After this time has elapsed, the route entry will become 16 hops, marking the unreachable route possibly down . Gateway of last resort is not set Passive-interface defualt The smaller the RID of a BGP neighbor is, the higher the priority is. Weighting 100 (default 100), thresholds: lower 1, upper 100 10.1.13.3 Whether the MAC correspondence is legal The range is 1-255 Network 10.1.34.0 0.0.0.255 area 0 200 i Each AS has an identification number ranging from 1 to 65535 ,9tut ccnp switch 300-115, of which 64512 to 65535 are reserved for private use. At this time, R1 is preferred . If you want R2 to be preferred R3 ? R2 is added as follows: Switch(config)# vlan 255 Switch(config)# interface fast0/1 EtherChannel [Experiment 5 ] There are subnet routes, the subnet route prefix length is different (but both match), and the longest match Loopback Loopback interface Router bgp 345 A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . After the above configuration is implemented, R1 will filter out the 3.0 route. There are 1.1.1.0 , 2.2.2.0 routes on R1 . Configuring a VTP domain name Virtual-Template Virtual Template interface Virtual-TokenRing Virtual TokenRing Show ip bgp injected-path to display 100 i port-security does not support etherchannel the port-channel interfaces 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . Technical overview 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.
