To configure globally, use the command: SW3(config)# spanning-tree portfast bpduguard default , which activates bpduguard on all interfaces that activate the portfast feature : 100 Neighbor 10.1.23.2 remote-as 200 Difficult to resolve There are 2 forwarders (1 active) Default-information originate In a real-world environment, an IP address is generally used to indicate the object of communication, and the function of ARP is to " resolve " the IP to the corresponding MAC address. Paths: (2 available, best # 2, table Default-IP-Routing-Table) Flag: 0x820 Match 100 , 100 200 , 100 300 400, etc. 100 Windows system), at the same time reply a Gratuitous ARP response to inform the peer that there is a duplicate IP address. Next hop 10.1.13.3,ccnp switch dumps 9tut, FastEthernet1/0 valid adjacency RIP-1 Only Show ip b rib-failure When the community attribute carried in the 11.11.11.0/24 route prefix is " 100:11 no-export ", we do the following test: IGP Match tag 10 10.1.12.0 [110/128] via 10.1.23.2, 00:06:40, Serial0/0 The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing.

BGP routing rules Show ip bgp dampening 100 i 200 300 Use the match command to match a specific packet or route, and set to modify the packet or route related attributes. 100.0.2.0 should choose R5 , check out the BGP table of R4 : As mentioned earlier, DAI performs ARP legality verification by means of the DHCP snooping binding database . Another basis for legality verification is the manually configured ARP ACL . Add configuration on SW2 : (global configuration mode) ip dhcp relay information trust-all basic configuration In R4 connected R2 interfaces capture found update package 11.11.11.0 attribute prefix is carried in the AS_PATH , content of AS 1 Next Hop ( 802.1D is always 0 ) 20 . Precautions: The RRs have physical connections and establish BGP peer relationships. In the case where one of the RRs fails, the client still has an alternate connection. Switch(config)# interface vlan 255 Let's take a look at R4. 100 Ip policy route-map PBR Incomplete Port ID of the BPDU sending bridge (priority + port number) ? Route-map defaults to permit , the default serial number is 10 , the serial number is not automatically incremented, and the serial number needs to be specified. When the interface is up/down , all dynamically learned MAC address entries will be cleared. The statically configured secure address entries remain. 17:57:27 The routing protocols that support TAG are: RIPv2 , EIGRP , OSPF , ISIS , BGP The configuration of R2 is as follows: This feature uses the CDP table of the device to determine the reachability of the next hop. Store the result of the CRC cyclic redundancy check Address family identifier. When the value is 2 , it indicates the IP protocol. 16 bits ? Note that the relay is in the configuration: Match the previous character 1 or more times Match abd , abcd , abcdefg, etc. 200 i After an ARP ACL , if ARP packets are denyed by the ARP ACL , these packets are directly discarded, even in DHCP snooping. Configuration and implementation The Fa0/0 interface is divided into two sub-interfaces, and the encapsulation protocol Dot1Q is configured . At the same time, the traffic is tagged with VLANs , so that a trunk is started between the switch and the router . The two sub-router interfaces are arranged two VLAN gateways in the IP , as VLAN user gateway. The above command calls the defined policy-list in the route-map ; multiple policy-lists can be called in a route-map . The secondary VLAN is mapped to the SVI interface of the primary VLAN , allowing for Layer 3 switching of pVLAN ingress traffic. 10.1.12.1 from 10.1.12.1 (1.1.1.1) The out- direction policy cannot be used separately for the member of the peer-group . It can only be used for the entire group . The in direction does not have this restriction. All neighbors in the same peer group must be all iBGP neighbors or all eBGP neighbors. Route-map DHCP overview SW3 is small), so the interface connected to SW2 on SW4 wins and becomes RP . We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Fa0/22 1-4094 R3 's gateway is R1 , R1 itself has static route to 2.2.2.2 , and the next hop is R2 . Note that this is an MA network. All three interfaces are on the same network segment. This is critical. R3 will go to 2.2.2.2. When the data is dropped to its own gateway 192.168.123.1 , R1 finds that the next hop of the data is 123.2 on the same network segment as the local inbound interface after searching through the routing table , so he thinks that 123.
