[Experiment 2 ] Neighbor + Route-map achieves the same function R1(config-router)#distribute-list 1 in ? // All interfaces Neighbor 5.5.5.5 update-source Loopback0 Bgp connected eigrp Use a hold-down timer to prevent routing loops Detailed rules 100 ( Well-known ) 3.3.3.3 802.1Q support 4096 Ge VLAN ! ! 4 R2#sh ip b 100.100.100.0 Therefore, when the deployment is re-released, this problem needs special attention. As for how to avoid the problem, I will introduce it in the following content. 200 i Verify the role of the match interface 2 AFI ( Address If R1 turns off auto-summary and network 1.1.1.0 mask 255.255.255.0 , then R2 can learn BGP route 1.1.1.0/24 5.5.5.5 1 : Request message, requesting all or part of the routing information from the neighbor; R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router rip //The default community is not sent,ccnp route unisa, so this command must be configured Which exchange method will be used Exactly the same, except that the list of AS numbers belong to the local Federation AS Display has not been loaded into the RIB in the BGP routing, and why not loaded Known via "ospf 1", distance 110, metric 20 Routing table Network 192.168.20.0 0.0.0.255 area 1 R8 to re-advertise 8.8.8.0 into the BGP , has spread to R10 , the R10 on the route AS_PATH is 98? , Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. Neighbor 3.3.3.3 update-source Loopback0 neighbor 5.5.5.5 remote-as 345 SW2 is the core layer switch, deploying DHCP relay Routing? The key point is that R2 , through the R2 deployment redistributed routing , routing information may be selected in different transmission routes between the domains. Interface vlan 20 Link aggregation mode Router(config-router)# passive-interface int- type int-num Advanced Features LP takes the maximum value of LP in the detailed routing No passive-interface fast 0/24 Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two BVI Bridge-Group Virtual Interface *> 11.11.11.0/24 Lowest sender bridge ID Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: Configuration view and verification 192.168.255.0/24 . End of a string port-security does not support etherchannel the port-channel interfaces MAC address Timer Ip dhcp relay information trusted A static route to the host Milne is added to the ROO . The next hop is the E1 port of Kanga . The purpose is to pass the bridge that is often congested. But found that Kanga will be sent to the host Ip rip trigger DAI supports on the access interface , trunk interface , EtherChannel interface , and private VLAN interface. Fa0/20 Lead ( PreambIe ) Origin IGP, metric 0, localpref 100, valid, external, multipath Switchport port-security maximum 1 Interface loopback0 *Mar 16 17:09:21.858: DHCPD: inconsistent relay information. 100.1.1.0/24 . At the same time, this re-release becomes the summary route of OSPF . Even if two ASBRs are returned , because there is a static summary route locally, the summary route of OSPF is directly ignored , and sub-optimal is not generated. Path, this route will not be re-released back to RIP and cause other problems. Mapping is only valid locally R1(config-router)#distribute-list 1 in ? // All interfaces Switch(config-if)# switchport access vlan 10 Configuration Example version B is RR , C and D are clients , BCD constitutes a route reflection cluster; a BGP route is advertised from C. R3 configuration is as follows When we set the number of MAC addresses allowed on the interface to 1 and set a secure address for the interface, then this interface will only be for that MAC. Reviser The MAC sublayer is physically layer-dependent, that is, different physical layers have different MAC sublayers for access. In Ethernet, there are two main types of MAC : 12(_34)?_56 Flooding the MAC table to the above port The non- root bridge receives the TCN on its designated port LocPrf Which exchange method will be used * Available routes (next-hop reachable ) Manually configure a secure address on the port-security interface. From the message we can see that the size of this IP packet is 1500 bytes. 200 i Hostname R3 interface s0/0 Must be a zero field. For experiments on specific Layer 3 switch management VLANs , see the CCNA Lab Manual By passhot. The route weight generated by the local network is 32768. But it must mention , this model because also store the relevant information , Statistically , approximately 65536 data streams (Flow) will consume 4MB of system buffer. Enables multiple gateways to be used at the same time and automatically detects active gateways. Access-list 2 permit 192.168.2.0 0.0.0.255 route-map PBR permit 10 200 i [ ] AS_CONFED_SEQUENCE A list of ordered AS numbers on a path to a particular destination. 100 i The route for no-export cannot be more or less. Path We found R4 on the R3 passed over 100.0.1.0 this route, AS_PATH to 100 100 , from R5 over is 200 , apparent from R5 to the routing AS_PATH shorter, it is preferred by R5 to R2 route. Network Origin IGP, localpref 100, valid, external, best Community: 100:11 no-export R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . *>i Typical configuration example: As shown in the figure, R1 and R2 open the LOOPBACK interface with the addresses 1.1.1.1 and 2.2.2.2/24 respectively . Heavy FAQ published Sw(config-if)#switchport mode private-vlan host * >i11.11.11.0/24 Active: capita ask if the other side can/will Method two: neighbor xxx default-originate Configure the Port-Security penalty mechanism COMMUNITY ? This is a very typical scenario. GS_SW is an aggregation layer switch that runs OSPF with the core switch . The GS_SW needs to advertise the network segment corresponding to the VLAN to be hanged , so that the core switch can learn the relevant routes. Then, once GS_SW announces the network segment corresponding to these VLANs in the OSPF process , the corresponding SVI interface will flood the OSPF HELLO message to the VLAN , and these messages are actually redundant.
