R4 knows that to go to the destination, it needs to go to AS100 via AS300 to get the purpose. Route redistribution Distribute-list 1 out ? 100.0.1.0 the BGP route, preferably up to R5 . Access switch configuration: Neighbor 10.1.23.3 remote-as 13 No synchronization no auto-summary Unreliable based on broadcast Ip arp inspection vlan {vlan_ID | vlan_range} LocPrf Ip route 1.1.1.0 255.255.255.0 serial 0/0 The EBGP neighbor learns 2.2.2.0 . The RIP management distance is 120 and the EBGP is 20. Therefore, EBGP routes are preferred . How to make R1 preferred RIP The smaller the RID of a BGP neighbor is, the higher the priority is. 10.1.12.1 from 10.1.12.1 (1.1.1.1) The BGP router appends its AS number to the AS_PATH only when the update message is sent to another AS ( EBGP peer ) . This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router, and the policy of modifying the AS_PATH for the IBGP neighbor is invalid. SwitchA hangs or Match ip address 1 SW1#sh int trunk Distance 100 192.168.12.1 0.0.0.0 1 Vlan 101 Enabling BPDU filtering on an interface is the same as disabling spanning tree on it and can result in spanning-tree loops. The configuration of R1 is as follows: Vlan 100 Not advertised to any peer Local If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . Local network and re-routed routes, LP defaults to 100 , and can be transmitted to other IBGP neighbors within the AS . The LP is unchanged unless the policy is deployed during transmission. Set metric 1111 Rule validation ( AS_SET type AS_PATH , i.e. {} in the AS number in AS_PATH when calculated as a hop) R1(config-router)# network 192.168.12.1 0.0.0.0 area 0 R1(config-router)# distribute-list 1 out At this time , the policy is used for R4 on R1 , and the route AS_PATH of 10.0 is inserted into the AS number of 100 100 , and R5 is preferably R3 . Why on R5 will select R3 , through experimental results, where R5 received two routes, one from the Federal EBGP neighbors, one from EBGP neighbors, the final preferred EBGP routing neighbors. 8 Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle . This will bring some hidden dangers to the loop. Therefore, the route reflector needs to use the following two attributes to prevent loops: 8.3.4 Questions 104 The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes. Both SW1 and SW2 can learn, and three-year-olds can do it. : ccnp O IA C 100 Bgp bestpath as-path ignore * 11.11.11.0/24 0.0.0.0 After this time has elapsed, the route entry will become 16 hops, marking the unreachable route possibly down .

It can be understood as a weight value. The larger the priority, the higher.

It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes. Case: Double Exit NAT Match ip address 1 Solution: The way to redistribute static summary route to avoid the sub-optimal routing and other issues //The details are not released. RootGuard ? ? In the above figure, R1 and R3 will update routes 1.1.1.0 and 11.11.11.0 to R2 . Of course, by default, R2 is definitely the preferred EIGRP. 802.1 D Try to establish a TCP connection Ip prefix-list 11 permit 11.11.11.0/24 route-map test permit 10 Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) Interface mode, configure the interface as DAI trusted , the default is untrusted Neighbor V AS MsgRcvd As mentioned above, a route is allowed to carry multiple community values ​​to form a community list. If you want to delete one or several community values, for example, Redistribute connected subnets redistribute rip metric 10 subnets network 192.168.23.0 0.0.0.255 area 0 Another recommended solution is to adjust the management distance of the routing protocol: Prefix-list ? Max age ? Router bgp 200 Ip as-path access-list 1 deny _600$ BGP decision Public Toxicity reversal Configured MAC Addresses : 0 !! Manually configured secure MAC address, not here RIP database 30 ? You can use route-map in the following BGP commands. By default, only the MED values of BGP routes from the same neighbor AS are compared , that is, if the two routes of the same destination are from different ASs , the MED value comparison is not performed . MED only affects the traffic between directly connected autonomous systems, and does not pass through the AS . The smaller the MED, the higher the priority. BGP is designed to AS transfer routes between, so it is actually a hop AS . Default route Fast switching may be called route-cache switching on some data.

Router ospf 100 In the list, the first AS number (that is , the one that goes to the destination closest to the AS ) 10.1.12.2 When 10.1.1.2 is reachable, the track object is true Protocol Interface BGP Speaker from IBGP routes learned whether it's advertised to EBGPpeer depends IGP and BGP synchronization to decide Other applications of regular expressions in CISCO IOS Reduce network migration time without disconnecting existing connections, and do not need to change device BGP configuration in large batches 13 At this time, on R4 , only 1.1.1.0/24 and 192.168.13.0/24 can be learned. // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 The problem that the static route associated with the outgoing interface is re-released. . Redundant RR environment Y Interface fast0/0 R2(config)# router ospf 1 The basic configuration is as follows: The configuration of R3 is as follows: Router(config-router)# distance eigrp internal-distance external-distance The role of the root bridge is preemptible Timer The IGP protocol, such as OSPF , declares a direct interface (the associated network segment). On the one hand, the network number corresponding to the interface will be imported into the OSPF routing process. On the other hand, the interface will activate OSPF and start.
