None does not send updates ( passive ) Last update from 192.168.101.10 on Serial0/0, 00:12:46 ago Routing Descriptor Blocks: Option packet structure: ORIGINATOR_ID and CLUSTER_LIST are optional non-transfer attributes used by route reflectors to prevent loops. See the " ORIGINATOR_ID and CLUSTER_LIST " BGP Properties section of this document for details . Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 1.0.0.0/24 is subnetted, 1 subnets Switch(config)# vlan dot1q tag native V1 defaults to send v1 to receive v1, v2 The length is 2 bytes, indicating the frame type. When the value is 0x8100 , it indicates an 802.1Q Tag frame. If a device that does not support 802.1Q receives such a frame, it will discard it. 8 bits Sw(config)#vlan 202 Experimental verification Note: If it is an EIGRP environment,ccnp switch 642-813 vs 300-115, you need to implement unicast update, then the route update interface can not be PASSIVE (this is different from RIP ), directly use the neighbor command to specify the neighbor. If the interface is PASSIVE , even if the neighbor is manually specified , the EIGRP neighbor relationship cannot be established normally . Once the ORF is deployed , the BGP peers will negotiate the ORF capability in the open message when the BGP peer relationship is established . If the negotiation succeeds, the ORF content is pushed using the route-refresh packet . These are all done by VTP pruning auto-negotiation. Address 10.1.12.1(10) Vif PGM Multicast Host interface By default, this database is dynamic, which means that when the switch is restarted, all entries in the database are lost. The result of this event may cause network disruption. So we can store this database as a file, this is the DHCP snooping database agent . The configuration command is very simple, global command: Switching, and store the information in the cache, all subsequent data packets , you can not interrupt the system processor to perform queries and other operations , directly from In the above figure, there is a Layer 2 link between the customer and the carrier network. If the client's device is elected as the root bridge for some reason, it is troublesome. Therefore, the rootguard feature can be used to connect the client to the interface of the carrier. Deploy on. Then when these interfaces receive better from the customer Y Revision record SW1(config-if)# ip address 10.1.1.253 255.255.255.0 Metric Retaining the NEXT_HOP attribute outside the federation within the federation Y Redistribute external routes into the IGP to ensure IGP synchronization with BGP . However, the drawback of this method is that if a large number of routes are obtained from BGP , it is a considerable burden for the IGP . After completion of the above-described basic configuration, we can at R5 to see the phenomenon, R5 simultaneously from R2 received 100.0 route segment, also from R3 received from the R1 release of 100 route segment, the final R5 will The route of R2 is preferred , which is matching this rule. 3.3.3.3 100 <1-99> Community list number (standard) Note 21 Dampening takes effect only on EBGP routes and invalidates IBGP routes.
