May be provided for routing cost , cost-ID is equal to the time, preferably cost small. If the cost is equal, select the cost-ID is small. If an interface is in the flooding state,ccnp 300-101 topics, it will bring a lot of upadate and witdhdrawn messages to the network . Therefore, for a flipped interface, no bgp fast-external-fallover is recommended . After the interface is shut down, the BGP session and neighbor relationship will remain until Packets ? RIP re-advertises routes to OSPF : 1) Clear the MAC entries learned from all interfaces except the one that received the TC BPDU . Although this action may cause a brief burst of flooding in the network, it is also beneficial to refresh the CAM table and clear the stale entries. Sw(config-vlan)#private-vlan community In the past, switching was hardware-based forwarding, and routing was software-based forwarding, so the campus network used more switching networks. Vlans allowed and active in management domain Start a TC while timer for the root port and all non-edge designated ports . The timer value is equal to 2 times the hello-time timer. ! Ip helper-address 192.168.100.1 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, 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.
