If the route is marked d , it means that the route is suppressed. If it is h , it means that the route has signs of flipping. R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. If you reconfigure a secure trunk as an access port, port security converts all sticky and static addresses learned on the native VLAN to addresses learned on the access VLAN of the access port. Port security removes all addresses learned on VLANs other than the native VLAN. Process exchange R2# sh ip ro 100.100.100.0 You can learn these two external routes. Advertised to update-groups: 1 MST This environment is relatively simple, PC and DHCP server in the same VLAN , I mainly want to confirm that the ordinary switch pair is carried Recognized as a self-determination attribute. LP is the local priority and is used for Update messages between internal peers ( IBGP ) , but not to other EBGP neighbors. The larger the LP value, the higher the priority. R3 The configuration of R2 is as follows: 5.5.5.5 Interface fast0/1 Supplementary] When the same AS in the BGP router A introduces a route, A router transmitted the route to its IBGP neighbors B , has been If the router accepts the parameters of the neighbor in the OPEN message, it will answer a keeplive message, and send the message for the period of 1/3 of the holdtime (but not less than 1S ). CISCO defaults to 60S . If the hold time is 0 after negotiation , the keepalive keep-alive message is not sent . R3 sets the tag when injecting the route. * 11.11.11.0/24 0.0.0.0 Configuration case MED When ISP1 is down, and the interface of GW connected to ISP1 is DOWN , the data of PC accessing 100 network is switched to ISP2. Then, first R2's own routing table will change, 3.0 routing is filtered out, and R3 is the downstream RIP router, 3.0 can not learn. Marker : for detecting BGP loss of synchronization between peers, the message authentication, and in the case of supporting an authentication function if the message type is open or open message does not contain authentication message flag field is set to all 1 , The election of the root bridge will not be said. Next, look at the two interfaces of RP and SW2, and both will receive the BPDU , and the BPDU received by the interface connected to the root will be received . Neighbor 3.3.3.3 peer-group IBGP_peers neighbor 4.4.4.4 peer-group IBGP_peers Neighbor 3.3.3.3 remote-as 345 Network 11.11.11.0 mask 255.255.255.0 Ip prefix-list huizong permit 172.16.0.0/16 ip prefix-list mingxi permit 172.16.1.0/24 ip prefix-list xiayitiao permit 10.1.24.4/32 route-map RP_mingxi permit 10 TYPE indicates what type of frame this is, such as Ethernet, Token Ring, etc. Neighbor 4.4.4.4 update-source Loopback0 Dhcp-bindings all —Logs all packets that match DHCP bindings. When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Mtu 1500 , so it will be fragmented, then on R2 , the two fragments are reorganized. Dynamic routing protocol port number or protocol number 7 Path control 77 After receiving the BPDU sent by SW3, SW2 stops sending its own BPDU. 100 Ip address 10.1.12.2 255.255.255.0 Interface fast0/1 Neighbor V AS MsgRcvd AS345 in R3 ,ccnp tshoot download, R4 , R5 running the OSPF . The intra- AS uses IGP to ensure the interworking of internal routes to meet the internal data transmission requirements. It also provides the underlying routing support for IBGP connections. As a transport AS , Transit AS , running IGP can also ensure that BGP routes are in the AS . The delivery, while the validity of BGP routes ( such as the reachability of the NEXT_HOP attribute ) also requires IGP to make a basic guarantee. So, the first step is to complete the configuration of this IGP protocol.
