// AS200 is the Primary AS and is used to configure the BGP process. Implementation of CEF We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows 12(_34)?_56 Then PC ping 10.1.13.0 , the data goes R1 ; For more detailed BGP state machine and neighbor relationship establishment process, please see the note document: " BGP State Machine and Neighbor Relationship Establishment Process" 2011-12 R1(config-router)# redistribute connected subnets Neighbor 2.2.2.2 peer-group IBGP_peers SW3#sh vtp st About PBR 80 When R2 is configured with no validate-update-source ,ccnp troubleshooting labs, R2 will not verify the RIP update message source, so R2 will accept R1. The configuration of R3 is similar. If R1 turns on auto-summary and network 10.0.0.0 , the subnet will be automatically summarized to R2. ORIGINATOR_ID is a 32-bit value created by a route reflector . This value is the IBGP routerID of the route initiator in the local AS . Note that this initiator is not necessarily the initiator of this route (there is experimental verification below), if the initiator finds its RID In the received route None / / This is used to delete the no-export attribute, is a list of commands basic concept Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself In the output of Show and more , you can use the pipe character | with a regular expression to filter the output. None Topology change mechanism (delivery) CLISTER_ID , then the RR will ignore this routing update. Send BPDU EIGRP / / Modify the default parameters Access-list 1 permit 1.1.1.0 201 200 100 ! Debug dhcp detail We found that the route to 100.0.1.0 and 2.0 , the next hop is 3.3.3.3 , because of these two paths, original Several problems with VTP Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
