* i Situation 3 14 packets, 7640 bytes DoS attack. Then it is recommended to limit the ARP message threshold on the interface . Support PVST Cc01.043c.0000 (10.1.1.252) Set ip next-hop verify-availability 10.2.2.2 20 track 2 Bgp default local-preference 500 // Modify the default LP value Knowledge point OSPF and EIGRP re-release R4 on the show ip bgp 172.16.0.0 If DHCP snooping is turned off or this is a DHCP- free network environment, such as a pure static IP address environment, use ARP R1 and R2 run OSPF , and announce the direct connection network and their respective LOOPBACK interfaces. R1 LO1 is 1.1.1.1 and R2 LO1 is 2.2.2.2. The TCN BPDU contains three fields, which are identical to the first three fields except the type field of the configuration BPDU . 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. Example 2 : DAI relies on DHCP snooping technology. In a network environment where users dynamically obtain IP addresses, we deploy DHCP. First, in order to avoid the suboptimal path problem, we use the distribution list in the in direction on R2 and R3 to filter out 1.1.1.0 . CISCO Note: If the DHCP relay agent is enabled but DHCP snooping is disabled, the DHCP option-82 data insertion feature is not supported. If the route learns to an EBGP neighbor,ccnp switch videos, it is reflected to all client and non- client IBGP neighbors. If the route to learn a client , it is reflected to all non- client an IBGP neighbors, and in addition to the client all except client The next-hop attribute can be changed by next-hop-self Remove VLANs from the current list RIP version number: CASE2 : BPDU sending bridge ID / / Is to shield the route from the RIP re-released in addition to 1.1.1.0 , and re-release the local direct connection Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). Configuration and implementation By default, the RIP running on the CISCO router sends v1 and receives v1 v2 . If the display is declared as v1 ( use the version in the RIP process) If the penalty value exceeds the pre-set threshold - the suppression limit: the penalty value reaches this threshold, the route is suppressed, ie not released, until the N half-life, the penalty value is reduced to another threshold: re-use threshold (de-suppression threshold) ), the suppression of the route is lifted. DAI configuration command Neighbor 4.4.4.4 update-source loopback 0 // Specify the update source as loopback0 The configuration of R2 is as follows: 3.3.3.3 If the BGP route is learned from other BGP peers , the MED does not carry the MED when it is advertised to the EBGP peer . This way the routing table: It can only be mapped to the ethernet of vlan Finally , select a designated port DP on each segment , sw1 is the root bridge, all interfaces are DP , and finally compare the two interfaces of the direct link between SW2 and SW3 . SW2 receives from the interface SW3 sent BPDU , SW3 also receive SW2 sent BPDU each compare your received BPDU in the bridge ID (also called the comparison transmission bridge ID ), the final SW2 since the MAC address Smaller wins.
