R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC . In fact, this is an ARP spoofing behavior: ) Knowledge point * i100.0.1.0/24 Tag 9, type extern 2, forward metric 64 On R1 , filter out 11.11.11.0/24 routes, other release When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 The possible values ​​for the first column are as follows: The above command creates a policy-list ; the Policy-list can only contain a match statement. When a link needs to carry multiple VLAN information, you need to use trunk to implement Edge port edge ports * 172.16.0.0/16 is variably subnetted, 4 subnets, 2 masks S* 172.16.0.0/16 [1/0] via 172.16.3.0 Policy-list concept Configure OSPF unicast updates: Trunk configuration Optional non-delivery At this time, on R4 , only 1.1.1.0/24 and 192.168.13.0/24 can be learned. Multicast packets, one for each address that was learned on the interface. You can limit these bursts of multicast traffic by reducing the max-update-rate parameter (the default for this parameter is 150 packets per second). However, if you enter zero Station-learning frames are not generated, so the spanning-tree topology converges more slowly after a loss of connectivity. Mode Active is local ? Passive-interface configuration 51 ^a.$ Detailed rules If it is injected through the aggregate-address command, next-hop is equal to the update source IP of the summary router . description In direction Policy-list Next Hop Origin Route-map overview 192.168.1.0/24 Vlan range Vlan 10 The range of TAG values ​​in the external LSA ? Process exchange 8 bits Route-map LP permit 20 match ip address pref 2 set local-preference 100 Start a TCP connection. Prepare enough resources when BGP is enabled If the route is learned from other neighbors, the default value (locally the route) is 0. * i In general, we believe that the attack behavior is mostly from the terminal's PC , which may be poisoning or hacking. Therefore , the interface connected to the terminal PC is configured as a DAI untrust interface, and the interface between the switches is configured as a trust interface. / / Use this command to delete If the router accepts the parameters of the neighbor in the OPEN message, it will answer a keeplive message, and send the message for the period of 1/3 of the holdtime (but not less than 1S ). CISCO defaults to 60S . If the hold time is 0 after negotiation , the keepalive keep-alive message is not sent . As a result , the BGP table of R5 becomes as follows: Decision making If the above into OSPF , is invalid, i.e., the static route is associated interface, in OSPF the network when the network routing number, and will not be declared into OSPF . 100 i Document number One thing to note here is that ip bgp-community new-format is used to convert the display format of community in CISCO IOS . When using regular expressions in the extended community-list list, the filtering results will vary depending on the format choice. PVST+ has been improved in this respect. PerVLAN means that a VLAN corresponds to a spanning tree. In this way, the switch will calculate the spanning tree based on the VLAN . We can adjust the priority and other related parameters by using a separate VLAN spanning tree, thus affecting Spanning tree calculations ultimately achieve reasonable link bandwidth utilization. For example, in the above figure, there are two VLANs , 10 and 20 on the intranet . Let SW1 become the primary root of VLAN10 (the lowest priority of the whole network switch), SW2 becomes the secondary root of VLAN10 , and SW3 has the highest priority, so we will BLOCK off. SW3 is connected to the upper port of SW3 . In contrast, VLAN 20 is also the most specific adjustment. In this way, the user of VLAN 10 will go out to the left link,ccnp 300-115 syllabus pdf, the user of VLAN 20 will go to the right, and the link is properly used to achieve load balancing.
