The above configuration is only to solve the problem of data direction, but the problem of NAT : Router bgp 345 Neighbor 1.1.1.1 weight 2000 sets the route sent by the neighbor to 2000 weight (local) Ip dhcp relay information trust-all Advertised to update-groups: 1 Then the test lines will be powered up for detection. It is found that the 2nd and 3rd lines match, but the matching length of the 2nd line is the longest, so the final result: Database , this database is DHCP Snooping listens for DHCP information recorded after the interaction, inside contains the client's IP , the MAC , belongs to VLAN -related information, etc., and this information, just as ARP 's legality verification. Preferably EBGP route Management adjustments Vlan 10 The network segment of the network local direct interface enters BGP , the MED value is 0 ; the network local static route enters BGP , and the MED value is 0. 192.168.1.0/24 , RIP only declared the direct link (without having to declare that in the process the Loopback ), the R1 on ip defaut-network R5 will receive BGP routes for the 10.0 network from R4 and R3 at the same time . R5 will first prefer R3 because the route that R4 passes to R5 keeps NEXT_HOP and is still R1 . Therefore , the next hop of this route from R4 on R5 . Unreachable, R5 is preferred to R4 by modifying the next hop to itself after R4 modification . Let the CISCO router ignore the AS-path attribute during its decision making process Neighbor maximum-prefix 300 90% warning-only or: Route-map overview No shutdown exit Aggregate-address summary address attribute-map abc Address 2 : RIP-2 ; In the above configuration, the maximum number of secure addresses is set to 3 , and then a secure address is manually configured. Then there are two remaining , and the switch can construct a secure address through dynamic learning. ? 10.1.13.1 Neighbor 3.3.3.3 route-map WT1 in neighbor 5.5.5.5 route-map WT2 in Route-map test permit 10 When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. The two networks of network 100.0 on R1 and R2 enter BGP , then the BGP table on R4 : Next Hop ( If MED is empty , it is set to 0) Route summary issues to be aware of An escape character that is used to convert the control character immediately following it to a normal character Database , this database is DHCP Snooping listens for DHCP information recorded after the interaction, inside contains the client's IP , the MAC , belongs to VLAN -related information, etc., and this information, just as ARP 's legality verification. Preference , will trigger Notifacation message , causing session interruption; but can use IN on AS border router R4 and R2 , we look R2 , R2 moment from R4 has learned this RIP routes, if it from the R3 also learn the route and of the route metric is smaller, then, R2 will preferably from R3 this Routes , so that R1 , R2 , and R3 form a routing loop. Ip community-list 11 permit 100:11 route-map test permit 10 9.9.12.0 is directly connected, FastEthernet0/0 Second layer bundling If R1 starts auto-summary and introduces 1.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. Let's look at the above scenario, focusing on the egress router. This egress router is a three-layer link with the Layer 3 switch. Therefore, you need to configure the backhaul route to the intranet, which is the red font part in the above picture. In this scenario, There are only three network segments on the intranet, so three static routes are configured, but what if there are 100 network segments? Do you want to have 100 routes? As a result, the routing table becomes very large and bloated, which is very inconvenient to maintain and manage. More importantly, this undoubtedly wastes resources of the device. Therefore, from the perspective of network optimization, no matter what kind of network model,ccnp 300-115 gns3, we need to keep an eye on the number of routing entries in the router routing table in the network, whether it is sufficient for optimization, and whether there is room for optimization.
