Today I am going to take a dim sum and simply talk about how I got on the technical line. I think it’s a little weird to think about it. There are still some small touches. In and out are relative,ccna security lab, such as: Disable "load rom after netboot fails"? y/n [n]: n (select no) kind of environment is needed for learning, in all fairness, all Define password We have been busy experimenting with experiments, but I have not absorbed It seems that Buff is a stuff, you believe it is still good, "the letter is there, if you don't believe it, there is nothing." I have already arrived in Beijing four days before the exam. Because there are things in the Beijing branch that require me to participate, I came over in advance. My first night, the second night of my super uncomfortable, no window plus Beijing's air conditioning, very uncomfortable! ! ! I personally valued the place, and finally changed a good place, with windows, sunshine, and quiet during the day. Every day after work, I will go to the Yintai Center and walk around. "I will come to customs clearance after two days, waiting for me! CCIE", because I followed a weekend and took a day off. So there are three days to prepare for the exam.
SECTION 1 LAYER 2 TECHNOLOGIES
Section 1.1: LAN Access
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.
section 1.2: LAN distribution
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:
section 1.3: LAN resiliency: spanning-tree
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:
l use 32-bit based values for the default port path cost
l all four switches must use the default value for their interface cost
section 1.4: WAN switching technologies
configure the home router R70 as per following requirements:
l the Ethernet WAN link must rely on a layer 2 protocol that supports authentication and layer 3 protocol negotiation
l the service provider expects that R70 completes a three-way handshake by providing the expected response of a challenge requested
l R70 must use the hostname “R70”and password “CCIE” (without quotes)
l R70 must receive an IP address from R8 and must install a default route pointing to 201.99.8.8
l ensure that R70 can successfully ping 8.8.8.8, which is located in the ISP#2 cloud
l you are not allowed to configure any static route in R70 in order to achieve the previous requirements
l use the pre-configured Dialer 1 interface as appropriate
section 2 layer 3 technologies
section 2.1: OSPF in HQ
configure the headquarters network (BGP AS#65003) as per the following requirements:
l both gateway routers of the headquarters network must always advertise a default route into the ospf domain
l all four devices produce the exact same output as shown below. everything must match, except the “dead time” counters and line order
section 2.2: OSPF in DC#1
in order to speed up OSPF convergence in the datacenter#1 network, limit the number of IP prefixes that are carried in OSPF LSAs that OSPF is preconfigured in all required devices in datacenter#1
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
l your solution must still apply if any new interface was added to the OSPF domain
l don not use any prefix-list or another explicit filter anywhere
l do not configure any interface as unnumbered
l do not remove any pre-configuration
section 2.3: B2B connection with partner#1
R100 is located in the partner#1 network and is connected to R42. it supports OSPF only. configure the large office network as per the following requirements:
l R42 must run a separate OSPF process with R100
l as mentioned in item 2.6, the site gateways R40 and R41 area not allowed to redistribute OSPF into BGP and vice versa
l R42 is allowed to redistribute OSPF into BGP and vice versa
At the end of the exam:
l The server 2 (that is located in the Datacenter#2) must be able to ping the IP address 100.100.100.100/24 (that is located in the partner#1 network)
R100, the partner router, must receive the external prefixes as shown below and no other prefixes:
