Ip prefix-list 1 permit 1.1.1.0/24 route-map test Ip prefix-list 1 permit 100.0.1.0/24 The above command creates a policy-list ; the Policy-list can only contain a match statement. In a real network environment, we may encounter a situation where there are two or more routing protocols in a network environment, for example: Redistribute rip subnets route-map test If both neighbor 1.1.1.1 weight and neighbor 1.1.1.1 filter-list 1 weight xxx are used , the latter is preferred 200 i If the route learns to an EBGP neighbor, it is reflected to all client and non- client IBGP neighbors. * i100.0.1.0/24 Passive: passively wait for other side to ask RIP-2 MD5 Authentication For example, in this example, we want to inject, the metrics of the two routes 192.168.1.0 and 192.168.2.0 become 2 hops, and 3.0 becomes *>i11.11.11.0/24 100 i 0 100 i Router bgp 100 At the same time, the same OSPF route is learned from both processes and is used on a first come, first served basis. Therefore, if R3 first learns the route from R1 , it will naturally ignore the one that R2 re-releases. However, if the neighbor relationship between R1 and R3 is already obtained in R3 FastEthernet1/0 Network R4 knows that to go to the destination, it needs to go to AS100 via AS300 to get the purpose. neighbor to mean), BGP The network command, only the local routing loaded into BGP one way process. Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 ,ccnp rs track, then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing, and the R2 is no longer to R3 updated RIP 's TCP Show mac address-table clear mac address-table // AS200 is the Primary AS and is used to configure the BGP process. After the MAC sublayer of A is added to the MAC address and the LENGTH field, it is sent to the data link. 5.5.5.5 100 If it is RIP , the network specified by the ip default-network command does not need to be displayed to announce RIP , and once the default gateway is specified, RIP BGP comes in 1 and other routes are 20 , and the metric between OSPF remains unchanged. The configuration of SW1 is as follows: The configuration of R2 is as follows: In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: Host address. LocPrf After the command is configured on the interface, the routing table is not updated periodically in this direction, but the update is triggered. The routing table update will be minimal , including only the initial exchange information of the routing table and the updated information when the routing table changes. This command is only valid on the serial link and must be configured at both ends of the link to produce an effect.
