R2 re-advertises the A route, then according to the preemptive rule, R3 will ignore the R1 update about the A route. At the same time, due to the deployment of two-way re-release, R3 will further re-publish the learned A- route back to process 1 . The 802.1Q Tag contains 4 fields, which have the following meanings: First come to know the first three-layer interface: SVI switched virtual interface, a logical interface of SVI , that is to say not a physical interface, when we create a VLAN on the switch , we can create a The SVI interface corresponding to the VLAN , for example, we created Select the port for the Channel C 192.168.12.0/24 is directly connected, Serial0/0 1.0.0.0/24 is subnetted, 1 subnets The range is 10 - 1000000 If both are open We expect the effect of the above configuration is implemented R1 to 100.0.1.0 routing setting MED = 100 , 2.0 disposed MED = 200 is , while R2 to 100.0.2.0 disposed MED = 100 , 1.0 arranged MED to 100 , respectively, to the respective property The EBGP neighbor takes effect, so the MED attribute will be passed along the route in AS345 and finally arrive at R4 . Matches the preceding character 0 times or 1 occurrences Exactly the same, except that the list of AS numbers belong to the local Federation AS 0 100 0 100 i Router bgp 300 Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). This command can be used in the following ways: The maximum number of secure addresses, the upper limit allowed by different software platforms is different, but the default is 1 . Preferably , the routes sent by the EBGP neighbors (relative to the IBGP neighbors) are preferred to the EBGP routes in the EBGP and IBGP . Note that the first six rules in the BGP routing rules cannot be determined. Only in case of circumstances. After the configuration is complete,ccnp route sim, use clear ip bgp * soft to reset it softly. 10 FastEthernet0/1 ARP response packets can be sent directly without a request, which leaves a huge loophole for the attacker. <1-4294967295> community number The weight of the BGP route generated by the local summary is also 32768. R3 's loopback interface IP has been declared into OSPF , and R4 learns loopback routing through OSPF . Therefore, the BGP table for R4 is as follows: R2# sh ip ro 100.100.100.0 The LP attribute of the route is preserved throughout the federation Ip route 0.0.0.0 0.0.0.0 Education Network Next Hop IP 10 *>i 3.3.3.3 200 100 0 100 i Next Hop Switch(config-if)# spanning-tree [ vlan vlan-id ] port-priority pri The switch that first recognizes the topology change sends the TCN , the designated bridge receives the TCN and immediately returns a normal BPDU with the TCA set. Redistribute static subnets The R3 routing table is OSPF 's B segment route, then this B network route will be re-released back to the RIP domain, and ultimately to update The range of prefixes to match, ranging from length to le-value The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. Weight Re-advertise routes between different OSPF processes 1 15 Ip dhcp snooping limit rate rate 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 .
