Due to the existence of the principle of horizontal splitting, BGP requires that the IBGP be fully interconnected within the AS (here, the neighbor command specifies). (The root cause is in Command Use the dynamically learned MAC address to form a secure address entry. (global configuration mode) ip dhcp relay information trust-all Dhcp-bindings all —Logs all packets that match DHCP bindings. Just match (65000) 2 : Reponse message, send all or part of its routing information, a Response Take the R5 . Then we can use the route-map in the OUT direction for R4 on R3 and R5 , and control the LP value. 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 It can still be saved after the up/down phenomenon occurs. After using wr , these sticky secure addresses will be written to start-up config and will not be lost even if the device is rebooted. Ip dhcp snooping trust Public Hostname R1 interface s0/0 The lower the value is set, the higher the protection level for the CPU . This value takes effect before and after the penalty action occurs. Of course, this value cannot be set too low. At least the legal traffic must be processed. Generally less than 1000 is almost the same. Configuration example 46 10.1.13.3 BGP decision Set metric-type sets the metric type of the target routing protocol It is allowed to write multiple next hop IPs , but these IPs must be the interface IP of the directly connected router . On R1 , default information originate is also formed, and R2 and R3 will learn the default route of 0/0 . This command is for RIP Aggregate-address summary address summary-only as-set aggregate-address 192.168.0.0 255.255.0.0 as-set after, R1 can only learn to 2.0 , the summary route are rejected,ccnp route lab manual pdf, the reason is 1.0 carries no-adver of Community Community , when the summary route plus the as-set keyword after Will inherit its community , so the summary route also carries no-adver , this time 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. switchport trunk encapsulation dot1q switchport mode trunk The DA 40bit multicast address is used to indicate that this FRAME is an ISL . CASE4 : ARP spoofing principle Match any single character, including spaces Errdisable recovery cause arp-inspection no ip dhcp snooping information option Router bgp 12 table-map PA TblVer InQ OutQ Up/Down State/PfxRcd For specific supported equipment, see the official CISCO documentation. Two modes of operation: normal (the default) and aggressive Vlan 10 Certification After completing the above steps, the logical etherchannel interface is set up. Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. None Etc., then there is a prioritization between these methods: network>redistribute>aggregate Note that this principle is not used as a BGP routing routing policy. I can't ping because I found a subnet route after looking up the table at 172.16.1.1 . Therefore, the search is limited to the subnet route, and then the route is found to be mismatched. Therefore, the packet is discarded directly without going through the default route. . VTP Version capable Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. BGP table version is 1, local router ID is 4.4.4.4 The protocol for RSTP BPDU is 2 and the version is 2 . Ip mtu ? refers to the three-layer MTU . This value can be manually modified, but the maximum value must be less than the interface's Layer 2 MTU value, which is 1500 . This MTU refers to the total size of the three-layer IP packet. If the packet sent by the interface is larger than the ip mtu of this interface , the IP packet will be fragmented. AS list, which is unordered and can also be used to prevent ringing. When the manual summary command using the as-set keyword is used , the path attribute of the summary route is already rich and complete because it inherits the attributes such as AS_PATH . Therefore, the atomic-aggregate attribute is not needed in this case. Look at the packet capture results below, there is an aggregator , but no atomic-agg .
