*>i100.0.2.0/24 $ BGP routing table entry for 11.11.11.0/24, version 5 When R2 is configured with no validate-update-source ,ccnp switch 7.1 final exam, R2 will not verify the RIP update message source, so R2 will accept R1. * 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 Then PC ping 10.1.13.0 , the data goes R1 ; Then the NH of this BGP route is the interface IP of the announcer . EBGP neighbors generally use the other party's direct interface IP to refer to the neighbor . However, if the EBGP neighbor is established by using the LOOPBACK interface , the NH is the update source address of the EBGP neighbor. (Of course, the EBGP neighbor does not use the LOOPBACK interface to establish a neighbor.) Network Next Hop Metric LocPrf Weight Path ! STP operation [Results] There is only 1.1.1.0 route in the routing table on R2 . http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/pvlans.html 100 i When port-security mac-address sticky is activated on the interface , then: Router ospf 100 For example, the following three types of point-to-point transmission services: Configure the maximum number of secure addresses allowed for Port-Security . Obviously, the DHCP server is aware of the above problem, and the action it takes is to ignore this DHCP request. Therefore the PC cannot get the address. Each router running RIP manages a routing database that contains routing entries to all reachable destinations on the network. These routing entries contain the following information: The WEIGHT attribute is a CISCO private attribute. The scope is this router (not passed), the value is not included in the update Redirection enabled 0 100 0 100 i ? Go ahead and assign the interface of SW1 and SW2 to the PC to vlan10. Automatic summary From this experimental analysis, the automatic aggregation of BGP is obtained , and the main class network boundary is not required, which is different from the IGP . 100 i 10.1.13.1 CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. ------------------ 00:B0:64:04:09:99 e The secure address formed by the dynamically learned MAC is valid. If the MAC is in a failed state within 50 minutes (for example, the host is offline), the secure address is cleared after the aging time expires. Version How to judge whether there is arp spoofing in the intranet The DA 40bit multicast address is used to indicate that this FRAME is an ISL . Sent from the root bridge BPDU number of seconds after (this BPDU survived for how long), each through a bridge are minus 1 , so it is essentially the number of hops to reach the root bridge. If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. [Experiment 7 ] There are subnet routes (no match); there are default routes 8 bits The MAC sublayer is physically layer-dependent, that is, different physical layers have different MAC sublayers for access. In Ethernet, there are two main types of MAC : PAgP mode: We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows The process of processing a VLAN frame by a trunk port is as follows: The configuration is as follows: Neighbor 10.1.12.1 remote-as 100 Vlan 10 Vlan 10 10.1.12.1 from 10.1.12.1 (1.1.1.1) CLISTER_ID , then the RR will ignore this routing update. R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: 10.1.13.1 4 3 This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 , connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF . BGP is designed to AS transfer routes between, so it is actually a hop AS . Note the changes here: When R2 passes the route of 30.0 to R1 , the seconday AS number is no longer inserted .  open Experimental example: Called when republishing The configuration is as follows: Optional parameter contains an optional list of parameters, each parameter is represented by a length . 1 th 8 -bit group type field, a length 8 length field bit group and the value field contains a variable length parameter composition.
