These two types of MACs are integrated in the network card. When the network card is initialized, the auto-negotiation is generally performed. The operation mode is determined according to the result of the auto-negotiation, and then the corresponding access MAC is selected according to the operation mode . Bibliography AD value and back door Network Fine routing Ip community-list 11 permit 100:11 route-map test permit 10 OSPF Experimental phenomena: ADJ-RIBs-IN stores unprocessed messages from peers. The included routes are all available routes RIPng 39 After the data transfer is completed, A to B transmits a data frame to tell B releasable attachment, the communication ends. Route . 1 : the AS_PATH : 100 the MED : 200 is External RouterID : 1.1.1.1 Inject-map to use the route-map in Ip community-list 11 permit 100:11 Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle . This will bring some hidden dangers to the loop. Therefore,ccnp route bgp lab, the route reflector needs to use the following two attributes to prevent loops: Active is local _100$ A CFI of 0 indicates a classic format. 0 , regarded as infinity All devices complete the basic configuration and establish BGP neighbor relationships. The yellow area is the federated member AS . Prefix-list 70 All dynamically learned MACs on this interface will be converted to a sticky mac address to form a secure address. Field name The IGP Origin, Metric 0, localpref to 100, Valid, Internal, Best Originator: 1.1.1.1, the Cluster List: 2.2.2.2 Configure the secure address of each interface ( Secure MAC Address ) RIPv1 200 300 Port-security supports private vlan MAC address is 0007.b400.0102 (learnt) Owner ID is cc01.043c.0000 basic concept VLAN isolated from each other, the broadcast can not cross VLAN communication, and therefore a different VLAN devices unable to reach between the general, different VLAN need to communicate with each other between the layer 3 device [Experiment 1 ] There is a main class route; there is a default route, and the main class route is taken. Peer group Store the result of the CRC cyclic redundancy check 100 i We found that both routes are best and are loaded into the routing table. Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 Internet address is 10.1.12.2/24 !! vlan10 activates DHCP snooping Configure OSPF unicast updates: This attribute may not be supported. Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. Looking at the above picture, we assume that both switches A and B run DAI , and both PC1 and PC2 get the address through the DHCP server. At this time, for PC1 , only the DHCP snooping database on switch A has its IP+MAC . Bind, switch B does not. Thus, if A and B interfaces between the DAI the untust , from the PC1 of ARP packets, the switch will be B discarded, because it is believed these are illegal packets, this way, PC1 and 2 communications on the problem It is. It is recommended that A and B interfaces are provided between the DAI ofTrust .
