Switch(config-if)# spanning-tree [ vlan vlan-id ] cost cost 1.0.0.0/8 route The configuration of R1 is as follows: Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). DMZ-Link Bw can only configure single-hop EBGP neighbors on this router. ? PVLAN configuration creates the primary VLAN : In order to let R4 know that R5 is its federated EBGP neighbor, instead of a normal EBGP neighbor, you need to add the following configuration: We found that both O , O IA or with the FA 's OE2 routes are redistributed into BGP later, these BGP routes Next-hop are they in OSPF the IGP next hop. At the same time, the network segment where the OSPF direct connection port is activated locally will also be injected into BGP . After the injection, Next_Hop is the router (BGP update source IP) . Show ip bgp summary Portfast Path Control Overview The MAC sublayer is responsible for the following tasks: Ip address 3.3.3.3 255.255.255.0 DTP The TAG field ( 32bits ) is only present in the external LSA . Public In the process of double-point bidirectional routing re-release, many problems may occur, such as sub-optimal paths, potential routing loops, etc. This chapter will discuss this model and existing problems in depth. 200 i A default route will be published into the RIP and passed to other routers. For example, R1 , R2 , and R3 run RIP and open loopback on R1 . ! It can contain up to 25 routing entries. 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 ) Optimum and Distributed Switching As a result , there is no vlan10 user on SW2 , and sw2 will flood the message so that other switches know. Next Hop You can also use the show ip dhcp bingding to capture the client-identifier of the client on the server. Create route-map route-map Match tag 10 Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 Internet address is 10.1.12.2/24 Neighbor 10.1.13.1 remote-as 100 Experiment 1: host-dependent 1,10 BGP routing table entry for 100.100.100.0/24, version 5 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP 100 i If the TCP is successfully established, the BGP process sends an Open message to the neighbor and enters Opensent. The solution is as follows: 1. On the R3 , declare the directly connected network segment of 10.1.13.0 into OSPF , and R5 is the same; 2. Modify it on R3 . Origin IGP, metric 0, localpref 100, valid, internal Local In fact, the establishment of a BGP neighbor relationship requires only one connection. The configuration shown in the following figure can also establish a BGP connection: It does not modify the original data frames, the processing efficiency than 802.1Q higher Route-map test permit 20 router ospf 1 Router bgp 123 ^100$ Revision statement 10.1.25.2 Path not synced, but sync is on *>i100.0.2.0/24 100 i Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 This strategy, we can also do on R3 , but the implementation direction of the strategy is in . Access port processing frame process By modifying LOCAL_PREF to affect the flow properties When the packet enters the router, the router strips the Layer 2 information and then looks up the destination IP address in the CEF table for forwarding. The result of the forwarding decision will point to a neighboring entry in the adjacency list, in which the second layer of character letters that need to be rewritten can be found. 100 Route-map WT1 permit 10 match ip address prefix-list 1 set weight 200 Modify the default AD value of BGP . The command is as follows: Routing Feedback (feedback) is a re-release in the deployment of routing requires a great attention to the phenomenon. As shown above,ccnp route exam cost, R5 will 2) Activate TC while timer , and then send the TC- set BPDU out from all non-edge designated ports and root ports . In this way, topology change information quickly floods the network. None does not send updates ( passive ) 2.0 and 3.0 . Now we can by R2 deployment of a distribution list on the distribute-List , so that R2 update to R1 filter out routing information in // This command is used to advertise the real AS number of the AS outside the federation . learner Through MED affect route choice 18 The AS_PATH can be controlled by the policy to affect the route selection. For example, if you want R3 to reach the 1.1.1.0 network priority R1 , you can make a policy on R2 , as follows: Situation 3 We will find that when the topology changes, the TCN will be generated . However, in some cases, the transition flooding of the TCN may have an unnecessary impact on the network . The interface connected to the PC terminal device on the access layer switch is set to portfast network can be optimized to a certain extent, prevent the PC interface of the switch due to switch updown and excessive the TCN .
