Ip helper-address 192.168.100.1 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 . Note that there must be three layers between the DHCP server and the trunk interface. Because the unicast packet is relayed, the source address is the trunk interface configured with ip helper-address . Therefore, when the DHCP server returns the packet, the destination IP address of the packet. This is the interface IP of the interface configured with ip helper-address . Abc?d If both are open If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. Configuration example 1 ( -RIP in a single routing protocol environment ) i SW1 (config-if) # glbp 1 priority 120 !! Priority defaults 100 , the highest priority becomes the AVG , under equal priority, the maximum IP interface becomes the AVG . Default " AVG preemption" is off RIPv2 manual summary The configuration of R3 is as follows: Peer state name * 192.168.101.10, from 10.10.10.10, 00:12:46 ago, via Serial0/0 Route metric is 1, traffic share count is 1 The configuration of SW1 is as follows: 86025 As a result of the experiment, the PC could not get the address. Switch(config)# interface fast0/1 Switch(config-if)# switchport Switch(config-if)# switchport mode access Note that this time you add the extend keyword in the send-community Ip route 10.1.2.0 255.255.255.0 10.1.254.1 RIP version number: R2 RIPv2 Another recommended solution is to adjust the management distance of the routing protocol: 201 200 The switch that first recognizes the topology change sends the TCN , the designated bridge receives the TCN and immediately returns a normal BPDU with the TCA set. 100 2.2.2.2/32, version 55, epoch 0, per-destination sharing 0 packets, 0 bytes Not advertised to any peer Local Route-map test permit/deny 20 Route-map test permit 20 router ospf 1 BGP Exact match ORF The red font part of the above output is the layer 2 MAC information and so on. Metric =0 This command can change the properties of the aggregation route (note, only for the summary route, not for the details). Port Offset-list 1 out 1 serial 0/0 The MAC address is burned in the ROM of the Network Interface Controller (NIC ) . (interface) ip load-sharing per-packet Application example Y This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 , connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF . Local origin KEEPALIVE message Set community no-advertise route-map test permit 20 Promiscuous Router ospf 100 O 2.2.2.2 [110/65] via 10.1.12.2, 00:05:16, Serial0/0 The Control field is composed. 32768 1 command) only sends and receives v1 messages, v2 only sends and receives v2 messages by default . Same interface mode ( access , trunk ) PC2 is a new host access, arranged 192.168.0.1 address, the address after the completion of the configuration, PC2 transmits to the network a Gratuitous ARP , to prevent someone within the network using the same IP address, the Gratuitous ARP is senderIP and target IP All are themselves, senderMAC is its own MAC . Wherein SW1 is as follows: Sw(config-if)#switchport mode private-vlan promiscuous sw(config-if)#switchport private-vlan mapping 100 201,202 sw(config)#interface range fa 0/1-2 VLAN works on the second layer of the OSI reference model 10.1.13.3 Adj-RIBs-Out of Match abcd , abccd , abcccd, etc. Supplementary explanation of the role of the as_set keyword: As discussed above,how to book ccnp route exam, we did not deploy any strategy. In this experiment, R4 is preferred as 3.3.3.3, that is, R3 is the next hop to the 100 network segment. The reason is that the BGP RouterID of R3 is smaller than the RouterID of R5 . When BGP compares decision rules, it always compares to the RouterID, which is preferably small, so R3 is chosen .
