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. Switch(config-if)# switchport port-security aging time ? *>i100.0.2.0/24 If an OSPF in- process route cannot be summarized: BGP Deaggregation For the contents of this section, please refer to the relevant chapters of the path properties of this document. Each routing table entry must include at least the following three items: LocPrf Routing Protocols 5 In a real-world environment, an IP address is generally used to indicate the object of communication, and the function of ARP is to " resolve " the IP to the corresponding MAC address. So they will be put into the IP global routing table, labeled B . Due to the different port types, the switch processes the frames differently. The following is introduced according to different port types. 2 Four types of AS_PATH path attributes The switch sends data frames according to the discovered outbound interface. Configure Port Security Rate Limiter Each routing table entry must include at least the following three items: The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits are not concerned, and the mask must be /8 . Match ip address prefix-list 1 Virtual-PPP Virtual PPP interface In the route-map in the set community [ac 1-2]$ Local updater ID is 0.0.0.0 (no valid interface found) Flash: Database agent URL We found that both routes are best and are loaded into the routing table. BGP routing table entry for 172.16.0.0/16, version 3 / / View command: Show etherchannel 1 summary 100 s> 172.16.10.0/24 The first 8 bits of the route must be exactly matched with the first 8 bits of 172.0.0.0 . The other bits do not care, and the mask length must be greater than 24. Note that here Sw(config)#vlan 100 Some IOS does not support the neighbor R3 filter-list 1 weight command. * i100.0.2.0/24 Figure 2 R1 and R3 are the same AS , and the route of the 13 network segment is updated to R2 at the same time . The experimental effect is also in accordance with the rule description. If it is in the IBGP environment, that is, R1 , R2 , and R3 are all in one AS , then the rule Rules do not apply (empty), in other words, the MED will not be transmitted out of this AS Let's take a look at the role of these well-known values ​​of community : Through the original properties affect routing 16 Lowest sender bridge ID This feature uses the CDP table of the device to determine the reachability of the next hop. Experimental topology and description 1 ? Routing Information Protocol Start a TCP connection. Prepare enough resources when BGP is enabled Invalid timer Provides load balancing and redundancy Debug ip dhcp server {events | packets | linkage} Enables debugging on the DHCP server Milne 's packet was sent to Roo because he learned the wrong one. R5 performs link redundancy. However, at this moment, R5 can only go to the target network through R2 . Request message: You can request the entire routing table or request specific routing information. Load balancing AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS Bridge ID of the root bridge Neighbor 10.1.23.3 local-as 201 no-prepend replace-as Path ? Define the network segment associated with the address pool Neighbor 5.5.5.5 weight 100 By AS_PATH influence route selection SW1 (config-if) # glbp 1 priority 120 No synchronization no auto-summary A very simple method, assuming R3 on the R3 , the first RIP to OSPF route re-release, as already mentioned, a direct problem is on R2 , due to the 192.168.1.0/24 route, and from OSPF and RIP learned, and OSPF the AD value is small, thereby resulting in sub-optimal path, so in order to circumvent this problem,ccnp route vrf, we can directly in R2 deployment on the distribution list, so that the OSPF routing is not loaded into the routing table, in order to avoid suboptimal Path problem.
