First come to know the first three-layer interface: SVI switched virtual interface, a logical interface of SVI , that is to say not a physical interface, when we create a VLAN on the switch , we can create a The SVI interface corresponding to the VLAN , for example, we created 5.5.5.5 Metric Distance 130 10.1.12.1 0.0.0.0 1 LocPrf Ip route 172.16.1.0 255.255.255.0 192.168.12.1 Access-list 1 permit 10.1.1.0 R1(config)# access-list 1 deny 172.16.32.0 R1(config)# access-list 1 permit any STP uses four parts to solve the Layer 2 loop: Now, we have to go through the calculations to get a summary of the segments that are just "inclusive". Ip route 100.0.0.0 255.0.0.0 null0 If there is an EBGP connection between R2 , then a routing loop occurs, and R1 and R2 will receive the summary route and accept the routing update. This is because this summary route does not carry any information about AS100 and AS200 . BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD , these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. Disable port On R3 : Timeout Configure abort timeout interval After completing the above steps, the logical etherchannel interface is set up. Network 5.5.5.5 0.0.0.0 area 0 So as long as the 1.1.1.0 network is not DOWN , R1 will always send default routes to R2 . After the DAI is enabled, if the downlink PC sends a large number of invalid ARPs in a period of time , it may cause a large loss of switch performance, that is, Set interface specifies how to send such a packet set ip default next-hop specifies the next hop to be forwarded set ip next-hop specifies the next hop to forward CISCO default MED is 0 , optional non-delivery another example The weight of the BGP route generated by the local summary is also 32768. Then you can use the route-map tool, that is, we can associate a route-map with the re-release , to implement the function I just mentioned. Ip dhcp snooping C 192.168.23.0/24 is directly connected, Serial0/1 In addition, if there are multiple links between two EBGPs and use their respective Loopback ports as the source ,9tut ccnp tshoot 300-135, you should also pay attention to the configuration. Ebgp-multihop 2 (because loopback spans two routers, including this one ), and must also refer to static routing to the other's loopback interface. ) Experiment 2 Route-map test permit 10 Router bgp 100 Weight Next Hop // This command is used to advertise the real AS number of the AS outside the federation . As a result, when PC2 sends data to its own gateway 0.254 , since the MAC of the gateway has been spoofed into the MAC of PC1 , the data is forwarded to PC1 , and PC2 is disconnected. If PC1 is smarter, transfer the data sent by PC2 to the real gateway, and run a message analysis tool locally to snoop the data sent by PC2 . Then, in the case of PC2 continuous network, God does not know. I feel the Internet traffic of PC2 , this is the man in the middle , the middleman attack.
