Next is the re-release of EIGRP to OSPF : Passive-interface When the network topology changes, the switch that first recognizes the change will send a TCN BPDU . The switch sends a TCN when the following times occur : 100 1 ...... Switch(config)# vlan 10 Router(config-router)# passive-interface default Router(config-router)# no passive-interface int- type int-num Set metric-type internal Configure the DAI to occupy the size of the log buffer (the maximum number of entries), the interval is 0-1024 These MAC addresses as VLAN bridge spanning tree ID in the MAC address portion. Different switch models support different available MACs 5.5.5.5 Neighbor R3 filter-list 2 weight 5000 This fulfills the demand. 86025 We use ip ospf cost 100 on the F0/0 port of R4 to increase the interface cost , so the result is as follows: ? It is usually a direct connection because it will look for direct routes. EBGP default TTL is 1 Weight After Port-Security is enabled, related parameters have default configuration. SW3 receives this BPDU , but finds that this BPDU is less preferred than its own locally stored BPDU , so the BPDU is ignored. A route-map defined on the interface . In this way, only the PBR action will be performed on the traffic entering the interface . The traffic originating from this device is invalid. OSPF redistributes into BGP Through the above configuration, the BGP neighbor relationship can be established, let's show it: If R1 turns on auto-summary and network 1.0.0.0 mask 255.0.0.0 , it is advertised to R2 summary route 1.0.0.0/8 Network 100.0.1.0 mask 255.255.255.0 Sw1(config-if-range)#switchport mode trunk 16 If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. Gratuitous ARP Neighbor maximum-prefix xx The default is shutdown , optional protect , restrict 1) Clear the MAC entries learned from all interfaces except the one that received the TC BPDU . Although this action may cause a brief burst of flooding in the network, it is also beneficial to refresh the CAM table and clear the stale entries. Version 8bit , V4 currently uses more versions Bgp inject-map map1 exist-map map2 [copy attributes] ICMP redirect 8 IP nodes can communicate, and communication is actually the process of data interaction. Data interaction requires network devices to help us transfer data between two communication nodes. When the router (or other Layer 3 device) receives an IP packet, the router will find out the purpose of the IP packet in the Layer 3 header. Establish IBGP full interconnection and close the synchronization mechanism. This method is basically used at present. But this method has a flaw, that is, if IBGP Local origin The Permit/deny keyword has a different role in different deployment scenarios. Initially, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 , then we can configure it on R2 as follows: R2#sh ip route Second, rule 9 , 10 skips Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . Acl-match none —Does not log packets that match ACLs. At the same time, if 172.16.1.0 and 172.16.2.0 are all DOWNed at this time , the summary route also disappears. Neighbor 1.1.1.1 remote-as 123 Router ospf 100 / / Set the interface mode to Trunk mode * i100.0.1.0/24 The smaller the RID of a BGP neighbor is, the higher the priority is. !! The red font part is the number of hops to be increased 5.5.5.5 External BGP The BGP update package is as follows. You can note that the length of the AS is 2 , which is " 300 , 100 ". Note that this is an ordered list of ASs . None You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface . match. As long as the community contains 100:11 or no-export Distribute-list 1 out The physical interfaces belonging to a port-channel must have the same configuration as below. The configuration of R1 is as follows: To verify which outbound interface is used for a particular traffic in destination-based load balancing, use This fulfills the demand. WORD SW1 (config-if) # glbp 1 priority 120 !! Priority defaults 100 ,ccnp rs, the highest priority becomes the AVG , under equal priority, the maximum IP interface becomes the AVG . Default " AVG preemption" is off Next Hop *>i100.0.2.0/24 When the switch receives the configuration BPDU from the Root that the TC flag is set , they use the forwarding delay timer (default 15S ) to update the entries in its MAC address table. In other words, the lifetime of the entry is changed from the default value of the original 300S to 15S , which ensures that the MAC address entry is refreshed more quickly. The switch will continue this process until it no longer receives a TC BPDU message from the Root .
