Implementation of CEF For Windows 7 systems, the IPv6 protocol stack is already installed by default . Type echo protocol ipIcmpEcho 10.1.1.2 source-ipaddr 10.1.1.1 frequency 10 How does the prefix announcement work? LSPID !! Sends a distribution update action to a RIPng interface to perform a distribution list. The interface must be in the in/out direction. The interface is optional. If no interface is configured, the interface takes effect. Image After being injected into EIGRP , the tag is still carried. Neighbor 2.2.2.2 length // in R3 is only 1.1.1.0 route, that distribute-list 1 out here this command, all externally injected into the ! Neighbor Notification ( NA ) Redistribute bgp 234 R2 the original IPv4 header packet replacing IPv6 header, and then transferred to A . Which exchange method will be used !! Match the exit of the packet 2001:2::/96 , this 96 -bit prefix is a predefined prefix for NAT-PT operations. The prefix can be customized, but the length must be 96 bits . This predefined prefix is ​​very critical, which is equivalent to pre-defining an IPv6 space for the IPv4 network on the right side of R2 . To give a very simple example,ccna exam, IPv6 single network protocol, if there are PC you want to access IPv4 single-protocol network PC , so a quick visit? What is the destination address? Can not let a IPv6 only the PC to ping an IPv4 address, right? So this /96 pre-defined prefix comes in handy, which can be understood as a predefined IPv6 address space served in the scenario for the IPv4 only network on the right .
