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). The PC belongs to VLAN 10 and the gateway is on SW2 . The DHCP server belongs to VLAN 100 and the gateway is on SW2 . Define matching criteria Tags When the ARP packet received by the interface exceeds this threshold, the interface enters err-disable . You can manually restore this interface by using the shutdown no shutdown method. Alternatively, use the global command the errdisable recovery to have the interface automatically recover after a certain time interval. Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Origin codes: i - IGP, e - EGP, ? - incomplete 10.1.13.3 2) Activate TC while timer , and then send the TC- set BPDU out from all non-edge designated ports and root ports . In this way, topology change information quickly floods the network. If the above is replaced by EIGRP , the phenomenon is the same as RIP , R1 will declare 1.1.1.0 into EIGRP. Distribute-list 1 out rip BGP Policy Accounting Focus on the configuration of GW : Match any single character, including spaces The maximum number of secure addresses, the upper limit allowed by different software platforms is different, but the default is 1 . Neighbor 5.5.5.5 update-source Loopback0 neighbor 5.5.5.5 next-hop-self 0 100 0 100 i R2(config-router)# distribute-list 1 in fa0/0 S0 192.168.12.1/24 r1 Go ahead and assign the interface of SW1 and SW2 to the PC to vlan10. PVST+ Flex links and Port-Security are not compatible with each other 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 DAI 's work depends on DHCP snooping Looking at the BGP table of R4 , we find that: ? Router ospf 1 Example 2 of ip community-list (logical relationship): The CISCO IOS version prior to 12.0(22)S and 12.2(15)T does not support this feature, and older IOS versions of the router restart exist. Configure the secure address of each interface ( Secure MAC Address ) ! None Set ip next-hop { ip-address [...ip-address] | recursive ip-address } Implementation points Ip prefix-list 1 seq 5 permit 100.0.1.0/24 ip prefix-list 2 seq 5 permit 100.0.2.0/24 route-map test permit 10 ( Well-known mandatory ) Interface FastEthernet0/1 switchport access vlan 10 Reissued by an early agreement like EGP Ip sla monitor 1 1) Clear the MAC entries learned from all interfaces except the one that received the TC BPDU . Although this action may cause a brief burst of flooding in the network, it is also beneficial to refresh the CAM table and clear the stale entries. 65 VTP mode On R2 : AS No. 16bit local AS Number Regular expression Route accurate summary algorithm Set tag 20 Ip arp inspection log-buffer logs number_of_messages interval length_in_seconds Router bgp 200 Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). When a secure address is configured on a Port-Security interface, and the MAC address of the secure address attempts to access another Port-Security interface in the same VLAN , the penalty is initiated. PAgP is a Cisco propretary protocol LACP is IEEE 802.3ad standard FastEthernet1/0 Protocol overview OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello. Timers 1 Note that if you attempt this time SW2 on F0 / 2 interface priority piecemeal, and it is useless, because the port is looking at the sender ID . So if on SW1 , the port priority of F0/2 is reduced. Then on SW2 , F0/2 will win as the root port. Community value (route), then how to write it? If you directly match no-export , it will match with 11.11.11.0 , so you should use the exact-match keyword. If configured on R3 as follows: Redistribute connected metric 10 subnets route-map test network 192.168.23.3 0.0.0.0 area 0 Metric 100 CISCO data forwarding mode 13 Burst interval ,ccnp tshoot final exam answers 2016, the default is 1s , optional configuration. This is a continuous detection period, used to detect the number of ARP packets in this time period . The default is 1S , so that is, within 1S , if 15 (default) ARP is exceeded , the violation is. This time can be selected from 1-15S. On R1 , ip route 1.0.0.0 255.0.0.0 null 0 then ip defaut-network 1.0.0.0 , then R2R3 will learn the default route Vlan 10 The next hop of 1.1.1.0/24 , because the AD value of OSPF is better than RIP . V1 defaults to send v1 to receive v1, v2 The preferred principle is IGP > EGP > Incomplete basic configuration Summarized as follows: About the configuration of PVLAN : / / Mark the routing table 192.168.1.0 as the default network Send TCP packet Ip helper-address 192.168.100.1 Turn on switch interfaces Port-Security will consume resources, Port-Security detects an incoming interface to each data frame to determine whether the flow method, or if there offenses. When a security interface settings violation to shutdown when the interface is in violation Therefore, BGP automatically summarize ( Auto-the Summary ) Summary Only redistributed redistributed routes, and the use of network command routing incoming class declaration ways. Currently CISCO IOS turns off automatic summarization by default. Protocol vulnerability Ip route 1.1.1.0 255.255.255.0 serial 0/0 STP port status Redirect time 600 sec, forwarder time-out 14400 sec Preemption disabled 1 Optimum and Distributed Switching But what if the A route is an OSPF external route? ^$ None uses the distribution list or the access control list deny 521 port. R1 RIPv1 If you reconfigure a secure trunk as an access port, port security converts all sticky and static addresses learned on the native VLAN to addresses learned on the access VLAN of the access port. Port security removes all addresses learned on VLANs other than the native VLAN. FIG fancy, initial condition, C interface is elected non-designated port is Block , B sent from the designated port BPDU to C . Let us first consider the case of 802.1D . When the link between Root and B fails, since the interface connected to B on C is BLOCK , it does not send BPDU to B. Therefore, B considers itself to be Root at this moment , so it goes to C. Send yourself a BPDU for Root . Because at this time , the interface of C also stores the BPDU sent by B to the previous B , and this BPDU is compared with the BPDU sent by B to B.It is better, so C ignores these suboptimal BPDUs directly . Until the Max-Age timeout, the BPDUs sent by the previous B stored on the interface of C will be aged. At this time, the interface enters LST and starts to send BPDUs , indicating that the root is Root. . At this point, B accepts the facts and sets the interface that connects itself to C as the root port.
