NS: Source IP is:: Destination IP is FF02::1:FF00:0001 In OSPFv2, only the primary IP of a port can participate in the OSPF protocol. OSPF is basically pre-configured. When configuring DR/BDR, pay attention to cle ip ospf pro. However, the version requires that "network" cannot appear, so I delete it and enable it on the interface. 3.

I have learned a word since childhood: struggle! But what is the struggle? Give yourself a minute to think about this! Everyone and grateful group of people. 2. forwarding / filtering decisions Forward / Decision the Filter 3. loop avoidance Loop TCP is a connection-oriented protocol. Connection-oriented protocols provide more sophisticated flow control and error control than connectionless protocols. TCP can ensure the quality of data transmission, which is more reliable than UDP, but it is slower than UDP because of the need for additional error detection and flow control. Show ip route (1) dir flash: (view the current IOS image file name, you can also use rouote#show version); position. Thinking that learning is a very easy process. Some 2. The data link layer : data error detection , physically address MAC Serial1 is down, Line protocol is down The SSL/TLS protocol works on top of the transport layer (TCP/IP) but below the application layer. Therefore, it can be easily implemented on application layer protocols such as HTTP, Telnet, POP3, IMAP4, SMTP and FTP. There are at least two different initialization methods for SSL security extensions: explicit security and implicit security. CCIE Security 4.0 written and lab exams; the first exam will take place In 3550 creates a Ge 802.1Q trunk roads Ip ospf x area x (overlay behavior) PCA PCB Hilabii puts the network technology to the next level. Then, I continued to participate in some backbone network and provincial network projects. Later, I was responsible for the provincial network projects. Gradually, other vendors in the network also had more equipment. Juniper, Foundry, and Extreme, also included broadband IP.

B judges that A and itself are not in a network segment, and directly delivers the packet to the gateway. If there is no gateway, the request packet of B cannot reach the A server at all, so B and The result of A communication is that the data packet cannot arrive! So I bid farewell to the past every day playing chess and skating, began to set off the TCP / IP principle, computer network technology, but can not find how to configure the network. Later, until one day I saw Cisco network technology training materials, such as the treasure, because I finally found out how to design a network and how to configure it, rather than a bunch of empty theory,ccie lab rental, I feel that it is real. CCIE is just jumping into my eyes at this time. China has 20 CCIEs, knowing that CCIE is going to test for two days. The first day is a lucky one. The next day, the examiner has a plug-in error for troubleshooting. It is said that many people have tested four times, five times or can't pass. , special tortured people. I thought I had to be a CCIE.


The following requirements were pre-configured
l VTP is turned off in all switches
l All required VLAN, including access-ports configuration in all relevant switches are provisioned.
l All required SVI interface in all relevant switches (including IP address and subnets mask) are provisioned.
Configure the network in all sites as per the following requirements:
l Access-port must immediately transition to the forwarding state upon link up, as long as they do not receive a BPDU. Use the minimal number of commands per switch to enable this feature.
l If an access-port receive a BPDU, it must automatically shutdown. Use the minimal commands per switch to enable this feature.
l Ports that were shutdown must attempt to automatically recover after 10 minutes.
l None of the switches may generate a TC.
configure the headquarters’ network as well as the large and medium office networks as per the following requirements:
l all trunks must use dot1q encapsulation
l negotiation of trunking protocol must be disabled in all switches
l distribution switches (SW300, SW301, SW400, SW401, SW500, SW501) must initiate etherchannel negotiation using LACP
l configure layer 2 etherechannel’s number as shown in the ‘diagram 1: main topology’ and ‘diagram 5: layer 2 connections’ (that is use only Po1 and/or Po2)
l ensure that all ports included in etherchannels are effectively in use and bundled in the expected channel
l access switches must see similar output as shown below:




configure the headquarters‘network as per the following requirements:
l SW300 must be the spanning-tree root bridge and must maintain a single spanning-tree instance for the following VLANs: 2000, 2002, 2004, 2006, 2008 (use instance number 2)
SW301 must be the spanning-tree root bridge and must maintain a single spanning-tree instance for the following VLANs: 2001, 2003, 2005, 2007, 2009 (use instance number 1)
l all other VLANs, except 3001, must share the default spanning-tree instance
l ensure that interface E0/2 of SW 300 and SW 301 is a dot1q trunk and that it switches frames for VLAN 3001 only
l SW300, SW301, and SW 310 must not have any blocked ports for any access VLAN (2000-2009)
l SW310 must have the least chance of being elected the root bridge for any VLAN
l none of the three switches may run more than four instance of spanning-tree at any point in time



configure all access switches in both datacenter networks (SW110, SW111, SW210, SW211) as per the following requirements:

configure the datacenter#1 network as per the following requirements:
l all OSPF devices must exclude the IP prefixes of connected networks when advertising their type 1 router LSA, except for prefixes associated with loopbacks or passive interfaces
l host loopbacks are the only OSPF intra-area prefixes that may appear in any DC devices ‘routing table
