Vlans in spanning tree forwarding state and not pruned The direct result of this command is that the metric of 192.168.12.0 in R3's original routing table is 30720 , but now it is 10000 , which becomes 40720 . We see that after the offset command is configured , what actually changes is the DLY that is updated to the neighbor . Because it is true that DLY is the best, the default Shows all routes received from the specified neighbor (a subset of the previous command, shown here is the route remaining after the inbound policy is executed) In the cmd of windows PC , the packet size after ping is the size of ICMP data , ping –l 1472 ,ccnp 300-115 tut, and the generated packet is 1500 bytes. ? !! vlan10 activates DHCP snooping 1,20,30 Neighbor 1.1.1.1 update-source Loopback0 Communicates with all other ports description Netflow switching In the route-map in the set community Interface vlan 10 Note also that, because the R4 and R5 for the federal EBGP neighbor relationship, so there are also TTL is 1 problems, if they use the loopback interface to establish BGP relationship, it needs to use to neighbor 5.5.5.5 ebgp-multihop 3 command. Sw1(config)#interface range fastEthernet 0/1 – 2 // Enter interface range Sw1(config-if-range)#switchport // Configure the interface as a Layer 2 interface Port 10.1.12.2 Port Note that the neighbor 1.1.1.1 filter-list x weight yyy command can be used multiple times for a neighbor, that is, set different weights for different routes . But the neighbor 1.1.1.1 filter-list 1 command, in the same neighbor in or out direction, can only be used once, these two commands are very different 1,20,30 Bgp bestpath as−path ignore This command, if configured, skips this rule BGP table on R4 : 100 Experiment 1 All clients in the route reflection cluster should establish IBGP connections with and only with all RRs in the cluster. Neighbor 1.1.23.2 send-community No off default route above configuration, adding a destined 13.0 network routing next hop is R3 , the PC to 13.0 data network switch to R3 proof ip default next-hop priority routing detail below, above Default route. The ip community-list is also like ACL . There are standard and extension points, 1-99 is the standard, and 100-199 is the extension. Extended community-list All VLANs Router bgp 345 Use as-path access-list to match routes BGP table on R7 : Experiment 1: host-dependent Maximum-paths ibgp 2 , then on R4 , in the ip routing table, there will be load balancing of BGP routes, but note that R4 is Fa0/22 1-4094 It can only be mapped to the ethernet of vlan Select the route with the smallest neighbor IP address ( the address of the neighbor in the neighbor configuration of BGP , that is, the update source IP of the neighbor ) Situation 3 ? As shown above, the R1 deployment, R1 use heavy publishing directly connected with the introduction of the three external routes, then out distribution lists direction only doing what A non-reflector router can participate in IBGP full interconnection or as a reflector client. Based on packet load balancing, all packets are rounded on the outgoing link. If you want to use message-based CEF load balancing, you need to configure this command on all outbound interfaces. The buddy experiment has verified that it can indeed be per-packet load balancing. Ip route 172.16.1.0 255.255.255.224 192.168.12.1 The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as: R4#sh ip b However, at this time, R3 will also receive the summary route from R2 release, which may form a routing loop, so it needs to be filtered out. Add configuration on the BGP process on R2 : C 192.168.12.0/24 is directly connected, Serial0/0 1.0.0.0/24 is subnetted, 1 subnets Router ospf 100 On a specific interface, if no BPDUs are received for three consecutive cycles (or max-age timeout), the STP data on the interface will age rapidly. As a result, the BPDUs are somewhat similar to the keep-alive mechanism between switches . This fast aging mechanism helps to respond quickly to topology changes. R3 is passed to other BGP neighbors. However, this summary route loses all the attributes of the underlying detailed route. Among them, AS_PATH is the most critical, because once the AS_PATH attribute of the detailed route is lost , this summary route is very likely to generate a routing ring. road. Therefore, it is necessary to let R3 warn the downstream BGP peers , tell them that 1 , this is a summary route, 2 , where the summary route occurs, that is, the originating AS and the originating router of the summary route .
