Total MAC Addresses 0 Router(config)# router eigrp 100 Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself The type parameter in the above command is used to indicate the hardware type of this hardware address. If type is 1 , the type is ethernet , if type By default, BGP does not allow static default routes to be injected when static is re-released ; unless it is in the BGP process at the same time default-information originate Route Tag Y Redistribute ospf 1 Neighbor 10.1.12.2 capability orf prefix-list receive Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. (interface) ip load-sharing per-destination R3#show ip bgp summary Abc+d EIGRP summary routing / / Match the commu value to be deleted Features Overview ...... Trunks can be statically configured or negotiated through DTP . Looking at the above picture, we made a manual route summary on R3 . This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost. AS_PATH attribute, then if R4 and R1 or 10.1.13.3 Route-map test permit 10 match interface Serial0/0 router ospf 1 3.3.3.3 Ip dhcp pool BIND Ip sla monitor responder SW3 immediately aging the BPDU stored on Fa0/3 , and port Fa0/3 enters the listening state and starts to send BPDUs. Transmit limit accumulator 0x0 (0x0) IP MTU 1500 Ip arp inspection trust Knowledge review Not advertised to any peer Local 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: Interface trust status and network security issues Sw(config)#vlan 201 Route-map test permit 10 * i100.0.1.0/24 The dst-mac detects the received destination ARP packet. The destination MAC address of the Ethernet frame header is the same as the target MAC address in the ARP body . This check is for ARP response . When this option is enabled , ARP packets are discarded if the two MAC addresses are inconsistent. Internal Fast Switching Port Content Addressable Memory Table content addressable memory RFC1724 After completing the configuration, R2 show ip route DAI - Dynamic ARP Inspection Revision statement LocPrf ------------- Length Ip route 1.1.1.0 255.255.255.0 serial 0/0 Neighbor 10.1.12.2 remote-as 200 After deploying DAI , we can define the trust status of the switch interface: trusted , or untrusted , for trusted ports, it will not be received. 100 i Router bgp 345 Switchport port-security maximum 1 Vlan 10 FastEthernet0/0 Switch(config)# spanning-tree portfast bpduguard default After the example triggers the penalty mechanism and enters the err-diasble state, this can effectively prevent the switch from being too high in CPU utilization due to handling of violation events . However protect and restict punitive measures will not shut down the port, the port is still available,ccnp switch how to master, then this may lead to in the case of offenses occurred switch CPU utilization soared high (for example, the influx of a large number of illegal data). Therefore, when using the two violations of protect and restrict , you can prevent the CPU from being high by the Port-Secuirty rate limiter .
