ccnp switch lacp with stp sim

For different routing protocols, the corresponding AD values ​​are shown in the table below. This is a well-known convention: The optional parameter length is used to indicate the length of the optional parameter field Catos port switch ID in the default priority 32 (priority . 6 th 'bit ) , the IOS switch default 128 (priority field . 8 bits) Route tag 1111 ( 20s time), start to enter the listening state Produced when the network topology changes. PC2 is a new host access, arranged 192.168.0.1 address, the address after the completion of the configuration, PC2 transmits to the network a Gratuitous ARP , to prevent someone within the network using the same IP address, the Gratuitous ARP is senderIP and target IP All are themselves, senderMAC is its own MAC . The possible values ​​for the first column are as follows: About PBR 80 Let's take a look at the role of these well-known values ​​of community : Establish BGP neighbors The prefix list contains the serial number, matching from the smallest ---------- Ip route 172.16.1.32 255.255.255.224 192.168.23.3 MAC address. Multicast packets, one for each address that was learned on the interface. You can limit these bursts of multicast traffic by reducing the max-update-rate parameter (the default for this parameter is 150 packets per second). However, if you enter zero Station-learning frames are not generated,ccnp switch lacp with stp sim, so the spanning-tree topology converges more slowly after a loss of connectivity. Optional attribute The configuration of R3 is as follows: R1 and R2 establish EBGP . On R1 , the network announces 11 and 12 network segments. To filter out 12 network segments, do not let them pass to R2 . AS_CONFED_SEQUENCE A list of ordered AS numbers on a path to a particular destination. The configuration of R5 is as follows: Access-list 1 permit 1.1.1.0 No synchronization no auto-summary Note that after the DHCP snooping is enabled on the switch , the dhcp packets are snooped. Therefore, when the DHCP attack is generated on the network, the performance of the switch will be seriously degraded. Therefore, you can limit the number of interfaces that can be received on the interface. Number of DHCP packets. Configure the number of DHCP packets per second that an interface can receive. The range is 1 to 2048.
