The latter CA65:6402 will be translated into an IPv4 address, ie Ipv6 unicast-routing Bgp router-id 3.3.3.3 Modify the AD value of EIGRP This fulfills the demand. Ipv6 nat Prefix readdressing R2(config-router)#redistribute rip subnets The summary of the route is actually done by the operation of the subnet mask. For the following example: RFC1058 MP-BGP UP The other bit is 1 to indicate that the host uses stateful address autoconfiguration to obtain parameters other than the address. If it is unreachable, the suppression timer is started at the same time. If the timer expires, the same neighbor still advertises the Set the outgoing interface of the data The front is to use static routing. If dynamic routing protocol is used, the situation is different. For example, IGRP or EIGRP , the network specified by the ip default-network command must be obtained through IGRP or EIGRP (declaration, learning or redistribution). ), the default route can be dynamically passed to other protocol routers. ............ Y Tunnel destination 10.1.23.3 Mpls ip The mask of the destination address. Image Vrf definition cisco rd 1:1 S* 192.168.1.0/24 [1/0] via 172.16.12.1 A quick look at: Routing strategy 0000 0000 xxxx xxxx Ipv6 unicast-routing Network 10.1.23.2 0.0.0.0 area 0 You can configure a CISCO router as a 6to4 relay with an arbitrary IPv4 prefix : Existing CISCO IOS of IS-IS supports IPv6 , the relevant RFC : 1195 In R2 on a simple look: Ipv6 address 2001:12::1/64 Passing the value of Tag The first 8 bits of the route must be exactly matched with the first 8 bits of 172.0.0.0 . The other bits do not care, and the mask length must be greater than 24. Note that here You can configure a CISCO router as a 6to4 relay with an arbitrary IPv4 prefix : 16 bits 13 R3 Invalid timer Metric =0 This is the general case, of course, there are two situations, it depends on the specific environment and the specific routing protocol. Prefix-delegation pool dhcppool lifetime 1800 600 MTU Image Route redirection version During the transition of the network from the IPv4 single-protocol network to the IPv4-IPv6 IS-IS router, this command maintains the IS-IS adjacency between IS-IS routers using different protocol sets . It prevents IS-IS routers that use different protocol sets from performing hello checks and losing IS-IS adjacencies. After the network switch or transition is complete,ccna cybersecurity operations dumps, you can configure the adjacency-check back.
