Remove the command configured on SW1 in step 2 to restore the experimental environment. Received a Layer 2 frame. *>i Because ARP 's response does not need arp request is a prerequisite to send directly, so an attacker can construct arp reply message is sent to the target of attack, to refresh the attacker's arp table, to achieve the same arp deceitful purposes. Port-Security Run RIP between R1 , R2 , and R3 , and R1 and R2 are injected into their respective loopback ports. The next hop of 1.1.1.0/24 , because the AD value of OSPF is better than RIP . Len : Number of bytes of Sub-option Value , excluding two bytes of SubOpt and Len fields BGP table version is 3, local router ID is 3.3.3.3 Private VLAN concept Invalidation timer OSPF redistributed directly connected interface default cost20 ; redistributed static route default cost20 ; using the default-metric can modify and redistribute static routes into other routing protocols OSPF default after the cost , but this command to redistribute directly connected interface. invalid. Determine if the frame has a VLAN tag . Match 100 , 1400 , 300 400, etc. Affect traffic 12 by modifying the LOCAL_PREF attribute !IP address VTP version running VTP Domain Name VTP Pruning Mode VTP Traps Generation Too many neighbors, managing these IBGP adjacencies will be a challenge and burden the device. Fortunately, we have two measures to help solve the problem, 1 is the route reflector 2 is federated. Received WAS, IT A SENDS that the LAN containing the BPDU DATE The up-to-Port Information Stored for that. the In the this Way, the inferior IS Discarded Information, and Superior Information The IS ON propagated Network. " Local origin Then all the 172 network segments on R1 and R2 are suppressed. At the same time, since the route-map test only matches the 1.0 and 2.0 network segments (in AS100 ),ccnp switch test cost, this summary route, AS_PATH only inherits AS100 , which is 300 100 ; TCP/IP volume one Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Two modes of operation: normal (the default) and aggressive R3 summarizes the details of R1 and R2 (summary command plus AS_SET keyword), so that the BGP summary route generated by R3 inherits the detailed AS_PATH attribute, and the packet capture on R4 will find the summary route. = 300 {100,200} AS_PATH : look at the results of the capture, found article summary route AS_PATH attribute consists of two parts ( segment ), the value 300 that the segment is The dst-mac detects the received destination ARP packet. The destination MAC address of the Ethernet frame header is the same as the target MAC address in the ARP body . This check is for ARP response . When this option is enabled , ARP packets are discarded if the two MAC addresses are inconsistent. It can be seen that since we configured the summary, the as-set keyword was used to make the summary route inherit the detailed partial path attribute. Therefore, the generated summary route still retains the aggregate attribute, but there is no atomic-agg attribute. Obviously this attribute It is no longer necessary in the case of the as-set keyword. On R2 , going to the 100 network will use R1 and R3 as the next hop for equal load balancing (although R3 's uplink port has smaller bandwidth, but it is directly connected). Route . 3 : the AS_PATH : 500 the MED : 150 External RouterID : 172.16.13.1 Router ospf 100 2 : Clear text verification; When the switch receives suboptimal BPDUs from other designated switches or root bridges , 802.1D encounters this situation by first ignoring these suboptimal BPDUs . Neighbor maximum-prefix xx restart 2 Packet-based load balancing and process switching. Process exchange is for each packet , the router must perform routing table query and interface selection , and then query the data link information. Because each process that determines the routing of packets is independent of each other , all packets destined for the same target network are not forced to use the same interface. In order to open the process exchange function on the interface , you can use the command no ip route-cache under the interface . For IPv6 nothing needs to be done , because by default the feature is turned on.
