Set next-hop specifies the address of the next hop , specifying the next hop of BGP . R3 and R4 ,ccnp switch vss, R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . When the community attribute carried in the 11.11.11.0/24 route prefix is " 100:11 no-export ", we do the following test: The same community VLAN can communicate with each other, but the community VLAN must be set up by SVI or router interface to communicate. Request specific routing information: When it is necessary to know the information of a specific route or some specific routes, the request message will be sent together with the routing entry of the specific address. The device that receives the request will process the entries one by one according to the request message and form a response message. So as long as the 1.1.1.0 network is not DOWN , R1 will always send default routes to R2 . Seeing the summary route generated on R3 , AS_PATH inherits the detailed AS_PATH and presents it in the form of {100 , 200} , which can prevent the loop from happening, and will not cause hidden dangers due to the loss of the AS_PATH of the detailed route. . Note that the AS_PATH type in {} is AS_SET and is an unordered list of ASs . Neighbor 10.1.23.3 dmzlink-bw Weight Then 1 , 2 compare first, 1 is preferred (because 1 has a smaller MED ); since 1 and 3 are in the same AS , so again Access-list 1 permit 1.1.1.0 e Match the AS_PATH that does not contain any AS number , that is , the route in the AS . Ip address 192.168.10.254 255.255.255.0 Set as-path tag After " 10.1.20.0 " is passed to R2 , since the updated subnet is consistent with the R2 interface main network, R2 receives the update, and uses the interface mask /23 as the mask of the received RIP subnet, then R2 local loading This RIP route is 10.1.20.0/23 . In fact, the prefix length of the route is wrong. We can configure a secondary address on the R2 interface. In this way, RIP will use the mask of the secondary address (if configured) to receive the route. For example, configure R2 with 10.1.123.222/24 .
