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 Decision summary Through the original properties affect routing 16 Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Local origin Aggregate-address summary address summary-only as-set Let's take a look at the role of these well-known values ​​of community : R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 , tag#11 , and the route is passed to R2 . On R2 , the redistribution of RIP to OSPF is deployed. After the external route of 3.3.3.3 is injected into OSPF , the tag value is carried by default. Metric problems 44 A policy-list is like a route-map that only contains a match statement. The Layer 2 switch searches for VLAN configuration information based on the destination MAC address and VLAN ID of the frame, and determines from which port the frame is sent out. Flooding the MAC table to the above port The destination IP address of the route , which can be the address of the natural network segment or the subnet address or Access-list 1 permit any route-map PBR permit 10 match ip address 1 The AS_PATH can be controlled by the policy to affect the route selection. For example, if you want R3 to reach the 1.1.1.0 network priority R1 , you can make a policy on R2 , as follows: In the above figure, there is a Layer 2 link between the customer and the carrier network. If the client's device is elected as the root bridge for some reason, it is troublesome. Therefore, the rootguard feature can be used to connect the client to the interface of the carrier. Deploy on. Then when these interfaces receive better from the customer AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS The configuration of R1 is as follows: 16/32 bit Private AS number A tool used to control routing updates can only filter routing information and cannot filter LSAs . Routing strategy needs (reliability, redundancy,ccnp switch 300-115 vce free, offloading model, etc.) Flex links and Port-Security are not compatible with each other Use 224.0.0.9 – LoopGuard and RootGuard cannot be enabled at the same time BGP table Includes 7 -byte preamble (a string of 1 , 0 intervals for signal synchronization) and a 1 -byte frame start delimiter ( 10101011 ) You can use loop guard to prevent alternate or root ports from becoming designated ports because of a failure that leads to a unidirectional link. This feature is most effective when it is enabled on the entire switched network. Loop guard prevents alternate and root ports from becoming Designated ports, and spanning tree does not send BPDUs on root or alternate ports. Network 100.0.2.0 mask 255.255.255.0 Neighbor R2 default-originate route-map test As mentioned above, the secure address entry formed by the dynamically learned MAC address of the interface will lose the secure address entries formed by the dynamically learned MAC after the interface is up/down , but all interfaces are used. The switchport port-security mac-address is manually configured and the workload is too large. Therefore, this sticky mac address allows us to turn these dynamically learned MACs into a "sticky state " . It can be simply understood that I will learn dynamically, and after I learn, I will glue you up to form a "static". "(Effectively SecureSticky ) entries.
