Route-map test permit 10 The route for no-export cannot be more or less. Packets Y Configuring a sample RIP environment Interface fa1/0 In the port field of the circuit-ID suboption, the port numbers start at 3. That is to say, in this field, the port number is from 3 , the first port number is 3 , and so on. For example, a 24- port switch with an SFP slot , port3 is fast x/0/1 , port4 is fast x/0/2 , and so on, port 27 is the x/0/1 port of the sfq module . Where x is the stack member number. ^10[012349]$ External Method 1: Static default route network Show run | in route Active is local So as long as the 1.1.1.0 network is not DOWN , R1 will always send default routes to R2 . Private-vlan primary ? R2#sh cef interface s0/0 policy-statistics input Serial0/0 is up (if_number 4) First of all, the route-map is a very important tool, and it is used in a wide range. When defining a route-map , we use the route-map keyword to associate a custom parameter, such as test . A route-map list by the test string unified representation, you may be in one route-map define a plurality of sequences, a sequence number to a decimal representation, such as the figure above, 10 , When R2 is configured with no validate-update-source , R2 will not verify the RIP update message source, so R2 will accept R1. Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Neighbor 4.4.4.4 route-map LP out Id Switch(config-if)# spanning-tree [ vlan vlan-id ] port-priority pri Origin codes: i - IGP, e - EGP, ? - incomplete In R2 ,ccnp switch ahmed nabil, the energy from each R1 and R3 learning to 100.0 the EBGP route, if arranged on maximum-paths 2 12(_34)?_56 Interface level commands. By limiting the number of ARP packets received on an interface , you can prevent the switch that enables DAI from being attacked by the DoS . Precautions: R1 and R2 run OSPF , and announce the direct connection network and their respective LOOPBACK interfaces. R1 LO1 is 1.1.1.1 and R2 LO1 is 2.2.2.2. The secondary VLAN is divided into a community VLAN and an isolated VLAN . In the example, the static route associated with the next hop does not have this attribute, so it is not matched. Whenever a route is reflected by the reflector, the cluster -ID of the reflector (the cluster) is added to the route's Cluster-list attribute. Method two: neighbor xxx default-originate BGP path attribute BPDU format and operation After deploying DAI , we can define the trust status of the switch interface: trusted , or untrusted , for trusted ports, it will not be received. All clients in the route reflection cluster should establish IBGP connections with and only with all RRs in the cluster. 100 Router(config-dhcp)#network [network address][subnet mask] This type of data transmission service does not need to establish a connection, but it adds an acknowledgment mechanism to the transmission of data, which greatly increases the reliability. 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. In the past, switching was hardware-based forwarding, and routing was software-based forwarding, so the campus network used more switching networks. Switch(config-if)# ip address 192.168.255.1 255.255.255.0 200 Route-map COST1 permit 10 match ip address prefix-list 100 Ip address 100.0.1.1 255.255.255.0 The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first, then B routes will be injected into the OSPF , the finally R3 learned, then R3 , the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
