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

VTP is turned off in all switches

All required VLAN, including access-ports configuration in all relevant switches are provisioned.

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:

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.

If an access-port receive a BPDU, it must automatically shutdown. Use the minimal commands per switch to enable this feature.

 

Ports that were shutdown must attempt to automatically recover after 10 minutes.

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:

all trunks must use dot1q encapsulation

negotiation of trunking protocol must be disabled in all switches

distribution switches (SW300, SW301, SW400, SW401, SW500, SW501) must initiate etherchannel negotiation using LACP

configure layer 2 etherechannels number as shown in the diagram 1: main topology and diagram 5: layer 2 connections’ (that is use only Po1 and/or Po2)

ensure that all ports included in etherchannels are effectively in use and bundled in the expected channel

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:

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)

 

all other VLANs, except 3001, must share the default spanning-tree instance

ensure that interface E0/2 of SW 300 and SW 301 is a dot1q trunk and that it switches frames for VLAN 3001 only

SW300, SW301, and SW 310 must not have any blocked ports for any access VLAN (2000-2009)

SW310 must have the least chance of being elected the root bridge for any VLAN

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:

use 32-bit based values for the default port path cost

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:

the Ethernet WAN link must rely on a layer 2 protocol that supports authentication and layer 3 protocol negotiation

the service provider expects that R70 completes a three-way handshake by providing the expected response of a challenge requested

R70 must use the hostname R70and password CCIE (without quotes)

R70 must receive an IP address from R8 and must install a default route pointing to 201.99.8.8

ensure that R70 can successfully ping 8.8.8.8, which is located in the ISP#2 cloud

you are not allowed to configure any static route in R70 in order to achieve the previous requirements

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:

both gateway routers of the headquarters network must always advertise a default route into the ospf domain

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:

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

host loopbacks are the only OSPF intra-area prefixes that may appear in any DC devices ‘routing table

your solution must still apply if any new interface was added to the OSPF domain

don not use any prefix-list or another explicit filter anywhere

do not configure any interface as unnumbered

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:

 

R42 must run a separate OSPF process with R100

as mentioned in item 2.6, the site gateways R40 and R41 area not allowed to redistribute OSPF into BGP and vice versa

R42 is allowed to redistribute OSPF into BGP and vice versa

At the end of the exam:

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:

Section 3 VPN Technology

Section 3.3: Internet Access

Section 3.4 LAN to LAN IPsec

Section 4.1: Device Security

Section 4.2: Network Security

Section 5 Infrastructure Security


Section 5.1: System Management
