Switch(config)# vtp mode {server | client | transparent} Switch(config-if)# ip address 192.168.255.1 255.255.255.0 Router bgp 345 Half-duplex and full-duplex are the concepts of the physical layer, and the different access modes for the duplex mode of the physical layer are the concept of the data link layer, thus forming an important feature of Ethernet: the data link layer and The physical layer is relevant. Rule example 16 bits Community Aggregator AS_PATH several commands Hello time 3 sec, hold time 10 sec Next hello sent in 1.280 secs In another case, the idea is still the same, RR and Client Aggregate-address summary address as-set advertise-map Ip address 100.0.1.1 255.255.255.0 Use ip community-list to match the community value Ip arp inspection vlan {vlan_ID | vlan_range} But what if the A route is an OSPF external route? The route -map used by exist-map has at least the following two match statements: When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Solution 2 : Free arp The result found can be understood as a pointer to find the associated outbound interface: Multi-hop EBGP Service dhcp TCP Port R2 EIGRP also supports tags . Then the received route becomes 10.1.20.0/24 and the mask is correct . Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, one of external routes it is preferably ( MED not compare) Note that this modification will take effect on all routes sent by R5 (the weight of all routes will become 100 ), and Ip prefix-list 1 seq 5 permit 100.0.1.0/24 ip prefix-list 2 seq 5 permit 100.0.2.0/24 route-map test permit 10 Router bgp 300 The process of processing a VLAN frame by a trunk port is as follows: R3 re-releases the incoming A route, so R2 , R3 , and R4 form a routing loop. The optional parameter length is used to indicate the length of the optional parameter field Send BPDU 192.1.168.2 3 0003.47d9.c8f1 2BB648AB interface-id 584a38f0 END Desirable actively attempts to make the link a trunk (default mode), sending DTP frames, and if the adjacency interface is trunk , desirable , or AUTO , then the interface becomes a trunk . Update-source Layer 3 interface: routing interface ( no swithport or called routed port ), SVI interface Neighbor 10.1.23.2 route-map setCommu in After 10.30.0 is passed to R3 , since the RIP updated subnet and the R3 interface subnet belong to the same main class network, R3 receives the update, and uses the interface mask as the mask of the RIP route, so the R3 routing table The route loaded in is: 10.1.20.0/24 You can use route-map in the following BGP commands. [Results] There is only 1.1.1.0 route in the routing table on R2 . Bgp cluster-id 222.222.222.222 Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. When a data frame is sent from a trunk port, the frame is sent directly. We still have to implement R4 access to 100.0.1.0 network to go R1 , access 100.0.2.0 network to go to R2 , this time we adjust MED , / / View command: Show etherchannel 1 summary 10 FastEthernet0/1 Set community no-advertise route-map test permit 20 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) Route-map test per 10 Set as-path tag After completing this configuration, we can show it: ORIGINATOR_ID and CLUSTER_LIST 1 s> 172.16.2.0/24 EIGRP is run between R1 and R2 . At the same time, R1 and R2 announce their respective LOOPBACK interfaces in the EIGRP process. If R1 turns on auto-summary and network 1.0.0.0 mask 255.0.0.0 , it is advertised to R2 summary route 1.0.0.0/8 Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable Configure BPDU is 0x00 and TCN BPDU is 0x80. The default is shutdown , optional protect , restrict Ip route 3.3.3.0 255.255.255.0 serial 0/1 0 BGP filter-list cache entries using 0 bytes of memory BGP using 417 total bytes of memory RIP redistribute default route protocol 30.30.44.45 /24 IP prefix lookup IPv4 mtrie 8-8-8-8 optimized Input fast flags 0x0, Output fast flags 0x0 ifindex 3(3) R2(config-router)#redistribute rip subnets An entry stored in the log buffer can represent multiple packets. For example, the switch receives the same ARP from the same interface and the same VLAN. New link Link1 between A and Root Router rip Sw(config-vlan)#private-vlan association 201,202 Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. Followed by ACL to match traffic. ? Path 1.1.1.0 backdoor to solve the problem, once the route becomes a local route, the AD value becomes 200 , and the router does not go to its EBGP. Network Local network and re-routed routes, LP defaults to 100 , and can be transmitted to other IBGP neighbors within the AS . The LP is unchanged unless the policy is deployed during transmission. 0xFFFF After R2 show run , I found: Since the configuration of the first experiment Rl , therefore R2 Flights 13 segments, it is preferable that Rl , this time in R2 a clear click BGP neighbor Rl , and the Rl BGP connection DOWN , R2 Flights 13 routes and preferably the R3 , After R2 and R1 restore the BGP connection and receive the 13 route update of R1 again , R2 is still preferred to R3. Iso-igrp metric mobile odr ospf rip Access-list 1 deny 192.168.13.0 access-list 1 permit any Use the clear port-security configured command to clear all manually configured security address entries. Use the clear port-security all command to clear all security address entries. In update their ARP table or will receive the ARP before forwarding the message out to check legality, mainly to see the ARP packets in IP and ! In TCP/IP , the encapsulation format of Ethernet IP data packets is defined by RFC 894 , and the IP data packet encapsulation of IEEE 802.3 network is encapsulated by RFC. Receiving behavior Optimum and Distributed Switching Difficult case 60 Vlans allowed on trunk FastEthernet0/0 Switchport mode private-vlan host The configuration of R2 is as follows: 100 Maximum-paths ibgp 2 , then on R4 , in the ip routing table, there will be load balancing of BGP routes, but note that R4 is 10.1.25.2 Router b 300 Whenever a route is reflected by the reflector,ccnp switch exam guide, the cluster -ID of the reflector (the cluster) is added to the route's Cluster-list attribute. ? Bibliography ^100_ With object tracking, PBR can be more flexible, and can make decisions based on ICMP , HTTP , the presence or absence of a route in the routing table, and the up/down of the interface . 8.1 Overview 91 The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , Then, if an OSPF process (this sentence may not be rigorous, everyone understands what I mean), the route can not be summarized, such as the following figure. *> 100.0.1.0/24 100 Failure case analysis C 1.1.1.0 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets R3 , R4 running the OSPF , the R3 on each can learn from the R1 and R2 of looback A policy-list is like a route-map that only contains a match statement. The configuration of R2 is as follows: Ip community-list 11 permit 100:11 Supported for switch ports and routed ports MED : 150 Use route summarization! Looking at the picture above, in the previous scenario, we need to use 3 fine routes, but here we can achieve the same effect by using only one route. This route is the summary route of the three detailed routes in the previous scenario . A direct benefit of this configuration is that the router's routing table entries are greatly reduced. This mode of operation is called route summarization. Route summarization is a very important network design idea. Usually in a large and medium-sized network design, network and routing optimisation must be considered at all times. Route summarization is a time we need to shut down.
