ccnp switch port security

Straight connector OSPF routes take effect, and only 1.1.1.0 routes survive. The source of continuous routing is direct routing,ccnp switch port security, or RIP . Then, if an OSPF process (this sentence may not be rigorous, everyone understands what I mean), the route can not be summarized, such as the following figure. Vlan 10 Community: inherits the community of all detailed routes , forming a list The configuration of R4 is as follows: 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 OSPF and IBGP route re-release Local origin Fa0/22 1,10,20,30 To verify which outbound interface is used for a particular traffic in destination-based load balancing, use FastEthernet0/0 IP protocol number 89 Version Network 192.168.10.0 0.0.0.255 area 1 We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows switchport trunk encapsulation dot1q switchport mode trunk CFI SwitchB first detects the topology change, and then generates the TCN BPDU and sends it out from the root port (because the root port is in the direction of the root bridge), B will continuously send the TCN BPDU until the designated switch C sends a TCN ACK to confirm. Network 5.5.5.5 0.0.0.0 area 0 15 Weight Ip nat inside source route-map nat4 interface serial0/0 overload 10.0.0.0/24 is subnetted, 1 subnets Portfast 100 No shutdown exit CAM table 100 Switch(config-if)# switchport protected After the Uplinkfast feature is activated , the switch automatically adjusts some parameters: When the number of prefixes received from the neighbor exceeds the maximum number 300 of 90% (default 75% ), generating a message log Ethernet data link layer basic configuration RIPv1 LocPrf Access-list 1 deny 192.168.13.0 access-list 1 permit any Route summary 23 Discard the illegal ARP packet, the switch will discard the illegal ARP after log If there is no tag , mark the PVID of the Access port and proceed to the next step. After bgp confederation iden 345 configuration, for the federated AS , this AS is not what 64512 , but 345 Ipv6 does not support Route-map cisco permit 20 match ip address 2 set metric 20 PAgP mode: Not advertised to any peer R2 configuration is as follows To confirm, the bridge responsible for notifying the topology change will continue to send TCN BPDUs before the bridge confirms the TCN . Next, the designated bridge will generate another TCN for its own root port , and the process is sent all the way to root . Limit the number of access hosts per port (number of MAC addresses) Bgp bestpath as-path ignore Interface: Interface for forwarding packets. Gateway of last resort is 172.16.12.1 to network 192.168.1.0 Ip helper-address command can configure the first to receive client broadcasts emanating discovery on the interface that three packets, after the broadcast DHCP messages will be relayed to unicast packets, is to take the IP routing It is. Therefore, in fact, the ORF is a feature of the route-filtering by means of the prefix-list . The prefix-list is pushed locally to the peer to allow the peer to perform routing prefix filtering. 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. For dynamic address allocation The current status of the Port Status : Secure-up !! interface is up . or: Double-point bidirectional routing re-issuing problems 92 5.5.5.5 Manually configure a secure address on the port-security interface. When there are multiple paths, the BGP Router only selects the optimal route ( BEST ) to use (without load balancing) Network 10.1.34.0 0.0.0.255 area 0 Router ospf 1 We know that there are several ways to form a secure address entry, one of which is manually configured using the switchport port-security mac , but this method is time consuming and laborious, and it is necessary to copy the MAC on the PC , and the work cost is relatively high. . Another way to form a secure address is to have the switch use dynamically learned MACs . However, these secure addresses will be lost once the interface is up/down , let alone rebooting the device. Therefore, you can use the sticky mac . After this method is activated, the switch will “stick” the dynamically learned MAC . The specific action is very simple. After dynamically learning the MAC (for example, a 00b0.1111.
