In a DHCP snooping environment (deployed on a switch), we consider ports as either trust or untrust , which is a trusted or untrusted interface. On the switch, configure the interface connected to the legal DHCP server as trust . Only received on the trust interface Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federated EBGP routes in federated EBGP and IBGP *> 1.1.1.1/32 10.1.23.2 65 0 12 i FastEthernet1/0 There are classes and classless route lookup mode After deploying DAI , we can define the trust status of the switch interface: trusted , or untrusted , for trusted ports, it will not be received. IGRP/EIGRP Can not contain s> 172.16.11.0/24 Network 100.0.2.0 mask 255.255.255.0 neighbor 10.1.25.5 route-map test out BGP routing table entry for 11.11.11.0/24, version 5 Configure channel-group on the interface. 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: In this way, TC messages are quickly flooded across the network. Instead of using 802.1D , pass the message to root and then root Origin IGP, metric 0, localpref 100, valid, internal, best Originator: 1.1.1.1, Cluster list: 2.2.2.2 [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships, but the network segment where it is located will still be declared into the routing process. Route tag Tag 73 Port Convergence comparison between 802.1D and RSTP The DAI is deployed on the switch to ensure that legitimate ARP requests or responses are released and illegal ARP messages are discarded. The main actions of the switch after deploying DAI are as follows: Please see the passhot of Black passhot" IPv6 Notes", visit passhot.com for the latest version. Message type Recognized self-determination Ip sla monitor schedule 2 life forever start-time now 4.4.4.4 BGP Policy Accounting If R1 starts auto-summary and introduces 1.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. 100.100.100.0 [20/0] via 10.1.23.3, 00:02:57 100 i R2#sh cef interface s0/0 policy-statistics input Serial0/0 is up (if_number 4) The secure address entry can be configured by using the MAC ( SecureDynamic ) dynamically learned by the port , or by manually configuring the interface ( SecureConfigured ) and the sticy MAC address ( SecureSticky ).

Fortunately, we have two measures to help solve the problem, 1 is the route reflector 2 is federated. DAI - Dynamic ARP Inspection Etherchannel port does not support pvlan OSPF re-advertises routes to IBGP The configuration of SW2 is as follows: In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. 1,10,20,30 The time interval between listening and learning states. Default 15S The default load balancing method is round-robin Reference material View command: Show eth 1 summary / show ip route / show ip int brief R3 and R5 both advertise the routes of the same network segment to R4 . If the first eight rules cannot be determined, if R4 is configured: The boundary will change, so if you make an AS_PATH modification policy for IBGP neighbors , it will be nonsense. Switch(config-if)# switchport mode trunk Switch(config)# interface vlan 255 OSPF Use the global configuration command: err-disable recovery psecure-violation Ge ge-value Port The maximum time allowed before a KEEPLIVE or update message must be received . If Holdtime is inconsistent at both ends , both parties accept a smaller time. SW2 and SW3 are similar situations; note that at this point we are not allowed to do any static configuration of the allowed vlan configuration on the trunk port.
