Ip address 10.1.34.4 255.255.255.0 OR1 configuration Interface Loopback0 Distribute-list 1 in 1111 110x xxxx xxxx On R3 : Common basic configuration As shown above, based on the previous experiment, we used the Linklocal address between R2 and R3 to establish a neighbor relationship: Note that the Linklocal address here : FE80::5EFE:202:202 is an ISATAP format address, the last 64bits are PC (using router emulation) uses stateless auto get address: ipv6 address autoconfig default Experimental phenomena: In an IPv6 over IP manual tunnel, the local tunnel and the address of the peer tunnel are configured on the two ends of the tunnel, that is, the two dual-stack routers. Therefore, the scalability is poor. To facilitate the deployment of manual tunnels on IPv4 networks, the IETF defines a tunneling proxy mechanism. ! Image RS requires the router to generate RA immediately Image Then the routing table of R2 is as follows: On the network, the data is sent to 2002: CA65:1703::FFFF (next hop, which is the tunnel 6to4 address of R3 ) Image A quick look at: FF02::1 FF02::2 FF02::1:FFC4:0 OSPF , but R3 ignores this route (locally configured with a static summary route pointing to null0 ), although the LSA is still passed to R5 , which means that although R5 still has a 1.0.0.0/8 route,ccna r&s dumps 2017, the packet After being thrown to R3 , it is finally discarded at R3 , so there is still a problem here. Experimental procedure Ipv6 address 2001:0003::FFFF/64 ipv6 rip RIPprocess enable Local Not advertised to any peer Local At infinite Image Address-family ipv6 Now we are configuring ISATAP on the ISATAP host. Generally speaking, the IPv6 protocol stack is installed by default on the WIN7 system. By default , there will be an ISATAP virtual network card. After we configure the IPv4 address of the physical NIC of the PC , such as 1.1.1.1/24 , the ISATAP virtual NIC will automatically calculate the special interface identifier as described above based on this IPv4 address: 0200:5efe:1.1.1.1 , pay attention to this The format is equivalent to 0200:5efe:0101.0101 . On the windows system, we can see the simple way of writing the former.
