A and B respectively use this IPv4 public network address to map to get the 6to4 address space. The 6to4 address space uses 2002::/16 , and the 6to4 address is formed as follows: The direct result of this command is that the metric of 192.168.12.0 in R3's original routing table is 30720 ,ccna dumps book, but now it is 10000 , which becomes 40720 . We see that after the offset command is configured , what actually changes is the DLY that is updated to the neighbor . Because it is true that DLY is the best, the default (interface) ip load-sharing per-packet When one or more consecutive 16- bit fields are 0 , the ::: is available, but only one is allowed in the entire abbreviation: 12 FE00 – FE7F On the other hand, we capture the package: Maximum route entry Access-list 2 permit 10.1.2.0 route-map cisco permit 10 Ipv6 nat FF02::1:2 = ALL DHCP Agents ( servers or relays, link-local scope ) FF05::1:3 = ALL DHCP servers ( Site-local scope ) Image Take the configuration of R2 as an example: FastEthernet0/0 The link layer supported by IPv6 requires a minimum MTU of 1280 bytes. So now, we add the following in the configuration of R2 : The configuration of PE2 is as follows: Source starts to send IPv6 packets using MTU=1300 , and the packets reach the destination smoothly. None !! Match the exit of the packet URL representation of the IPv6 address Address format: FF02:0:0:0:0:1:FFXX:XXXX , the specific correspondence is as follows: At this time, he himself will still forward if he receives the data packet to 3.0.0.0 , but will not forward to other rips. Address-family ipv6 neighbor 2001::1 activate --- Passing the value of Tag The destination IP address of the route , which can be the address of the natural network segment or the subnet address or The above command defines the source address allowed to be IPv6 nat , matching with an IPv6 ACL . Unassigned The configuration of R4 is added as follows: Then just republish this static summary route into OSPF . In this way , the routers in OSPF can reach through this summary route. Exit-address-family DC The IPv6 data of the 6to4 network can be forwarded by obtaining the corresponding public network IPv4 address from the destination IPv6 address . However, if the IPv6 island is not using the 6to4 address space, but a regular aggregatable global unicast address like 2001::/16 ? This requires the use of 6to4 relay.

If the RIP protocol is running in the network , in fact, for A , going to 3.3.3.0/24 can be shared by B and D load. However, in some cases, we hope to data is controlled, for example, we want to 1.1.1.0 Access 3.3.3.0 of the main traffic go B , when B hung up, then switch to the D on. So we simply in D deployment offset-List , in which the A notice 3.3.3.0 routing, increased 1 jump, then this route will be compared to B advertised to A route metric big a jump, A naturally preferably B .
