The maximum number of seconds allowed before the HOLDTime router must receive a keeplive or update message The IGP routes into BGP when the associated Route-map settings OK Weight Since the flash space is very limited, it is recommended to store the file on the TFTP server. When deploying on a TFTP server, be careful to first create an empty file to correspond to the URL in the configuration command . This file is used for dhcp snooping bingding database writes (depending on the device). In R2 opened on loopback interfaces 2.2.2.0/24 ,ccnp switch blogspot, R2 both redistributed RIP into OSPF , they redistribute directly connected into OSPF Connect Ip detects whether the IP address in the ARP body is invalid or unexpected, such as 0.0.0.0 , 255.255.255.255 , and multicast IP address, which are considered invalid IP . SenderIP verifies whether the message is an ARP request or response . And targetIP only if the message is the ARP response will be verified when Ip dhcp pool BIND If the feature is not enabled on the local end, the data packet is either routed successfully or never routed out (discarded). * i We will ping 1.1.1.2 repeat 1 size 1500 , we will find that R1 directly sends an ICMP packet, no fragmentation, the message is as follows: Configuration command Next, look at RP , SW2 has two interfaces, both of which will receive BPDUs , all from SW1 , so the cost of the first two BPDUs to root is 0 , equal; the sender ID of the sender is due to the same switch, and therefore equal, less out; and then compare the two BPDU port ID , that is, SW1 on both port interface ID , we assume that the two interfaces equal priority, then the ratio of these two ports The interface ID , and finally select the root port F0/1 on SW2 .
