ccnp switch managing mac address table

The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. Ip dhcp snooping limit rate rate 0 100 0 100 i Route, and redistribute the route into its own OSPF process 2 , then R3 will learn this route from process 2 , assuming R3 learns this first 1 i By modifying the weight to influence the routing decision When an activation of the Port-Security on the interface, MAC number of addresses has reached the maximum safe number of address configuration, and has received a new frame, and the source of this data frame MAC is not in these security addresses, then start punishment Metric LocPrf Weight Use a hold-down timer to prevent routing loops Network 100.0.1.0 mask 255.255.255.0 200 65 Note that community is not sent by default and must be send-community . Received a Layer 2 frame. AFI (Address family identifier) Routing feedback 42 ! Portfast,uplinkfast, backbonefast Note that the main TC while timer is timed on the port, and the BPDU sent by the port will be set by the TC bit ,ccnp switch managing mac address table, and the BPDU will also be sent out from the root port. 10.1.13.1 C 192.168.12.0/24 is directly connected, Serial0/0 1.0.0.0/24 is subnetted, 1 subnets A the LLC sublayer own data to be transmitted is encapsulated, wherein the DSAP byte is filled B return to the SAP , the SSAP bytes are filled to their open the SAP , and then sent to MAC sublayer. Confirmation of TCA ( MSB set) to the previous switch. When the root receives the TC , it sends the TCA back to the original sending switch and sends the TC ( LSA set) to all bridges . Switch receives ROOT issued to TC after, will MAC aging time address table is reduced to 15s In the output of Show and more , you can use the pipe character | with a regular expression to filter the output. The processing of the DHCP packet of option82 . 4. Proposal/Agreement Sequence Request specific routing information: When it is necessary to know the information of a specific route or some specific routes, the request message will be sent together with the routing entry of the specific address. The device that receives the request will process the entries one by one according to the request message and form a response message. Note that the BGP created by R3 uses the AS number of 64512 , which is the federate member AS number instead of the federated AS number. 10.1.12.2 Then PC ping 10.1.13.0 , the data goes R1 ; Port Mode Encapsulation Status Native vlan Fa0/20 on 802.1q trunking 1 Neighbor 10.1.12.1 remote-as 13 advertise-map and summary-only when combined, Aggregate-address lower address all the details are summarized suppressed while advertise-map entries that match all the details if hung up, the summary route disappeared, (so long as advertise-map matching There is one in the detail, the summary is in); and the summary route inherits only the BGP path attribute of the advertise-map matching detail route.
