Weight Ip prefix-list ABC seq 5 permit 172.0.0.0/8 le 24 Trunk configuration description LOCAL-PREFERENCE 200 basic configuration Router bgp 64512 no synchronization no auto-summary Two-point two-way routes redistributed problems Network 11.11.11.0 mask 255.255.255.0 R3 receives two routes, respectively carrying the community attribute as above. Now, we only want to delete the no-export attribute of the 11 route . Diameter refers to a diameter value, the default is 7 . This value is related to the STP timer. If the different diameter values ​​are configured, the switch will automatically adjust the hello and max age timers. This command is usually configured on the root , so that the timer value is passed to other switches through bpdu . Second layer bundling A valid entry in the database matches these ARP packets. Experimental verification Neighbor 1.1.1.1 weight 2000 sets the route sent by the neighbor to 2000 weight (local) The above command only re-advertises OSPF NSSA routes into BGP. 200 i TCP/IP volume one Feature Overview 50 Then the configuration on R3 : 10 FastEthernet0/1 AS number . 2B , but with the network development, . 2B is not enough, so now expanded to 4 Ge B router bgp? You can view (Note: only available in certain IOS supported under version) The 10.1.10.0/25 subnet cannot be updated because the subnet and the update source interface belong to the same main class network, but the masks are different. Maximum-paths 2 Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federation EBGP in federated EBGP and IBGP Match abd , abcd , abccd , abcccd, etc. [Experiment 3 ] Cancel detailed route suppression for a specific neighbor Exit This feature is quite unstable and is not recommended. Ip address 4.4.4.4 255.255.255.0 If a psec port is punctured into err-disable , you can use the following methods to restore the state of the interface: 200 i Type of data. Run the switchport port-security mac-address command to configure a static security address entry. About Ethernet OSPFpassive-interface neither sends nor receives routing updates, nor does it send HELLO packets. Ip dhcp pool BIND Route-map nat3 permit 10 match ip address 2 match interface serial0/1 To verify which outbound interface is used for a particular traffic in destination-based load balancing, use 3.3.3.3 Maximum inhibition time: 60 minutes ( four times the half-life ) * Since the physical layer and the data link layer of the Ethernet are related, a specific data link layer needs to be provided for different working modes of the physical layer. This brings some inconvenience to the design and application. ? Route-map test permit 20 router ospf 1 The configuration of R3 is as follows: R4 MED , choose 3 Route, and redistribute the route into its own OSPF process 2 , then R3 will learn this route from process 2 , assuming R3 learns this first By default, only O and O IA routes in OSPF are redistributed into BGP. For example, if you go to a destination and there may be multiple equal-cost paths, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. Distance 100 192.168.12.1 0.0.0.0 1 If R1 turns on auto-summary and network 1.1.1.0 mask 255.255.255.0 , it is still updated to R2 with details. 0.0.0.0 Remote-ID type Adjust the management distance of the routing protocol 54 Exit Gateway of last resort is 172.16.3.0 to network 172.16.0.0 Modify AS_PATH with route-map About the configuration of PVLAN : When a router is directly connected through a point-to-point link, only one neighbor exists on each interface. Origin IGP, metric 0, localpref 100, valid, external, best For example, in R3 viewed on R5 sent me 6.6.6.0 of this OSPF external routes, you can see the tag field is 600 (automatically inherit the AS_PATH ) And this time, R3 the OSPF redistributed into BGP , the default is not automatically restored AS_PATH attribute, so you need: Dynamic routing protocol port number or protocol number 7 DHCP static address binding * OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello. Exclude one or more addresses from the address pool (such as gateway IP, etc.) to avoid assignment to clients Origin codes: i - IGP, e - EGP, ? - incomplete ? 3.3.3.3 FastEthernet FastEthernet IEEE 802.3 Network 11.11.11.0 mask 255.255.255.0 100 Second,ccnp tshoot practice questions, rule 9 , 10 skips The metric is a value) In CEF , there are two main types of load balancing, based on messages and based on purpose. Note that at this time, the routing table is used to recursively find the route to 10.1.12.2 , so there must be reachable routes in the routing table. Two-point two-way routes redistributed problems Match ip address 1 router bgp 100 It is worth noting that we can manually modify the management distance of the routing protocol in the specific protocol process on R4 , so as to affect the routing of the router itself. For example, on R4 , we will default the administrative distance of OSPF to external routes. 110 , modified to 130 , greater than the RIP management distance of 120 , so that R4 in this environment, for 192.168.1.0 will optimize the RIP route, you can avoid the problem of sub-optimal path and routing feedback .
