Router(config)#router rip RIP Message Format RFC1723 / / Modify the default parameters Port ID description Origin IGP, metric 0, localpref 100, valid, internal Configuration command 46 IP RSTP is able to quickly transition between edge ports and point2piont links. The link type of the RSTP is automatically obtained through the duplex state of the interface. If the interface is half-duplex, the link type is the shared port . If it is full-duplex, it is point2point . Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle . This will bring some hidden dangers to the loop. Therefore,ccnp switch tut, the route reflector needs to use the following two attributes to prevent loops: 200 i If you try to activate 8021.X on a port-security interface, you will get an error and the 802.1X function will not open. The configuration of R3 is as follows: SW1(config-if)# glbp 1 load-balancing host-dependent !! The same PC (source MAC ) is assigned to a fixed gateway virtual MAC Sw1(config-if-range)#switchport trunk encapsulation dot1q Configuration case !! On R1 , Fa0/20 port trimmed only vlan 1 and 10 , because this Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 Switch(config-if)# switchport trunk native vlan ? Route-map LP permit 20 match ip address pref 2 set local-preference 200 Topology change mechanism (detection) The cost of the route. ... Redis ospf 1 route-map test 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.
