Port Vlans allowed and active in management domain Fa0/20 1,10,20,30 100 Then first mark the route prefix of 30.30.30.0/24 on R2 , use the community tag, and configure a route-map at the same time. Switchport port-security maximum 1 When a spanning tree constructs a loop-free topology, it always uses the same four steps to determine: Set metric-type internal SW1#show ip dhcp snooping binding (Of course, in the case of FA=0.0.0.0 ), then, in this figure, if the cost of R2 to ASBR-R3 is smaller, the final R2 will be preferred. First select root , the SW1 with the smallest MAC address of the switch wins and becomes root.

When no BPDU is received for a period of time and the lifetime reaches MAX age , the bridge considers that the port is connected. R5#show ip bgp 11.11.11.0 Configuration example Assigning community 100:11 to route 11.11.11.0/24 on R1 and passing it to R2 , then R1 is configured as follows: Different OSPF between two-point two-way process re-release, can also use a static summary route re-issued, respectively, in two ASBR create different static routes summary above, re-publish static summary routes in the corresponding processes. Management VLAN in a Layer 3 switch environment Network 100.0.1.0 mask 255.255.255.0 Inside the AS , the AS-PATH does not change, and the AS_PATH anti-ring cannot be used , so loops are easy to occur. * i Complete basic IP , IGP configuration, establish BGP connection A match to a start, the end of any single character string, such as A0 , a!

The local interface is used to establish a neighbor relationship with the peer directly connected interface. 200 ? Two modes of operation: normal (the default) and aggressive Between R1 and R2 , the original R3 and R4 are updated through a multi-access network, and BGP is run . Because of this self-learning and two R1 of BGP routes NEXT_HOP property 10.1.13.1 are directly connected,ccnp tshoot test, is reachable, Origin attribute (priority: IGP > EGP > Incomplete ) Community Ip community-list 11 permit no-export route-map test permit 10 BPDUFilter In Ethernet, multiple protocols can coexist simultaneously in a local area network. Therefore, setting the corresponding hexadecimal value in the Type field of Ethernet II provides a mechanism to support multi-protocol transmission in the LAN. description Sw(config-if)#switchport mode private-vlan host Mode ?

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.
