SW1 still turns on dhcp snooping and inserts option82 Match ip add pre 1 100 R4 has two BGP neighbors, where R3 is its federated IBGP neighbor and R5 is its federated EBGP neighbor. * i Remarks By default, BGP does not allow static default routes to be injected when static is re-released ; unless it is in the BGP process at the same time default-information originate 100 Peer state name Switching, and store the information in the cache, all subsequent data packets , you can not interrupt the system processor to perform queries and other operations , directly from As-path: all specific routes received as numbers are placed in {} , the calculation AS_Path the length of the AS is only counted as . 1 th AS The meaning of this command here is that only 1.1.1.0 is allowed to go out of the route redistributed from the RIP routing protocol (to OSPF , there is no direction, as long as the interface is running OSPF ) Network 11.11.11.0 mask 255.255.255.0 B is passed to its IBGP neighbor C (doing a reflector), then on C , the route NEXT_HOP is still the A router (update source IP ) TCP/IP volume one Neighbor 3.3.3.3 peer-group IBGP_peers neighbor 4.4.4.4 peer-group IBGP_peers The range of TAG values ​​in the external LSA 4.4.4.4 Protocol overview // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 If there are multiple routes from the same neighboring AS and multiple paths are available through Maximum-paths , all routes with the same cost are added to Loc-RIB. R3 is added as follows: Knowledge review The VTP Server and clients synchronize the database with the highest revision number; Configure the aging time type. If you select absolute , that is, absolute time, you need to use the aging time command to set the specific value of the aging time. After the command is pressed, all the security address entries built by the dynamically learned MAC will start. The aging time countdown. If it is the inactivity keyword,ccnp switch revision, the countdown will only start when the dynamic security address entry is inactive (for example, if the host is offline or hanged).
