Option packet structure: Block all ARP requests or on the DAI untrust interface (note the separation from DHCP snooping 's untrust interface) The Control field is composed. Summary 1) 2) two points is MED in IBGP passed without problems (not lost) between, but EBGP between transfer depends on whether the route originated in themselves. In TCP/IP , the encapsulation format of Ethernet IP data packets is defined by RFC 894 , and the IP data packet encapsulation of IEEE 802.3 network is encapsulated by RFC. Configuration command 65 Completed in the logical interface 4 This attribute may not be supported. Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. Fast Switching Prefix-list RIP-2 Only PVST+ has been improved in this respect. PerVLAN means that a VLAN corresponds to a spanning tree. In this way, the switch will calculate the spanning tree based on the VLAN . We can adjust the priority and other related parameters by using a separate VLAN spanning tree, thus affecting Spanning tree calculations ultimately achieve reasonable link bandwidth utilization. For example,ccnp switch 642-813 pdf, in the above figure, there are two VLANs , 10 and 20 on the intranet . Let SW1 become the primary root of VLAN10 (the lowest priority of the whole network switch), SW2 becomes the secondary root of VLAN10 , and SW3 has the highest priority, so we will BLOCK off. SW3 is connected to the upper port of SW3 . In contrast, VLAN 20 is also the most specific adjustment. In this way, the user of VLAN 10 will go out to the left link, the user of VLAN 20 will go to the right, and the link is properly used to achieve load balancing.
