Next Hop parameter Network 100.0.1.0 mask 255.255.255.0 // The offset value is increased by the value displayed in the normal route entry. It is added on the original basis instead of replacing the original hop count. Must be zero Then, in order for R3 to dynamically learn the routing of production and office servers, it is now necessary to redistribute these two static routes into OSPF . Of course, there are tricks when re-publishing. The frame to which the Native VLAN belongs is not tagged when it passes the trunk . Implementation of CEF Into, both are indispensable, such as 192.168.1.0/24 and 192.168.1.0/25 , although the network numbers of both are the same, both are 192.168.1.0 , but the two are definitely two different routes, two different Routing prefixes because their prefix lengths are not the same. 5.5.5.5 Longest match principle 10 Migrate to the Established state if you receive a keepalive message from the other party Unicast update When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. Redistribute rip metric 10 subnets distribute-list 1 out rip In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: 2 ! ! Automatic generation Initially, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 ,ccnp route simplified pdf, then we can configure it on R2 as follows: Dhcp-snooping A macro command that specifies the interface mode as access and enables the portfast feature. : 1 to 3 10.1.34.0 is directly connected, Serial0/1 ? Show pvlan mapping So they will be put into the IP global routing table, labeled B . The port mac of the Layer 2 switch is used here :) We can let DAI do further verification by configuring some additional options . There are three optional keywords, dst-mac , ip , src-mac * i100.0.2.0/24 Receiving behavior 4.3.3 Certification 36 Next hop 10.1.12.2, FastEthernet0/0 valid adjacency Set the interface to nonegotiate and do not send DTP frames. If the configuration is non-negotiated, you must manually configure the interface mode as access. The NEXT_HOP summary route is 0.0.0.0 (because the summary route is generated locally) We mainly analyze: Other uses After Port-Security is activated on the interface , the interface has certain security functions, such as limiting the maximum number of MACs of the interface (connected) , thereby limiting the access host users; or limiting the specific MAC to which the interface is connected . Thereby achieving the restriction of accessing users. Then to perform filtering or limiting actions, you need to have a basis, which is based on the secure address – secure MAC address .
