IP routing table ( IP Routing the Table ) Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially,ccnp route todd lammle pdf, and the route-map is taken without the route . Routing Policy Deception process ARP Request We use ip ospf cost 100 on the F0/0 port of R4 to increase the interface cost , so the result is as follows: The type parameter in the above command is used to indicate the hardware type of this hardware address. If type is 1 , the type is ethernet , if type BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD , these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. Think carefully about what will be wrong, in fact access-list 1 deny 172.16.32.0 is a summary route 172.16. 32.0/21 By default, this database is dynamic, which means that when the switch is restarted, all entries in the database are lost. The result of this event may cause network disruption. So we can store this database as a file, this is the DHCP snooping database agent . The configuration command is very simple, global command: Ip default-network 108 * i Used for unidirectional link detection, mainly for fiber links. Devices that need both ends of the link support UDLD BGP is designed to AS transfer routes between, so it is actually a hop AS . Data forwarding mode STP port status Router(config) router rip R4 has two BGP neighbors, where R3 is its federated IBGP neighbor and R5 is its federated EBGP neighbor. Public ip default-network Metric LocPrf Weight Ip address 192.168.10.254 255.255.255.0 1 : Request message, requesting all or part of the routing information from the neighbor; Route accurate summary algorithm Used to advertise available routes, revoked routes, or both, Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . We look R5 are BGP table: Let's look at the picture and deploy a two-way re-release on R2 and R3 . 100 0 , regarded as infinity Invalidation timer VTP pruning R3 configuration is as follows In the outbound direction, the distribution list can only work on the ASBR that performs the route redistribution action , and can only work on externally imported routes. Because OSPF performs re-release, these external routes are actually imported in the form of routes. Therefore, the distribution list can work normally in this case, but if it is not a local originating external route or an internal OSPF route, the out direction The distribution list is at a loss.
