BGP routing table entry for 100.0.1.0/24, version 3 The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text , the security address will not be lost even if the device is restarted. Hostname R3 interface s0/0 Sw1(config-if-range)#no switchport // Configure the L3 interface 2.2.2.2 Lease expiration Path On R1 ,ccnp tshoot 642-832 official certification guide, ip route 1.0.0.0 255.0.0.0 null 0 then ip defaut-network 1.0.0.0 , then R2R3 will learn the default route Decision making Interface vlan 10 / / Configure etherchannel , ID is 1 , the mode is desirable I can't ping because I found a subnet route after looking up the table at 172.16.1.1 . Therefore, the search is limited to the subnet route, and then the route is found to be mismatched. Therefore, the packet is discarded directly without going through the default route. . Packets For the contents of this section, please refer to the relevant chapters of the path properties of this document. Configuring a VTP domain name Switchport port-security mac-address sticky Example 3 of ip community-list (strictly matching community ): An entry stored in the log buffer can represent multiple packets. For example, the switch receives the same ARP from the same interface and the same VLAN. The spanning tree topology in the network is attached to the timer of the root bridge, and the root passes the timer in the BPDU to all switches on the second layer. Router(config)# router ospf 1 Hostname R5 Remove The figure above is the initial state. Working Mechanism 200 i Community Router(config) router rip – LoopGuard and RootGuard cannot be enabled at the same time The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first, then B routes will be injected into the OSPF , the finally R3 learned, then R3 , the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
