If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. OSPF . In this way,ccna course dumps, for R4 , it goes to 192.168.1.0 , there is a sub-optimal path , that is, around the long way, take R2-R3-R3-R5 Image In R1 the ip route 0.0.0.0 0.0.0.0 null 0 then re-released in a static routing process, but also to Set ip next-hop verify-availability 10.1.1.2 10 track 1 At infinite Image 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . Image Image Via FE80::FFFF:FE10:5, Serial0/0 OI 2001:1:2::1/128 [110/192] No passive-interface fast 0/24 Ipv6 router ospf 100 ! The configuration of PE1 is as follows: Image Metric: 0 Image Ipv6 mld join-group ff04::1 Whether to support on-demand circuits 192.168.2.0/24 !! 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. Interface Serial0/0 ipv6 enable IPv6 basic experiment LocPrf IP address, and then take the destination IP address to look up in its own routing table. After finding the "best match" entry, the packet is forwarded according to the outbound interface or next hop IP indicated by the routing entry . This is the IP route. ( IP routing ) . And each router maintains a routing table locally. The A record in IPv4 is used to map the host name to a V4 address, and the AAAA resource record maps the host name to an IPv6 address. We can do a test: Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 Internet address is 10.1.12.2/24 You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface . Tag Ipv6 router ospf 100 OR2 configuration Ivv6 nat v4v6 pool v4v6-pool 2001:2:: 2001:2::FFFF:FFFF prefix-length 96 ipv6 nat v4v6 source list 1 pool v4v6-pool Ip route 0.0.0.0 0.0.0.0 192.168.23.3 696 [Two times of prefix] ...... The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as: Dynamic NAT-PT description Image Image Now we configure it on the ISATAP router. The IPv4 address assigned to the router is 2.2.2.2/24 , and a IHL header length; Policy-based routing is more powerful and flexible than traditional routing. It allows network managers to select forwarding paths based on destination addresses and packet types, packet sizes, applications, or IP source addresses. Interface vlan 20 Let's start with the above picture, starting from 172.16.0.0/16 . The next network number we see is 172.16.10.0/24 , which is obviously obtained after applying the VLSM variable length subnet mask. a 172.16.0.0/16 a master class this network subnet . So the so-called subnet, we can understand as a network number obtained by "stretching" the mask or borrowing from the host bit based on the default mask length of the category to which the network number belongs. In fact, 172.16.0.0/16 is an interval that includes 172.16.10.0/24 .
