It can be flexibly set according to actual needs. After the above configuration is completed, R2 will be in the routing table. Lab topology and description Route is punished by dumpend OSPF redistributes into BGP Detailed rules Number of existing VLANs 8 Maximum inhibition time: 60 minutes ( four times the half-life ) Longest matching principle Understanding Port-Security DHCP server messages (such as DHCPOFFER, DHCPACK, DHCPNAK , or DHCPLEASEQUERY ) will be released. On the contrary, packets received from the DHCP server on the untrust interface will be filtered out, thus preventing illegal DHCPserver access. . While the deployment of DHCP Snooping the switch locally, but also to maintain a DHCPsnooping binding database ( the Binding Database ),ccnp r&s, save for listening to the DHCP entries interaction, information includes (for untrust interface): the MAC address, IP address ( assigned by DHCP ), lease, binding type, VLAN number, and interface number (the DHCP client is the untrust interface connected to the client PC ) . This oneIn addition to doing some basic security access control, DHCP snooping banding databse can also be used for anti- ARP spoofing solutions such as DAI .
