The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. ! Image The address of the slave is the optimal next hop address. Mixed automatic configuration experiment A distribution list is a tool used to control routing updates. It only filters routing information and cannot filter LSAs . Therefore: the distribution list is used in the distance vector routing protocol, and the route can be filtered normally in either in or out direction. But the work in the link state routing protocol is a bit problematic.

By default, CISCO IOS turns off this no-advertise , which means that the prefix will be included in Image Ip address 10.1.34.3 255.255.255.0 6to4 relay. IANA has assigned a 6to4 relay anycast prefix 192.88.99.0/24 specifically for automatic routing of 6to4 packets to the nearest 6to4 The same prefix is ​​obtained through different protocols, first than AD , and later than metric basic configuration Image Ip default-network 192.168.1.0 0 : Reserved; Image twenty two Image Image FastEthernet FastEthernet IEEE 802.3 Experimental configuration IP nodes can communicate,ccna 200-125 dumps latest, and communication is actually the process of data interaction. Data interaction requires network devices to help us transfer data between two communication nodes. When the router (or other Layer 3 device) receives an IP packet, the router will find out the purpose of the IP packet in the Layer 3 header. 1111 1110 0xxx xxxx !! Two ACLs are created above to match the routes that need to be treated differently. Manual configuration Interface FastEthernet0/0 ipv6 ospf 1 area 0 length BGP table version is 1, local router ID is 1.1.1.1 This mechanism is now useless.

Ipv6 enable // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 The configuration of R2 is as follows: Interface FastEthernet0/0 ipv6 enable Switchport access vlan 10 interface fast0/15 Ipv6 enable The configuration of R3 is as follows: Router#show ip route Route-map nat3 permit 10 match ip address 2 match interface serial0/1 [Start process exchange] Image Ipv6 address 2001:0001::FFFF/64 Interface tunnel 0 What happens to the two-way re-release of RIP to OSPF on R3 ? We assume that the configuration completed on R3 , the route 192.168.1.0 will be injected into OSPF by R3 , and will be updated to R1 , and then updated by R2 to R4 . At this moment, R4 learns this from both OSPF and RIP . Routing, what would it do? Of course, OSPF is preferred because AD is small, so in its routing table, the route about 192.168.1.
