Topology change process Continue to look R4 result of the capture ( R3 distributed to R4 of BGP update package): Database , this database is DHCP Snooping listens for DHCP information recorded after the interaction, inside contains the client's IP , the MAC , belongs to VLAN -related information, etc., and this information, just as ARP 's legality verification. PS : It should be noted that there will be class and classless route lookup methods, which are distinguished from classful and classless routing protocols. RIP and OSPF re-release Configuration Revision 17 BGP table version whenever the BGP table changes, this value is +1 2. Pass the RIP update with an unnumbered address ( invalid source ) ARP ACL and relative priority of DHCP snooping database entries R4 and R2 , we look R2 , R2 moment from R4 has learned this RIP routes, if it from the R3 also learn the route and of the route metric is smaller, then, R2 will preferably from R3 this Routes , so that R1 , R2 , and R3 form a routing loop. TYPE DHCP-SNOOPING VERSION 1 Preemption enabled, min delay 30 sec SW3 immediately aging the BPDU stored on Fa0/3 , and port Fa0/3 enters the listening state and starts to send BPDUs. Bridge ID in the MAC , is the backplane of the switch MAC , the port ID in the MAC switch port MAC , all the view switch mac available Note that the routes introduced outside the federation, the next-hop attribute will not change within the federation, even if it is passed between different member ASs , so R3 and R5 need to modify the next-hop attribute for R4 , set For your own update source IP , you already know how to do this? When no BPDU is received for a period of time and the lifetime reaches MAX age ,ccnp route manual pdf, the bridge considers that the port is connected. Virtual-PPP Virtual PPP interface Virtual-Template Virtual Template interface Ip community-list 11 permit 100:11 Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: Show ip dhcp database Displays recent activity on the DHCP database If the aggregate-address does not contain any keywords, the details are also passed, and the summary route is also passed. The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing. Access-list 1 permit any route-map PBR permit 10 match ip address 1 Total number of bindings: 1 Mode Holddown timer expired For the contents of this section, please refer to the relevant chapters of the path properties of this document. Ip dhcp pool BIND Origin file flash:CCIE.txt Vtp pruning is off by default Default route FastEthernet0/0 Router bgp 64512 no synchronization no auto-summary MacAddress / / Mark the routing table 192.168.1.0 as the default network When the previous eight routing principles fail to optimize the optimal route, and the maximum-paths [ibgp] n is configured under the BGP process , and the value of n is 2-6, the equivalent load balancing will be performed. In SW3 created on 10 , 20 , 30 three VLAN Via 10.1.13.3, FastEthernet1/0, 0 dependencies Router bgp 345 In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. Paths: (2 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 IBGP established between neighbors neighbor, in order to ensure the stability of neighbor relations, general use loopback interfaces to establish, because if you use the physical interface, the physical interface failure, neighbor relations DOWN up, and AS inside, the path may be redundant LOOPBACK routes between neighbors can be obtained through IGP and provide some routing redundancy (when physical lines are also redundant). When establishing a BGP neighbor relationship using the loopback interface , be sure to specify the source IP address to be updated .
