BGP routing rules 1 The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally,ccnp switch dumps june 2018, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. During the migration, the router running DUAL AS can establish EBGP with the external AS using both the primary AS and the secondary AS. Knowledge review Next Hop Mode Before the DAI is deployed , if the ARP spoofing behavior occurs on the intranet , for example, the PC sends an invalid ARP packet, the switch cannot detect and defend the defensive action. Path Switchport access vlan 10 interface fast0/24 If you reconfigure a secure trunk as an access port, port security converts all sticky and static addresses learned on the native VLAN to addresses learned on the access VLAN of the access port. Port security removes all addresses learned on VLANs other than the native VLAN.

For the above reasons, topology changes can occur at different times and in different network segments in the switched network. If the Layer 2 interface switches directly from the block state of the spanning tree to the forwarding state, a temporary data loop may occur. To alleviate this problem, the port should wait for new topology information to propagate to the entire switching network before starting to forward the data frame.
