200 300 If you only want to detect the reachability of some next-hop devices, you can configure different route-map serial numbers to selectively use this feature (in the same route-map ). The configuration of SW2 is as follows: Automatic summary About route reflection clusters Command BGP From the message we can see that the size of this IP packet is 1500 bytes. Offset-list 1 out 1 serial 0/0 When the router performs a classless route lookup (by default, ip classless ), it does not pay attention to the class of the destination address. It performs the longest match between the destination address and all known routes bit by bit . Set native vlan on the trunk Internal 0 packets, 0 bytes Network (1) can learn the routing entries of R2 update,ccnp route resources, and the routing table is loaded with Port Protocol vulnerability .* When the interface is up/down , all dynamically learned MAC address entries will be cleared. The statically configured secure address entries remain. Fa0/22 desirable n-isl trunking 1 Adjacency table 100 i Note that at this moment, although SW1 trims the traffic of vlan10 on the fa0/20 port , the fa0/20 port of SW3 does still release the traffic, but in any case, the PCs cannot communicate with each other. Demonstrate, know the role of allowed vlan . Of course, this is the way to manually trim. Verification Experiment 2 Impact of CLUSTER_LIST in BGP Routing Weight 100 200 i The Control field is composed. If the route is passed from an IBGP neighbor and describes the destination outside the AS Re-routing interface connecting the local release, static routing weight is 32768 Routing-based Policy ( PBR ) PBR Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length 10.1.13.1 Let the CISCO router ignore the AS-path attribute during its decision making process After receiving the packet check, R2 finds that this is the IP of the same subnet as the interface that accepts the update package , so accept this update. Therefore, this test, although the interface masks on both sides are different, but can accept each other's updates, and can also ping between 1.1.1.1 and 2.2.2.2 . The default native vlan is vlan 1 AS_PATH type 2 : AS_SEQENCE detailed Ip address 10.1.25.2 255.255.255.0 Instead of choosing R3 ? This is determined according to the routing principle of BGP (see the BGP document of Red Tea Three Cups Zhu SIR ). Here, the final impact of routing is such a rule "preferred routing from EBGP neighbors (relative to IBGP neighbors) "), R2 is the EBGP neighbor of R5 , so it is preferred. Router ospf 100 The traditional STP , which is 802.1D , is that all VLANs share a spanning tree. The advantage of this is that the switch does not use too much resources to calculate multiple spanning trees. However, the defect is that the port is fixed through the block . As a result, traffic on the network only goes to one side, and some links have no traffic at all, which wastes bandwidth. DHCP Matching as long as the contents of a , b , c , d appear Multilink Multilink-group interface Bibliography 110 Neighbor 1.1.1.1 route-reflector-client Sw(config)#interface range fa 0/3-4 3.3.3.3 The BGP election routeriID rule is the same as OSPF . !! GW has no other configuration about routing The Protected port feature cannot be configured across switches: Aggregate-address summary address attribute-map abc Example of multiplication characters: NEXT_HOP on shared Media (operation on shared media) Distribute-list 62 3.3.3.3 Experiment 1 R4 can learn from R1 and R2 of the 100.0 network routing, and the previous experimental results, we know, without any deployment strategy, R4 preferably RouterID small R3 as destined 100.0 segment BGPpeer , then Can we influence the routing preferences by controlling AS_PATH ? Next, we use route-map to make a policy on R1 , which takes effect on R3 and modifies the AS_PATH path attribute of the 100.0.1.0 route . Eventually, R4 goes to the 1.0 network to go to R2 , and goes to the 2.0 network and still goes to R1 .
