IE-WB2: Lab 1

1) Created a task list but did not stick with it

• Need to stick with the task list
• Use the task list as a play book
• Pay close attention to the Core completion topics
• Be sure to include relevant notes if you need to return to a topic

2) Started to late and did not have my own drawing

• Allow more time to get a drawing in place
• Also allow enough time to read through the lab twice
• Begin to include Ethernet trunk drawing and inter-switch access and routed ports

3) Trunking

• Ok
• Task for making all the non-trunk interfaces never become trunk and vice versa is strange.
  • I assumed all interfaces on the Catalysts applied.
  • The solutions guide did not reflect every port on the device

4) VLAN Assignments and VTP

• Mixed VTP domain environment
• Applied VTP domain to Sw1, it was inherited by Sw2 but not SW3
  • Dont know why
  • Did not explore further due to late start
  • Try on my own equipment
• Be careful of not changing initial configurations of native routed interfaces
• Be careful to note where native routed interfaces terminate
• Plan VLAN builds accordingly if the Native routed interface falls on an inter-switch link
• Build VLANs based on the switches need for the VLAN or to support forwarding path requirements

5) Did not configure STP

• Items marked as non-core and did not make it back to the tasks
• Need more technology specific time with STP and STP advance features

6) PVLANs

• Item marked as non-core and did not make it back to the task
• Do a technology overview of PVLANs and VLAN ACLs to gain understanding of task requirements

7) No Frame Relay issues

OSPF

• Discontiguous OSPF area 0 issue
  • Did not see the possibility of a discontiguous Area 0
  • Based on the loss of the FR circuit between R5 and R4
  • Need to be able to identify and be able to fashion a Virtual Link
• Manipulation of OSPF Network types – no problem
• Manipulation of sub-second OSPF timers – no problem
• Manipulation of OSPF backup interfaces
  • Item marked as non-core and did not make it back to the task
  • If I had made it back I would have changed the bandwidth
  • The solution guide used Cost to meet the task requirements
  • Either solution would have worked

9) EIGRP

• Topology configuration – no problem
• External advertisement – no problem
• Authentication – no problem

10) RIPv2

• Configuration – no problem
• Authentication – no problem

11) Redistribution

• Access-list for networks redistributed into EIGRP to be redistributed again into OSPF
  • Created route-map denying the re-entry of the networks back into EIGRP
  • Happy as I saw this before I started configuring redistribution
  • Did a better job of planning the redistribution methodology
• Interesting EIGRP distance experience
  • Task required that R5 prefer the OSPF path over the EIGRP path to a Loopback address inside the EIGRP topology
  • I chose to manipulate the distance in EIGRP
    • access-list 1 permit 150.18.1.0 0.0.0.255
    • distance 121 0.0.0.0 0.0.0.0 1
  • This configuration worked and changed the AD to 121
  • I do not know if this is wrong as the solution guide indicated a distance command in the OSPF process
  • Also, I learned that if this address were redistributed into EIGRP, then the distance command under the EIGRP process would not have worked
  • You have to use the distance eigrp command to change the AD for all external routes
  • Alternatively, the AD can be changed in the other protocol being redistributed into

12) BGP

• Route reflection gave me a problem in AS 200
  • Could not see the Client/Non-Client Relationships well enough
  • Will need to practice this a few times
• Question: What are the BGP Route Reflection Cluster Rules?
• Question:  I observed that the NLRI for the multi-homed AS attached did not replicate through to the RR clients, Why?
• Best Path selection using Local-Preference
  • failed this task
  • Applied the route-map adjusting local-preference correctly
  • Forgot to match the prefix’s based on AS-Path
• Best Path selection using MED
  • Did not plan for or appropriately configure the next-hop-self command on R5 to R3

13) IP Multicast

• Enabling Multicast routing and PIM Interfaces – no problem
• Configure Auto RP – no problem
• Configure IGMP test – no problem
• Configure IGMP filter – no problem
• Work On
  • Do technology lab on Auto-RP
  • Labs on BSR
  • Labs on advanced Mcast configurations

14) No IPv6 problems

15) QoS

• Need to review FRTS math
• Policing – No problem

16) Skipped Security section and did not have enough time to go back to it.  Need to review all security topics

17) System management

• RMON
  • Need to work on SNMP server configuration
  • Syslog – no problems
• NTP
  • Confused NTP master prefer and NTP peer
  • Need to work on all NTP topics

18) IP Services

• Traffic Accounting – No problems
• HSRP – no problems
• NAT – no problems

Overall, nowhere near where I want to be.  This lab is rated as the easiest in the workbook and I clearly failed it.  So, a lot of work to do and not a whole lot of time to do it.
