Logical aggregation of similar links The BGP update package is as follows. You can note that the length of the AS is 2 , which is " 300 , 100 ". Note that this is an ordered list of ASs . IP routing table ( IP Routing the Table ) Community-List. 11 the permit IP no-export (or no-export into NO-ADV ) (Note that in the actual environment, the situation may be quite different). R3#show ip bgp summary Activate the portfast feature for a specific interface ( Well-known mandatory ) Set community no-export additive After the DAI is enabled, if the downlink PC sends a large number of invalid ARPs in a period of time , it may cause a large loss of switch performance, that is, The BGP router appends its AS number to the AS_PATH only when the update message is sent to another AS ( EBGP peer ) . This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router, and the policy of modifying the AS_PATH for the IBGP neighbor is invalid. Redistribute BGP 1 subnets route-map BGP2OSPF1 Length, or mask length. When paired with the above ACL , some students will even write RIP-2 MD5 Authentication ( 20s time), start to enter the listening state Configuration Revision 17 Switch# show vtp password r >i1.1.1.0/24 If the interface is trunk , set the trunk protocol type Total number of bindings: 1 For example, in this example, we want to inject, the metrics of the two routes 192.168.1.0 and 192.168.2.0 become 2 hops, and 3.0 becomes 5.5.5.5 Vlan 100 When the route-map is executed, the match statement contained in the policy-list called by it will be traversed and the match action will be executed . On: channel member without negotiation ( no protocol ) After 10.30.0 is passed to R3 , since the RIP updated subnet and the R3 interface subnet belong to the same main class network, R3 receives the update, and uses the interface mask as the mask of the RIP route, so the R3 routing table The route loaded in is: 10.1.20.0/24 As shown in the figure, R1 and R2 open the LOOPBACK interface with the addresses 1.1.1.1 and 2.2.2.2/24 respectively . Set the channel-group ID 90 WWW and SMTP belong to the Isalated VLAN , so they cannot access each other; WWW and SMTP servers can only communicate with the promiscuous port, that is, with the router. When the routing policy changes, the neighbor is requested to re-advertise the route ( BGP does not periodically send updates) Note that although the interface configured with portfast is in the no shutdown or the link is up , it will jump to the forwarding state, bypassing the listening and learning , but the interface recommendation must be connected to the router or PC . If the switch is connected,ccnp route 642-902 vs 300-101, this interface still accepts the calculation result of spanning-tree . If the result of the calculation is block , then the interface will still be blocked . That's why you type this command on the CISCO IOS , IOS will prompt you, saying that it may cause a short bridging loop.
